PID differential time
0.01s 9999
0.01 to
10.00s
Time required for only the differential (D)
action to provide the same manipulated
variable as that for the proportional (P)
action. As the differential time increases,
greater response is made to a deviation
change.
9999 No differential control.
575
Output interruption
detection time
0.1s 1s
0 to 3600s
If the output frequency after PID operation
remains lower than the
Pr. 576
setting for
longer than the time set in Pr. 575 , the
inverter stops operation.
9999 Without output interruption function
576
Output interruption
detection level
0.01Hz 0Hz 0 to 400Hz
Set the frequency at which the output
interruption processing is performed.
577
Output interruption
release level
0.1% 1000% 900 to 1100%
Set the level ( Pr.577 minus 1000%) to
release the PID output interruption
function.

Set the operation interlock time of MC2
and MC3.
137
Waiting time at a
start
0.1s 0.5s 0 to 100s
Set the time slightly longer (0.3 to 0.5s or
so) than the time from when the ON signal
enters MC3 until it actually turns on.

Inverter output is stopped (motor coast) at
inverter fault.

Operation is automatically switched to the
commercial power-supply operation at
inverter fault (Not switched when an
external thermal error occurs)

Automatic
switchover
frequency between
inverter and
commercial power-
supply operation
0.01Hz 9999
0 to 60Hz
Set the frequency to switch the inverter
operation to the commercial power-supply
operation.

commercial power-

operation
0.01Hz 9999
0 to 10Hz
Valid during automatic switchover
operation (
Pr.139
≠
9999)
When the frequency command decreases
below (
Pr.139 to Pr.159 ) after operation is
switched from inverter operation to
commercial power-supply operation, the
inverter automatically switches operation
to the inverter operation and operates at
the frequency of frequency command.
When the inverter start command (STF/
STR) is turned off, operation is switched
to the inverter operation also.
9999
Valid during automatic switchover
operation (
Pr.139
≠
9999)
When the inverter start command (STF/
STR) is turned off after operation is
switched from the inverter operation to
commercial power-supply inverter
operation, operation is switched to the
inverter operation and the motor
decelerates to stop.
