0
No Fault
No Fault present
-
2
Auxiliary Input.
External trip (Auxiliary) input.
•
Check remote wiring.
•
Verify communications programming for intentional fault.
3
Power Loss.
Single phase operation detected with excessive load.
•
Monitor the incoming AC line for low voltage or line power interruption.
•
Check input fuses.
•
Reduce load.
4
UnderVoltage.
DC bus voltage fell below the minimum value.
•
Monitor the incoming AC line for low voltage or line power interruption.
5
OverVoltage.
DC bus voltage exceeded maximum value.
•
Monitor the AC line for high line voltage or transient conditions. Bus overvoltage can also be
caused by motor regeneration. Extend the decel time or install dynamic brake option.
6
Motor Stalled.
Drive is unable to accelerate or decelerate motor.
•
Increase P041, A442, A444, A446 [Accel Time x] or reduce load so drive output current does not
exceed the current set by parameter A484, A485 [Current Limit x] for too long.
•
Check for overhauling load.
7
Motor Overload.
Internal electronic overload trip.
•
An excessive motor load exists.Reduce load so drive output current does not exceed the current
set by parameter P033 [Motor OL Current].
•
Verify A530 [Boost Select] setting.
8
Heatsink OvrTmp. Heatsink/Power Module temperature exceeds a predefined value.
•
Check for blocked or dirty heat sink fins. Verify that ambient temperature has not exceeded the
rated ambient temperature.
•
Check fan.
9
CC OvrTmp.
Control module temperature exceeds a predefined value.
•
Check product ambient temperature.
•
Check for airflow obstruction.
•
Check for dirt or debris.
•
Check fan.
12
HW OverCurrent.
The drive output current has exceeded the hardware current limit.
•
Check programming. Check for excess load, improper A530 [Boost Select] setting, DC brake
volts set too high or other causes of excess current.
13
Ground Fault.
A current path to earth ground has been detected at one or more of the drive
output terminals.
•
Check the motor and external wiring to the drive output terminals for a grounded condition.
21
Output Ph Loss.
Output Phase Loss (if enabled).
Configure with A557 [Out Phas Loss En].
•
Verify motor wiring.
•
Verify motor.
29
Analog In Loss.
An analog input is configured to fault on signal loss. A signal loss has
occurred.
Configure with t094 [Anlg In V Loss] or t097 [Anlg In mA Loss].
•
Check for broken/loose connections at inputs.
•
Check parameters.
33
Auto Rstrt Tries.
Drive unsuccessfully attempted to reset a fault and resume running for the
programmed number of A541 [Auto Rstrt Tries].
•
Correct the cause of the fault and manually clear.
38
Phase U to Gnd.
A phase to ground fault has been detected between the drive and motor in
this phase.
•
Check the wiring between the drive and motor.
•
Check motor for grounded phase.
•
Replace drive if fault cannot be cleared.
39
Phase V to Gnd.
40
Phase W to Gnd.
Alarm: External alarm
Fault
code: Cause
Solution
2001
External alarm signal is activated or Normally Open / Normally
Closed settings in HydroSens is setup wrong.
•
Check settings in HydroSens menu and compare with customer
request.
•
Check with customer to find external alarm source.
•
Alarm can only be reset after external equipment allow system to be
reset. Reset has to be done manually.
