Re-start of the drive is not possible. Speed zero has not been reached. See 21.08 M1 zero speed level.
Set On = Run = 0 and check if the actual speed is within the zero speed limit.
This warning is valid:
− For a normal stop. Off1 command in case of 21.01 Start mode
= Start from zero.
− For a coast stop. Off2 (emergency off/fast current off) command.
− For an emergency stop. Off3 (emergency stop) command.
− Even if the drive power is cycled.
Check:
− The settings of 21.08 M1 zero speed level, 21.01 Start mode and 90.41 M1 feedback selection.
− The function of the used speed feedback devices (tacho / encoder).
