Cause:
- no more signals are detected from the rotary encoder (motor) while driving
Remedial action:
a) Motor shaft rotates continuously:
- check the encoder connection
- observe the value "Cnt" in the INFO menu "Encoder" when turning the motor shaft (e.g. by releasing the brake). If the shaft rotates, the value must rise / fall continuously
b) Motor shaft stops while driving:
- check whether the brake is applied while the cabin is in motion
- for ASM: check the motor data
- check the motor connection (U-U, V-V, W-W)
- increase the parameter "SPD_KP" in "Controller" menu
