Table 71: Warning and Fault Events Summary (continued)
Number Description Warning Fault Trip
lock
Cause
26 Brake Overload X X – The power transmitted to the brake resistor over the last 120 s
exceeds the limit. Possible corrections: Decrease brake energy
via lower speed or longer ramp time.
27 Brake IGBT/Brake
chopper Short Cir-
cuited
– X X Brake transistor is short-circuited, thus brake function is dis-
connected.
28 Brake Check – X X Brake resistor is not connected/working.
30 U phase loss – X X Motor phase U is missing. Check the phase.
31 V phase loss – X X Motor phase V is missing. Check the phase.
32 W phase loss – X X Motor phase W is missing. Check the phase.
36 Mains Failure X X – This warning/fault is only active if the supply voltage to the
drive is less than the value set in P 2.3.7 Power Loss Controller
Limit, and P 2.3.6 Power Loss Action is NOT set to [0] No Func-
tion.
38 Internal Fault – X X Contact the local supplier.
40 Overload T15 X – – Check the load connected to terminal 15 or remove short-cir-
cuit connection.
46 Gate drive Voltage
Fault
– X X –
47 24 V Supply Low X X X 24 V DC may be overloaded.
50 AMA calibration failed – X – A calibration error has occurred.
51 AMA check U
nom
and
I
nom
– X – Wrong setting for motor voltage and/or motor current.
52 AMA low I
nom
– X – Motor current is too low. Check the settings.
53 AMA big motor – X – The power size of the motor is too large for the AMA to oper-
ate.
54 AMA small motor – X – The power size of the motor is too small for the AMA to oper-
ate.
55 AMA parameter range – X – The parameter values of the motor are outside of the accept-
able range. AMA does not run.
56 AMA interrupt – X – The AMA is interrupted.
57 AMA timeout – X – –
58 AMA internal – X – Contact the local supplier.
59 Current Limit X X – The drive is overloaded.
60 External Interlock – X – External interlock has been activated.
61 Feedback Error X X – –
