PID control

134

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.

Switch between the inverter operation and commercial power-supply operation to use

135

Commercial power-

supply switchover

sequence output

terminal selection

sequence



1

Without commercial power-supply

switchover sequence

136

MC switchover

interlock time

0.1s 1s 0 to 100s

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.



138

Commercial power-

supply operation

switchover

selection at an

alarm

10

0

Inverter output is stopped (motor coast) at

inverter fault.



1

Operation is automatically switched to the

commercial power-supply operation at

inverter fault (Not switched when an

external thermal error occurs)

139

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.



9999 Without automatic switchover

159

Automatic

switchover ON

range between

commercial power-

supply and inverter

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.
