What is Fanuc SV0417 Alarm?

ILL DGTL SERVO PARAMETER: A digital serve parameter setting is incorrect.
[When bit 4 of diagnosis information No. 203 is 1.]
An illegal parameter was detected by the servo software. Identify
the cause with reference to diagnosis information No. 352.
[When bit 4 of diagnosis information No. 203 is 0.]
The CNC software detected an illegal parameter. Probable
causes are given below (see diagnosis information No. 280).
1) The value specified in parameter No. 2020 as the motor model
falls outside the specified range.
2) The motor rotation direction in parameter No. 2022 is not set to
a correct value (111 or -111).
3) The speed feedback pulse count per motor rotation in
parameter No. 2023 is set to a negative or other incorrect value.
4) The position feedback pulse count per motor rotation in
parameter No. 2024 is set to a negative or other incorrect value.

I know this is an old post but for your application I would try armature voltage feedback first. See if it appears stable, and put a clamp on ammeter on it. Let us know how you made out.

Here's the remaining alarms, I will add a list of the applicable models as soon as I can...

• OVERSPEED (This alarms occurs when the speed feedback signal has exceeded 125% of rated speed.)

Parker 590+ Alarms and Faults

I've made a list of the 590+ alarms codes along with the possible reasons and suggestions for clearing the alarms. This is a tedious way of doing things, but hopefully it helps with your problem.

• 3-PHASE FAILED Possible Reasons: Mains voltage incorrect Corrective Actions: Check the mains voltage of the drive (refer to Product Code). This alarm may not operate properly if the voltage is incorrect, i.e. wrong unit or drive OR Possible Reasons: Supply voltage low or missing Corrective Actions: Check auxiliary/control or main supply power OR Possible Reasons:Blown fuse Corrective Actions: Check external branch circuit protection, Check auxiliary/control fuse FT, Check that armature current calibration does not exceed drive rating  OR Possible Reasons: Loose wiring.

• ACCTS FAILED (Note:   The trip prevents the contactor closing and the current loop activating without armature current feedback - important in the case of external stack drives where the thyristor stack is remote from the control board.) Possible Reasons: AC current transformer plug connection to drive power board missing Corrective Actions: Check armature current transformer plug for correct installation.
  
  


• AUTOTUNE ABORT (The Autotune sequence has been aborted. Coast Stop, Program Stop, Enable or Start/Run commands removed before AUTOTUNE procedure completed
  ) Possible Reasons: Wrong AUTOTUNE sequence followed  Corrective Actions: Repeat AUTOTUNE procedure OR Possible Reasons: AUTOTUNE incomplete. (After 2 minutes the drive will time-out if still in AUTOTUNE mode) Corrective Actions: Repeat AUTOTUNE procedure. If problem persists, contact Eurotherm (Parker SSD) Drives customer service
  
  


• AUTOTUNE ERROR This means there was motor rotation detected during Auto-tune process (speed feedback has exceeded 20% of rated speed), or field current detected during Auto-tune (field current feedback has exceeded 6% of rated field current) (Alarm only operates during the Auto-tune sequence) Possible Reasons: Residual motor flux when field supply is disconnected Corrective Actions: Series fields are not recommended for regenerative drives and the series field winding should normally be left open circuit.  OR  Possible Reasons: Permanent magnet motor Corrective Actions: Lock motor armature and repeat Auto-tuning procedure OR  Possible Reasons: Separately supplied field Corrective Actions: Disable external field supply and repeat Auto-tuning procedure

• CONFIG INHIBIT (This means the configuration procedure incomplete. CONFIGURE ENABLE is left in an enabled state) Possible Reasons: The drive was requested to start whilst in Configuration mode. Corrective Actions: Do not attempt to start the drive in Configuration mode  OR  Possible Reasons: Encoder or Micro-tach feedback option card incorrectly fitted to control door Corrective Actions: Check board fully inserted in control door OR  Possible Reasons: Fiber optic cable too long or cable distorted (bend radius too small for example) resulting in too weak a signal at Micro-tach receiver (under drive)  Corrective Actions: Reduce the tightness of the bend. The fiber optic wire should not be bent tighter than a 2" (5cm) radius  OR Possible Reasons: Fiber optic cable too short resulting in too strong a signal at Micro-tach receiver (over drive) Corrective Actions: Back the fiber optic cable out of the receive slightly and re-tighten
  
  



• ENCODER FAILED (There is no speed feedback signal) Possible Reasons: Optional Encoder board is not fitted Corrective Actions: The SPEED FBK SELECT parameter is set to ENCODER but board not fitted OR Possible Reasons: Wire-ended encoder wires loose  Corrective Actions: Check cable and connections OR Possible Reasons: Microtach encoder wires loose or damaged Corrective Actions: Check fibre optic cable for damage,  bend radius, operating length - refer to Microtach handbook.

