–
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.
X
Brake transistor is short-circuited, thus brake function is dis-
connected.
X
Brake resistor is not connected/working.
X
Motor phase U is missing. Check the phase.
X
Motor phase V is missing. Check the phase.
X
Motor phase W is missing. Check the phase.
–
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.
X
Contact the local supplier.
–
Check the load connected to terminal 15 or remove short-cir-
cuit connection.

X
24 V DC may be overloaded.
–
A calibration error has occurred.
–
Wrong setting for motor voltage and/or motor current.
–
Motor current is too low. Check the settings.
–
The power size of the motor is too large for the AMA to oper-
ate.
–
The power size of the motor is too small for the AMA to oper-
ate.
–
The parameter values of the motor are outside of the accept-
able range. AMA does not run.
–
The AMA is interrupted.
–
–
–
Contact the local supplier.
–
The drive is overloaded.
–
External interlock has been activated.
