What is Parker OVERCURRENT alarm mean on a Parker AC drive?

Here's what the troubleshooting guide says: The motor current being drawn from the drive is too high.

• Trying to accelerate a large inertia load too quickly
• Trying to decelerate a large inertia load too quickly
• Application of shock load to motor
• Short circuit between motor phases
• Short circuit between motor phase and earth
• Motor output cables too long or too many parallel
• motors connected to the drive
• Fixed or auto boost levels are set too high

To clear an overcurrent alarm you'll need to look at the list of suggestions from the troubleshooting guide and go through the list to find the reason for your overcurrent situation.

Pressing the "E" button should clear the alarm from the drive but if you don't find the reason behind the overcurrent situation and solve it, it will just return when you least want it.

What is Parker HEATSINK alarm mean on a Parker AC drive?

The manual says: The drive heatsink temperature is too high. The ambient air temperature is too high. Poor ventilation or spacing between drives.

To clear a heatsink alarm you will need to lower the heatsink temperature within the drive. Suggestions from the manual are all reasons for overheating, you just need to find the source of the excessive heat and rectify the situation. Once you lower the temperature or allow the drive to cool off, you can press the "E" button to clear the alarm.

What is Parker EXTERNAL TRIP alarm mean on a Parker AC drive?

the Parker manual says: User trip caused via control terminals, +24V not present on external trip (e.g. terminal 19, Macro 1).

This alarm is most likely caused by the machinery or equipment having a fault or problem which resulted in the external fault contactor opening/closing to notify the drive that there is a problem with the machinery/equipment.

What is Parker INPUT 1 BREAK alarm mean on a Parker AC drive?

from the troubleshooting guide: A signal break has been detected on analog input 1 (terminal 1), Analog input is incorrectly configured for 4-20mA operation, Break in external control wiring

To clear the input 1 break alarm, you will first need to find why it appeared in the first place. If this is a new installation, you can go straight to the input parameters and check that they are configured properly,the most common mistake is selecting 4-20ma instead of 0-10V.

If it is an existing application, it is more likely a wiring problem, you will need to go get your ohmeter/voltmeter and go to work.

What is Parker INPUT 2 BREAK alarm mean on a Parker AC drive?

from the manual: A signal break has been detected on analog input 2 (terminal 2), Analog input is incorrectly configured for 4-20mA operation, Break in external control wiring

To clear the input 2 break alarm, you will first need to find why it appeared in the first place. If this is a new installation, you can go straight to the input parameters and check that they are configured the right way. If it is an existing application, it is more often a wiring problem, you will need to retrieve your ohmeter/voltmeter and go to work.

What is Motor Stalled Alarm on a Parker AC Drive?

The troubleshooting manual says: The motor has stalled (not rotating).

1. Motor loading too great
2. Current limit level is set too low
3. Stall trip duration is set too low
4. Fixed or auto boost levels are set too high

To clear the motor stalled alarm you'll need to research your calibration settings including the setting mentioned in the troubleshooting guide. Also check the physical loading to make sure it moves freely or appropriately.

What is Brake Resistor Alarm on a Parker AC Drive?

The manual says: External dynamic braking resistor has been overloaded Trying to decelerate a large inertia load too quickly or too often

When you set up your dynamic braking installation, resistor sizing  is critical. If the application was in service with no problems, then the resistor sizing isn't the issue unless the load has changed. An overheated braking resistor can also be caused by stopping too frequently.

Quote from: rickpend on October 06, 2016, 10:29:AM
What is Brake Switch Alarm on a Parker AC Drive?

The manual says: Internal dynamic braking switch has been overloaded. Trying to decelerate a large inertia load too quickly or too often

To clear a brake switch alarm, you will need to start with the dynamic braking calibration and verify that it is properly set up, next you need to examine the installation to make sure the load isn't too much for the dynamic braking system. It is possible to overheat the dynamic brake circuit if you are stopping the motor too often also... so there are few places you need to visit when you see this alarm.

