This function stops the inverter output if
communication between the inverter and
PU is suspended, for example the
operation panel and parameter unit is
disconnected, when 2, 3, 16 or 17 was
set in [Pr. 75 Reset selection/disconnected
PU detection/PU stop selection].
This function stops the inverter output
when communication errors occurred

connector.
This function also stops the inverter
output if communication is broken for the
period of time set in [Pr. 122 PU
communication check time interval].
If operation cannot be resumed properly
Retry count excess within the number of retries set, this function
trips the inverter.
Stops the inverter output if the

occurs.
When the operation panel power supply (PU

inverter. At this time, the operation panel

the RS-485 terminals cannot be made.
To reset, enter the RES signal or switch power
OFF, then ON again.
When the 24VDC power output from the
terminal PC is shorted, this function shuts
off the power output. At this time, all external
24VDC power
contact inputs switch OFF. The inverter
output short circuit
cannot be reset by entering the RES signal.
To reset it, use the operation panel or switch
power OFF, then ON again.
Because [Pr.167 Output current detection
