Error code Description Classication Remedy Blocking time [s]
2250 CiA: Continuous overcurrent (inside the device) Error
• Check motor and wiring for short circuits.
• Check brake resistor and wiring.
• Check motor circuit (delta connection, star connection).
• Check setting of the motor data.
5
2320 Short circuit or earth leakage on motor side Error
• Check motor cable.
• Check the length of the motor cable.
• Use shorter or lower-capacitance motor cable.
5
2340 CiA: Short circuit (inside the device) Error • Check motor cable for short circuit. 5
2350 CiA: i²*t overload (thermal state) Error
• Check drive sizing.
• Check machine/driven mechanics for excessive load.
• Check setting of the motor data.
• Reduce values for slip compensation (0x2B09:001, 0x2B09:002) and oscillation damping (0x2B0A:001,
0x2B0A:002).
5
