Cause:
- a motor overcurrent was detected
Remedial action:
- check the motor connections for short circuit and ground fault
- check the phase sequence of motor connection (U->U; V->V; W->W)
- check the encoder connection and functioning (for further information, see INFO menu "Encoder")
- check the calibration of the absolute value encoder
- check the motor data in the "Motor nameplate" menu
- reduce the parameter "SPD_KP" in the "Control system" menu 
- reduce the parameter "K_START" in the "Start" menu
- for open loop operation (asynchronous operation without encoder): In the menu "Control", set the parameter "UF_ED" to "On", then increase in the menu "Control" the parameter "I_IxR" step by step. Do not exceed the maximum value of 1.5 x rated motor current!
