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

sequence
Set the operation interlock time of MC2
0.1s 1s 0 to 100s
and MC3.
Set the time slightly longer (0.3 to 0.5s or
0.1s 0.5s 0 to 100s so) than the time from when the ON signal
enters MC3 until it actually turns on.
Inverter output is stopped (motor coast) at
0
inverter fault.
Operation is automatically switched to the
1 0
commercial power-supply operation at
1
inverter fault (Not switched when an
external thermal error occurs)
Set the frequency to switch the inverter
0 to 60Hz operation to the commercial power-supply
operation.
0.01Hz 9999
9999 Without automatic switchover
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
0 to 10Hz
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
0.01Hz 9999
to the inverter operation also.
Valid during automatic switchover
operation (Pr.139 ≠ 9999)
When the inverter start command (STF/
STR) is turned off after operation is
9999 switched from the inverter operation to
commercial power-supply inverter
operation, operation is switched to the
inverter operation and the motor
decelerates to stop.