What is Contactor Fbk Alarm on a Parker AC Drive?

The troubleshooting guide says: The CONTACTOR CLOSED input in the SEQUENCING LOGIC function block remained  FALSE after a run command was issued

I'm not sure if this alarm is referring to an internal contactor or an external contactor. If the drive is monitoring an internal contactor, you may have a hardware problem.

If it is referring to an external contactor, you can start by verifying the wiring to the external contactor and testing the contactor coil.

What is Speed Feedback Alarm on a Parker AC Drive?

The manual says: SPEED ERROR > 50.00% for 10 seconds

Not much info in the troubleshooting guide, I assume there is either a feedback problem, (encoder or tacho) or it is also possible the motor is being oversped by an external force, for example, a flywheel.

What is Ambient Temp Alarm on a Parker AC Drive?

The manual says: The ambient temperature in the drive is too high

Definition of ambient temperature: the temperature of the surrounding environment

The ambient temperature alarm may have more to do with the drive's installation than the drive itself. Verify that the drive has an appropriate cooling where it is mounted.

What is Motor Overtemp Alarm on a Parker AC Drive?

from the manual: MOTOR OVERTEMP The motor temperature is too high (Excessive load)

1. Motor voltage rating incorrect

2. FIXED BOOST and/or AUTO BOOST set too high

3. Prolonged operation of the motor at low speed without forced cooling

4. Check setting of INVERT THERMIST parameter in I/O TRIPS menu at level 3.

5. Break in motor thermistor connection

There's a few suggestions on the manual, you'll need to identify the source of the excess temperature, resolve the issue, and press "E" to clear the overtemp alarm.

What is Current Limit Alarm on a Parker AC Drive?

The troubleshooting guide says: If the current exceeds 180% of stack rated current for a period of 1 second, the drive will trip. This is caused by shock loads. Remove the cause of the shock load.

Definition of electrical shock load: A substantial, instantaneous, momentary rise in current.

You'll need to put your thinking cap on and investigate the loading of the drive. If this alarm appears on a proven system, then mechanical or physical changes in the system may have occurred. If this alarm appears on a newly commissioned system, then you'll need to  research the drive setup and design.

What is Short Circuit Alarm on a Parker AC Drive?

The troubleshooting simply says this: The output is short circuited

To clear the short circuit alarm, start by disconnecting the output wiring and press "E" If the alarm remains with no wiring attached, then the drive's output circuit has a short circuit and will need some professional repair.

What is 24V Failure Alarm on a Parker AC Drive?

From the Manual: The 24V customer output has fallen below 17V. 24V customer output is short circuited. (Excessive loading)

Most likely mis-wiring of the 24V output or a short circuit to the load or the relay connected at this point. This problem can easily be resolved by temporarily disconnecting the load and troubleshooting from there...

What is Parker UNDERVOLTAGE alarm mean on a Parker AC drive?

The troubleshooting manual says: The drive internal dc link voltage is too low, or the supply voltage is too low, or the supply has been lost, or a supply phase is missing.

To clear the undervoltage alarm you will need a voltmeter to verify all the required voltages and go from there...

Quote from: rickpend on October 06, 2016, 09:50:AM
What is Parker OVERVOLTAGE alarm mean on a Parker AC drive?

The troubleshooting guide says: The drive internal dc link voltage is too high. or the supply voltage is too high, or trying to decelerate a large inertia load too quickly, or the brake resistor is open circuit.

To clear the overvoltage alarm you'll need to use your voltmeter to locate the source of the excessive voltage.

Quote from: rickpend on October 06, 2016, 11:18:AM
What is Low Speed Over I Alarm on a Parker AC Drive?

The troubleshooting guide says: FIXED BOOST and/or AUTO BOOST set too high (refer to FLUXING menu at level 4) The motor is drawing too much current (>100%) at zero output frequency.

