Correct the parameter setting
Solution
Check external terminals status
Ensure the right external signals have been connected cor-
rectly to the right multi-function external terminals which
are assigned for external error input ([E1.00]...[E1.04] =
32, 33)
Check the stop command via Modbus communication
(0X0088: stop according to parameter setting; 0X0090:
