PU disconnection
y
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
].
y
This function stops the inverter output
when 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 with the PU
connector.
y
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
].

Short circuit of
power supply for
operation panel,
power supply for
RS-485 terminals
When the operation panel power supply (PU
connector) is shorted, this function trips the
inverter. At this time, the operation panel
(parameter unit) cannot be used and RS-485
communication from the PU connector cannot
be made.
When the internal power supply for RS-485
terminals are shorted, this function shuts off the
power output. At this time, communication from
the RS-485 terminals cannot be made.
To reset, enter the RES signal or switch power
OFF, then ON again.

24VDC power
output short circuit
When the 24VDC power output from the
terminal PC is shorted, this function shuts
off the power output. At this time, all external
contact inputs switch OFF. The inverter
cannot be reset by entering the RES signal.
To reset it, use the operation panel or switch
power OFF, then ON again.

] is set to the alarm stop
setting (=1), this function is activated when
the output current exceeds the [
