These parameters are communication parameters that are not cleared when parameter
clear (all clear) is executed from RS485 communication. (Refer to section 6.18.3 for RS485
communication).

Description
You can select Coasts to stop
the inverter
Decelerates to
operation if a
stop
communica-
tion error Continues run-
occurs. ning at Pr. 779
Motor runs at the specified fre-
quency at a communication error.
Motor runs at the frequency used
before the communication error.
Display the cumulative energizing
time of the inverter in 100h incre-
ments. Reading only
Writing the setting of "0" clears the
cumulative energizing time.
Set the time taken until when the
maintenance timer alarm output
signal (Y95) is output.
No function
Set the frequency to start coasting
to a stop (output shutoff).
No function
Modbus-RTU communication can
be made, but the inverter will
come to trip in the NET operation
mode.
Set the interval of communication
check time. (Same specifications
as Pr. 122)
No communication check (signal
loss detection)
Set the time taken to average the
current during start bit output
(1s).
Set the time for not obtaining
(mask) transient state data.
Set the reference (100%) for out-
putting the signal of the current
average value
* Setting increments and setting
range differ according to the
inverter capacity:
(01160 or less/01800 or more)