To clear this alarm you'll need to check your calibration settings. The manual calls attention to the two "Boost" settings. It is worth trying to autotune the motor again also.

Quote from: rickpend on October 06, 2016, 12:33:PM
What is Encoder 1 Fault Alarm on a Parker AC Drive?

The troubleshooting guide says: The Error input on the Encoder TB is in the Error state.

So I think clearing the encoder 1 fault becomes a matter of verifying the encoder and the encoder wiring, specifically near the connector which is the most common place to find wiring problems.

Quote from: rickpend on October 06, 2016, 12:35:PM
What is Desat Over I Alarm on a Parker AC Drive?

The troubleshooting guide says: Instantaneous overcurrent. The motor current being drawn from the
drive is too high.

To clear the DESAT Over I fault, treat the alarm the same as an OVERCURRENT alarm. Check the motor loading, motor acceleration, short circuit in the motor windings, or possible grounding of one of the motor leads.

Quote from: rickpend on October 06, 2016, 12:37:PM
What is VDC Ripple Alarm on a Parker AC Drive?

The troubleshooting manual says: The dc link ripple voltage is too high. Check for a missing input phase.

Before you can clear this fault, you will need to use your voltmeter to verify the three input phases are present and go from there.

Quote from: rickpend on October 06, 2016, 12:38:PM
What is Brake Short CCT Alarm on a Parker AC Drive?

The manual says: Check resistance brake resistor value is greater than minimum allowed.

This alarm is triggered by brake resistor overcurrent. The cause for the overcurrent can be improper resistor sizing, shorted or melted resistor wiring, or a failed resistor. You'll have to do some research in the brake resistor circuit to clear this fault permanently.

Quote from: rickpend on October 06, 2016, 12:40:PM
What is Overspeed Alarm on a Parker AC Drive?

The manual says: Speed feedback > 150% for 0.1 seconds

It doesn't necessarily tell you why, it just tells you that the drive "believes" it is exceeding the max speed. You should be able to press the "E" button to clear this alarm, however that won't fix the reason for the drive thinking it is overspeeding the motor.

Quote from: rickpend on October 06, 2016, 01:09:PM
What is Max Speed Low Alarm on a Parker AC Drive?

This is what is written in the troubleshooting guide: During Autotune the motor is required to run at the nameplate speed of the motor. If MAX SPEED RPM limits the speed to less than this value, an error will be reported.

Increase the value of MAX SPEED RPM up to the nameplate rpm of the motor (as a minimum). It may be reduced, if required, after the Autotune is complete.

It looks like the max RPM calibration value may be the source of this fault. You'll have to verify that you've got the right value for this setting.

Quote from: rickpend on October 06, 2016, 01:10:PM
What is Mains Volts Low Alarm on a Parker AC Drive?

The manual says: The mains input voltage is not sufficient to carry out the Autotune. Re-try when the mains has recovered.

This "mains alarm" may require a voltmeter to solve the issue. Check for proper incoming voltage and take the appropriate action to clear this alarm.

Quote from: rickpend on October 06, 2016, 01:12:PM
What is Not at Speed Alarm on a Parker AC Drive?

Here is what the manual says: The motor was unable to reach the required speed to carry out the Autotune. Possible reasons include:

1. motor shaft not free to turn
2. the motor data is incorrect

This is self explanatory, it tells you that the autotune wasn't able to finish because the motor shaft was restricted or because the calibration settings were not entered correctly.

Quote from: rickpend on October 06, 2016, 01:13:PM
What is Mag Current Fail Alarm on a Parker AC Drive?

This is from the manual: It was not possible to find a suitable value of magnetizing current to achieve the required operating condition for the motor. Check the motor data is correct, especially nameplate rpm and motor volts.
Also check that the motor is correctly rated for the drive.

It seems like this alarm can only be cleared by verifying and adjusting your calibration. This alarm is triggered by motor settings in particular or possibly an incorrectly sized drive for the motor that you're trying to control.
