Short circuit or earth leakage on the motor
side
Fault • Check motor cable.
• Check the length of the motor cable.
• Use shorter or lower-capacitance motor cable.
5 Yes
2340
CiA: Short circuit (inside the device) Fault • Check motor cable for short circuit. 5 Yes
2350
CiA: i²*t overload (thermal state) Fault • Check drive sizing.
• Check machine/driven mechanics for excessive load.
• Check seng of the motor data.
• Reduce values for slip compensaon (P315.01, P315.02) and oscillaon damping (P318.01, P318.02).
5 Yes
2382
