Multistep PID Command
• Multistep PID Command 1 to 3 (J136, J137, J138)
The PID command value can be applied by the multi-step command of digital input. Allocate “171:
PID-SS1” and “172: PID-SS2” to the input terminals [DI1] to [DI7].
PID-SS2 PID-SS1 PID multi-step command
OFF OFF Not selected
OFF ON
J136: PID Control Multistep PID Command 1 Change range: -999.0 to
0.00 to 9990
ON OFF
J137: PID Control Multistep PID Command 2 Change range: -999.0 to
0.00 to 9990

J138: PID Control Multistep PID Command 3 Change range: -999.0 to
0.00 to 9990
Anti-reset Windup
• PID Control Anti-reset Windup Width (J10)
Restrains overshooting during control by a PID controller
. If the dif
ference between the command
and the feedback value is outside the range of the set value, the integrator holds the value and the
integration operation is not performed.
Data setting range: 0 to 200 (%)
