Parker AC890 Drive

Fault CodeCause & Solution
DCHI
OVERVOLTAGE
Cause: The drive internal dc link voltage is too high

Solution:

– The supply voltage is too high
– Trying to decelerate a large inertia load too quickly
– The brake resistor is open circuit
DCLO
UNDERVOLTAGE
Cause: The drive internal dc link voltage is too low.

Solution:

– The supply voltage is too low
– The supply has been lost
– A supply phase is missing
OC
OVERCURRENT
Cause: The motor current being drawn from the drive is too high

Solution:

– 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
STO
SAFE
TORQUE OFF
Cause: Safe Torque Off (STO) is active.

Solution:

– One or both STO user inputs is low
– A fault has been detected in the STO circuit
HOT
HEATSINK
Cause: The drive heatsink temperature is too high

Solution:

– The ambient air temperature is too high
– Poor ventilation or spacing between drives
ET
EXTERNAL
TRIP
Cause: User trip caused via control terminals.

Solution:

– +24V not present on external trip (terminal X15/05)
– Check setting of EXT TRIP MODE parameter
IN 1
INPUT 1
BREAK
Cause: I/O TRIPS:: INPUT 1 BREAK has gone True.

Solution:

– Check configuration to determine source of signal
IN 2
INPUT 2
BREAK
Cause: I/O TRIPS:: INPUT 2 BREAK has gone True.

Solution:

– Check configuration to determine source of signal
STLL
MOTOR
STALLED
Cause: The motor has stalled (not rotating).

Solution:

– Motor loading too great
– Current limit level is set too low
– Stall trip duration is set too low
– Fixed or auto boost levels are set too high
IT
INVERSE
TIME
The inverse time current limit is active: motor loading is too great; fixed or auto boost levels are too high (Full Load Current = 150% for 60 seconds).
DB R
BRAKE
RESISTOR
Cause: External dynamic braking resistor has been overloaded.

Solution:

– Trying to decelerate a large inertia load too quickly or too often
DB S
BRAKE
SWITCH
Cause: Internal dynamic braking switch has been overloaded.

Solution:

– Trying to decelerate a large inertia load too quickly or too often.
DISP OP
STATION
Cause: Keypad has been disconnected from drive whilst drive is running in local control

Solution:

– Keypad accidentally disconnected from drive
SCI
COMMS BREAK
COMMS BREAK parameter set to True (refer to I/O TRIPS menu at level 3)
CNTC
CONTACTOR
FBK
The CONTACTOR CLOSED input in the SEQUENCING LOGIC function block remained FALSE after a run command was issued.
SPD
SPEED
FEEDBACK
SPEED ERROR > 50.00% for 10 seconds.
AOT
AMBIENT
TEMP
The ambient temperature in the drive is too high.
OT MOTOR
OVERTEMP
Cause: The motor temperature is too high.

Solution:

– Excessive load
– Motor voltage rating incorrect
– FIXED BOOST and/or AUTO BOOST set too high
– Prolonged operation of the motor at low speed without forced cooling
– Check setting of INVERT THERMIST parameter in I/O TRIPS menu at level 3.
– Break in motor thermistor connection
I HI
CURRENT
LIMIT
Cause: V/Hz mode only- If the current exceeds 180% of induction stack rated current for a period of 1 second, the drive will trip. This is caused by shock loads.

Solution:

– Remove the cause of the shock load.
A24SC
24V FAILURE
Cause: The 24V customer output has fallen below 17V

Solution:

– 24V customer output is short circuited
– Excessive loading
LSPD
LOW SPEED
OVER I
Cause: The motor is drawing too much current (>100%) at zero output frequency.

Solution:

– FIXED BOOST and/or AUTO BOOST set too high (refer to FLUXING menu at level 3).
PHAS
PHASE FAIL
One or more input phases not present.
ENC 1
FBK ENCODER
FAIL
Encoder fault
SHRT
DESAT
(OVER I)
Instantaneous overcurrent. Refer to OVERCURRENT in this table.
DCRP
VDC RIPPLE
Cause: The dc link ripple voltage is too high.

Solution:

– Check for a missing input phase.
DBSC
BRAKE
SHORT CCT
Cause: Brake resistor overcurrent

Solution:

– Check brake resistance is not less than minimum value allowed
– check wiring and brake resistor for earth faults
OSPD
OVERSPEED
Speed feedback > 150% for 0.1 seconds.
ANIN
ANALOG
INPUT
ERR
4-20mA analog input current > 22mA could damage the input circuit.
DBCT
INT DB
RESISTOR
1. Braking mode set to INTERNAL (future use only).
– Set to EXTERNAL and connect an External Braking Resistor if braking is required.
TRIP
UNKNOWN
An unknown trip – refer to Parker Hannifin Manufacturing
TR32
OTHER
Refer to OTHER in Appendix D: TRIPS STATUS. One or more trips have occurred with a Value greater than 32. See the list.
ATN1
MAX SPEED
LOW
During Autotune the motor is required to run at the nameplate speed o f 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.
ATN2
MAINS VOLTS
LOW
The mains input voltage is not sufficient to carry out the Autotune.
– Re-try when the mains have recovered.
ATN 3
NOT AT
SPEED
The motor was unable to reach the required speed to carry out the Autotune.
– Possible reasons include: motor shaft not free to turn; the motor data is incorrect
ATN4
MAG CURRENT
FAIL
It was not possible to find a suitable value of magnetising 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.
ATN5
NEGATIVE
SLIP F
Autotune has calculated a negative slip frequency, which is not valid.

– Nameplate rpm may have been set to a value higher than the base speed of the motor.
– Check nameplate rpm, base frequency, and pole pairs are correct.
ATN6
TR TOO
LARGE
Cause: The calculated value of rotor time constant is too large.

Solution: Check the value of nameplate rpm.
ATN7
TR TOO
SMALL
Cause: The calculated value of rotor time constant is too small.

Solution: Check the value of nameplate rpm.
ATN8
MAX RPM
DATA ERR
Cause & Solution:

This error is reported when the MAX SPEED RPM is set to a value outside the range for which Autotune has gathered data. Autotune gathers data on the motor characteristics up to 30% beyond “max speed rpm”.

– If MAX SPEED RPM is later increased beyond this range, the drive had no data for this new operating area, and so will report an error.
– To run the motor beyond this point it is necessary to re-autotune with MAX SPEED RPM set to a higher value.
STAC
STACK TRIP
The drive was unable to distinguish between an overcurrent/desat or overvoltage trip.
ATNA
LEAKGE L
TIMEOUT
Cause: The leakage inductance measurement requires a test current to be inserted into the motor. It has not been possible to achieve the required level of current.

Solution:

– Check that the motor is wired correctly.
PLOS
POWER LOSS
STOP
Power Loss Stop sequence has ramped Speed Setpoint to zero or timed out.
ATNC MOTR
TURNING
ERR

ATNE
AT TORQ
LIM ERR
The motor is in torque limit during Autotune.
ECAL
