Trips and Fault Finding
650 Series AC Drive
ID
Trip Name
Possible Reason for Trip
18 CURRENT LIMIT
Software overcurrent trip:
•
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 shock load.
•
ACCEL TIME and/or FIXED BOOSTset too high
•
DECEL TIME set too low
21 LOW SPEED OVER I
The motor is drawing too much current (>100%) at zero
output frequency:
•
FIXED BOOST level set too high
22 10V FAULT
10V fault:
•
+10V REF overload warning (terminal 4) -
10mA maximum
24 DESATURATION
Desaturation:
•
Instantaneous overcurrent. Refer to OVERCURRENT in
this table.
25 DC LINK RIPPLE
The dc link ripple voltage is too high:
•
Check for a missing input phase
26 BRAKE SHORT CCT
Brake resistor overcurrent:
•
Check brake resistor value is greater than minimum
allowed
28 ANOUT FAULT
AOUT overload on terminal 5:
•
10mA maximum
29 DIGIO 1 (T9)
FAULT
DIN3 overload on terminal 9:
•
20mA maximum
30 DIGIO 2 (T10)
FAULT
DOUT2 overload on terminal 10:
•
50mA maximum
31 UNKNOWN
Unknown trip
33 ICAL
Zero I Current Calibration:
•
Current sensor calibration fault. Switch unit off/on. If
persistent, return to factory.
