Parker AC10 Drive

Fault CodeCause & Solution
AErr Line Disconnected

– Analog signal line disconnected
– Signal source is broken
– Change the signal line
– Change the signal source
CE
Communication
Timeout
Communication fault
– PC/PLC does not send command at fixed time
– Check communication line for reliable connected
Err1
Password
is Wrong
Cause: Password is Wrong.

Solution:

– When password function is enabled, password is set wrong
– Set password correctly
Err2
Tuning
Parameters
Wrong
Cause: Tuning Parameters Wrong

Solution:

– incorrect motor parameters entered
– Connect motor correctly
– Enter correct motor data
Err3
Current
Malfunction
Before
Running
Cause: Current MalfunctionBefore Running.

Solution:

– Current alarm signal exists before running
– Check if control board is properly connected to power board
Err4
Current Zero
Excursion
Malfunction
Cause: Current Zero Excursion Malfunction.

Solution:

– Flat cable is loosened
– Current detector is broken
– Check the flat cable
Err5
PID
Parameters
are set
Wrong
Cause: PID Parameters are set Wrong.

Solution:

– PID parameters are set wrong.
– Set the parameters correctly.
FL
Flycatching
Fault
Cause: FL Flycatching Fault.

Solution:

– Flycatching failure.
– Track again.
GP
Ground
fault
Cause: GP Ground fault.

Solution:

– Motor cable is broken and short- circuit to earth
– The insulation of motor is broken and short circuit to earth
– Inverter has fault
– Change motor cable
– Repair or replace motor
– SEE ALSO: OC, OC2 and ERR4
L.U. / LU
Under-Voltage
Cause: Under-Voltage Protection.

Solution:

– Low voltage on the input side
– Check if supply voltage is normal
– Check if parameter setting is correct
OC/OC2
Overcurrent
Cause: Overcurrent.

– Too short acceleration time
– Short circuit at output side
– Locked rotor with motor
– Parameter tuning is not correct
– Prolong acceleration time
– Ask if motor is cable broken
– Check if motor overloads
– Reduce VVVF compensation value
– Measure parameter correctly
OC1
Overcurrent
Cause: Overcurrent.

– Too short acceleration time
– Short circuit at output side
– Locked rotor with motor
– Parameter tuning is not correct
– Prolong acceleration time
– Ask if motor is cable broken
– Check if motor overloads
– Reduce VVVF compensation value
– Measure parameter correctly
O.E. / OE
DC
Over-Voltage
Cause: DC Over-Voltage.
– Supply voltage too high
– Load inertia too big
– Deceleration time too short
– Motor inertia rise again
– Parameter of speed loop PID is set abnormally

Solution:

– Check if rated voltage is input
– Add braking resistance(optional)
– Increase deceleration time
– Set the parameter of rotary speed loop PID correctly
O.H. / OH
Heatsink
Overheat
Cause:

– Environment temperature too high
– Poor ventilation
– Fan damaged
– Carrier wave frequency or compensation curve is too high

Solution:

– Improve ventilation
– Clean air inlet and outlet and radiator
– Install as required
– Change fan
– Decrease carrier wave frequency or compensation curve
O.L1 / OL1
Inverter
Overload
Cause & Solution:

1. Inverter Overload

– Load too heavy
– Reduce load; check drive ratio
– Increase inverter’s capacity
O.L2 / OL2
Motor
Overload
Cause & Solution:

1. Motor Overload.

– Load too heavy
– Reduce load: check drive ratio
– Increase motor’s capacity
PCE
PMSM
tuning
fault
Cause & Solution:

PMSM tuning fault

– Load is too heavy
– Motor parameters measurement is wrong
– Decrease the load
– Measure motor parameters correctly
P.F1. / PF1
Input Phase
Loss
Cause & Solution:

Input Phase Loss.
– Phase loss with input power
– Check if power input is normal
– Check if parameter setting is correct
PF0
Output
Phase Loss
Cause & Solution:

Output Phase Loss.
– Motor is broken
– Motor wire is loose
– Inverter is broken
– Check if wire of motor is loose
– Check if motor is broken
