PU disconnection
Name
PU disconnection
Description
앫
The inverter trips if communication between the inverter and PU is suspended, e.g. the
operation panel or parameter unit is disconnected, when the disconnected PU
disconnection function is valid in Pr. 75 "Reset selection/disconnected PU detection/PU stop
selection".
앫
The inverter trips if communication errors occurred consecutively for more than permissible
number of retries when Pr. 121 "Number of PU communication retries" ≠ "9999" during the
RS-485 communication.
앫
The inverter trips if communication is broken within the period of time set in Pr. 122 "PU
communication check time interval" during the RS-485 communication via the PU
connector.
Check point
앫
Check that the operation panel or the parameter unit is connected properly.
앫
Check the Pr. 75 setting.
Corrective action
Fit the operation panel or the parameter unit securely.