• FIELD OVER I (This alarm appears because the motor field current has exceeded 120% of the calibrated value) Possible Reasons: Regulator failure Corrective Actions: Contact Parker Support OR  Possible Reasons: Badly tuned control loop (alarm only operates with field current control mode selected) Corrective Actions: Retune control loop
  
  


• HEATSINK TRIP This simply means the drive heatsink temperature is too high, It must be allowed to cool in order to re-start the drive.

Ripple from the speed loop from either the setpoint or feedback can cause unstable current.) Possible Reasons: Drive not Autotuned (unstable current loop)  Corrective Actions: Perform the AUTOTUNE procedure
  OR Possible Reasons: SCR gate connection loose Corrective Actions: Check SCR gate connections from the trigger board to the SCR gate leads
  OR Possible Reasons: SCR defective Corrective Actions: Check SCRs with an ohmmeter.
  OR Possible Reasons: SCR firing pcb defective Corrective Actions: Replace the pcb
  OR Possible Reasons: Motor has opened or shorted coil Corrective Actions: Check the motor with an ohmmeter and megger for insulation and continuity

  OR Possible Reasons: Speed loop gain too high Corrective Actions: Retune drive speed loop
  
  


• OP STATION Possible Reasons: Keypad has been disconnected from drive whilst drive is running in local control. Corrective Actions: Do not remove under these conditions
  
  
  


• OVER I TRIP (this alarm is caused by an armature overcurrent trip. The armature current has exceeded 280% of calibration value

(Still a few more to come...)

Quote(Also, I wonder if anyone can post the complete alarm list for the 590+ SSD drives. I see they are listed on the site here for other older Parker drives.)

I can compile a list of 590+ Alarms similar to the other lists I put together, just give me some time. As for using an ohmmeter to test the field winding, I agree with testing in both places, at the motor and at the drive, just make sure you take the wires out of the terminal block at the drive first.

Another simple static test is to check for any crossover from the field winding to the armature winding. And of course, check for any continuity to ground. these tests can also be performed using a megger for more accurate results.

I'm not sure of all the Parker models these faults pertain to. I am pretty sure that they are for these SSD models at least:

• 650/00F3/230/SNN
• 650/00F5/230/SNN
• 650/00F7/230/SNN
• 650/0001/230/SNN
• 650/0002/230/SNN
• 650/0003/230/SBN
• 650/0005/230/SBN

• 650/0010/460/SBN

Here's the Westinghouse HL71B troubleshooting guide, most of which can be found in the Linatrol service manual. I just listed out the possible scenarios along with the general reason for a fault. If you have more specific questions about solving problems with the HL71B, just ask and I'll see what I can suggest.

Good Luck and happy troubleshooting!

I can list out some of the HL71B troubleshooting guide that I have in our Linatrol service manual. Maybe this will send you in the right direction without having a HL71B service manual of your own.

The HL71B can have many applications, ours in in an automated torching machine. Lets' start with the alignment guide which is always helpful. It may point you in the right direction or it might be useful in the future if you continue to use the HL71B as your control. This part may or may not pertain to your machine.

There's more to come as soon as I can put it together and get it posted.

My rule is one failure is possible with any brand of motor, drive, or encoder system, it happens... But when you repeatedly have problems with damaged components in your drive system, then you should take a second look at the installation and other factors that surround the system.

I compiled a list of the faults that are listed in the SSD drive manual along with a few simple suggestions for clearing them. This is the for the 650 series but it may actually be valid for other models, you'll have to determine that on your own.

• dCH1 OVERVOLTAGE: The drive internal dc link voltage is too high; possible reasons for fault: the supply voltage is too high, You're trying to decelerate a large inertia load too quickly, DECEL TIME time too short, or The brake resistor is open circuit


• dCLO UNDERVOLTAGE: DC link low trip; which means the supply vltage is too low, test and troubleshoot with a voltmeter.


• i HI OVERCURRENT: The motor current being drawn from the drive is too high; There are many possible reasons for this fault:You're trying to accelerate a large inertia load too quickly, ACCEL TIME time too short, you're trying to decelerate a large inertia load too quickly, DECEL TIME time too short, Application of shock load to motor, Short circuit between motor phases, Short circuit between motor phase and earth (ground), Motor output cables too long or too many parallel, motors connected to the drive, or FIXED BOOST level set too high.


• HOt HEATSINK: The ambient air temperature is too high, poor ventilation or spacing between drives. This fault is caused by improper installation or inadequate cooling.


• Et EXTERNAL TRIP: The external trip input is high, Check configuration to identify the source of the signal (non-standard configuration).


• It INVERSE TIME: A prolonged overload condition, exceeding the Inverse Time allowance, has caused the trip which means you must find and remove the overload condition.


• LOOP CUURENT LOOP: A current of less than 1mA is present when 4-20mA setpoint is selected, in this case, look for a broken wire or a loose connection.


• StLL MOTOR STALLED: The motor has stalled (not rotating) Drive in current limit >200 seconds; possible causes for this fault: The motor loading is too great or FIXED BOOST level set too high.


• t 3 ANIN FAULT: AIN2 overload on terminal 3: Overcurrent applied in Current mode to terminal 3, remove or correct source of overcurrent.


• dISP DISP/KEYPAD: Keypad has been disconnected from drive while drive is running in Local Control; simply means the keypad was accidentally disconnected from drive  (indicated over Comms, or by a second keypad).


• SCI LOST COMMS: Lost communications; possible causes for communication fault: COMMS TIMEOUT parameter set too short, Master device failed, The wiring is broken, or there is an incorrect comms setup.


• CntC CONTACTOR FEEDBACK: Contactor feedback signal lost: Check connection to the terminal wired to "contactor closed" parameter in Sequencing Logic (non-standard configuration).


• Ot MOTOR OVERTEMP: The motor temperature is too high; possible causes for this fault: Excessive load, the motor voltage rating incorrect, FIXED BOOST level set too high, Prolonged operation of the motor at low speed without forced cooling, Break in motor thermistor connection.
• I HI CURRENT LIMIT: Software overcurrent trip; If the current exceeds 180% of stack rated current for a period of 1 second, the drive will trip. This fault is caused by shock loads. Remove the shock load and test. Possible causes for this fault include ACCEL TIME and/or FIXED BOOSTset too high, or DECEL TIME set too low, so it can be cleared by making adjustments to the drive calibration.


• LSPd LOW SPEED OVER I: The motor is drawing too much current (> 100%) at zero output frequency; This fault is caused by FIXED BOOST level set too high.



• t 4 10V FAULT: +10V REF overload warning (terminal 4), it is a 10mA maximum, use a multimeter to determine the source of the overcurrent.



• Shrt DESATURATION: Desaturatlon has occurred; this is iInstantaneous overcurrent. Refer to OVERCURRENT fault for more info on clearing this fault.



• dCRP DC LINK RIPPLE: The DC link ripple voltage is too high; possible cause for this fault would be a missing phase, check incoming power supply for all three phases.



• dbSC BRAKE SHORT CCT: Brake resistor overcurrent; Check the brake resisitor value is greater than the minimum allowed.



• t 5 ANOUT FAULT: AOUT overload at terminal 5; check for current at terminal 5, it is rated for 10mA max.



• t 9 DIGIO 1 (T9) FAULT: DIN3 overload on Terminal 9; check for too much current, it is rated 20mA max, use a multimeter to determine the cause of the overcurrent.



• t 10 DIGIO 2 (T10) FAULT: DOUT2 overload at terminal 10; check for overload since max current for this output is rated at 50mA.



• trIP UNKNOWN: Unknown trip with unknown cause (I got this from the manual)

• ICAL ICAL: Zero I current calibration; current sensor calibration fault, cycle the power to the drive, if persistent contact factory or replace the drive.



• COdE PRODUCT CODE ERROR: Switch the drive off and back on (cycle power), if it is persistent, replace drive/ contact factory or your Parker SSD rep.



• CAL CALIBRATION DATA ERROR: Switch the drive off and back on (cycle power), if it is persistent, replace drive/ contact factory or your Parker SSD rep.



• dATA CONFIGURATION DATA FAILURE: Press the "E" button to accept the default configuration, if this fault persists, contact the factory or replace the drive.

Rexroth Indradrive Fatal Errors (Fault Codes)

Here is a simple list of fatal errors that I have from one of the older Rexroth Indramat drives. These are the fatal errors, the way I always understood it, F means "failure" or "fatal" when it comes to the Rexroth Fault Codes. I broke the list into sections per thousands (ie F2000's, F3000's, F4000's, etc) and I broke this list into two posts since it might be too big to put into one.

The F2000's:

• F2003 Motion step skipped
• F2004 Error in motion profile
• F2005 Cam shaft invalid
• F2006 MMC was removed

• F2008 RL The motor type has changed
• F2009 PL Load parameter default values
• F2010 Error when initializing digital I/O

In general, Bus Inhibit Alarm means the the DC bus has been disabled due to an overvoltage. DC bus overvoltages sometime come from too much inertia which overwhelms the regen circuit. It can also be inhibited thanks to an internal drive fault such as component failure.

You can take this alarm literally. Motor Slow Response simply means that the motor is not responding to the command signal fast enough. This can generally be solved with motor tuning...

Get out your scope... If you look at you waveform as the motor makes its move, you'll see it approach its destination very cautiously. The motor will have to be tuned to be more aggressive. Consult your manuals for tuning procedure and get to it!
