Hexadecimal representation of trips
Each trip has a unique, eight-digit hexadecimal number
as shown in the tables below. This number is referred to
as the trip mask. The trip masks are used in the Enable,
Active and Warnings parameters in the Trips module.
ID
Trip Name
Possible Reason for Trip
19
COMMS BREAK
Lost option communications:
· A break in option communications has been detected. Refer to option communications ma-
nual.
20
LINE CONTACTOR
DC Link failed to reach the undervoltage trip level within the contactor feedback time.
· The Line contactor failed to connect.
· Missing 3-phase line supply
21
PHASE FAIL
· Not yet implemented ( reserved for large frame)
22
VDC RIPPLE
The DC link ripple voltage is too high:
· Check for a missing input phase
· Repetitive start / stop or forward reverse action.
23
BASE MODBUS BREAK
Lost Base Modbus communications:
· A break in the Base Modbus communications has been detected. Refer to “Appendix A
Modbus TCP”.
24
24V OVERLOAD
24V rail is low
· Output overload due to excess current being drawn from the 24v terminal.
25
PMAC SPEED ERROR
Only for PMAC motor : When using the Start feature in Sensorless Vector Control, the real speed
hasn’t reached the speed setpoint after 5 seconds to move from open to closed loop control or
to move from closed to open loop
26
OVERSPEED
Overspeed:
· >150% base speed when in Sensorless Vector mode
27
STO ACTIVE
Attempt to run the motor with the Safe Torque Off active
· Check the STO wiring. It may be necessary to power the drive off and on to completely clear
this event.
28
FEEDBACK MISSING
The drive has been configured to run in Closed Loop Vector control mode which requires a
Pulse Encoder IO Option, but the IO Option has not been correctly configured.
29
INTERNAL FAN FAIL
An internal cooling fan has failed. This will reduce the lifetime of the power electronics.
· Return the power stack to a Parker Hannifin repair centre.
30
CURRENT SENSOR
Current feedback phase missing
· Check motor phase connections
31
POWER LOSS STOP
A Power Loss Ride Through sequence has occurred and either 1650 Pwrl Time Limit has been
exceeded or the motor speed has reached a zero speed during the sequence.
