Details regarding the individual error messages
8784 0x2250 CiA: connuous overcurrent (inside the device) Keypad display: PU over current
Cause Error type/response Remedy
•
Connuous overcurrent on the inverter/
motor side.
•
Overcurrent at the brake chopper (brake
transistor).
•
DC bus relay has not been closed due to a
malfuncon.
Fault
•
The inverter is inhibited immediately. The
motor becomes torqueless (coasts).
•
The error can only be reset aer a blocking
me of 5 s.
•
Check motor and wiring for short circuits.
•
Check brake resistor and wiring.
8992 0x2320 CiA: Short circuit/earth leakage (internal) Keypad display: Earth leak
Cause Error type/response Remedy
•
Short circuit/earth fault of motor cable
•
Capacive charging current of the motor
cable too high.
Fault
•
The inverter is inhibited immediately. The
motor becomes torqueless (coasts).
•
The error can only be reset aer a blocking
me of 5 s.
•
Check motor cable.
•
Check length of the motor cable.
•
Use shorter or lower-capacitance motor
cable.
9024 0x2340 CiA: short circuit (inside the device) Keypad display: Motor shorted
Cause Error type/response Remedy
Short circuit of motor cable Fault
•
The inverter is inhibited immediately. The
motor becomes torqueless (coasts).
•
The error can only be reset aer a blocking
me of 5 s.
Check motor cable for short circuit.
9040 0x2350 CiA: i²*t overload (thermal state) Keypad display: i2t motor
Cause Error type/response Remedy
Motor thermally overloaded, e. g. by an imper-
missible connuous current or by frequent or
too long acceleraon processes.
Fault
•
The error can only be reset aer a blocking
me of 5 s.
•
The error type can be congured in 0x2D4B:
003 (P308.03).
•
Check drive dimensioning.
•
Check machine/driven mechanics for exces-
sive load.

too long acceleraon processes.
Fault
•

motor becomes torqueless (coasts).
•
The error can only be reset aer a blocking
me of 3 s.
