Multistep PID Command
• Multistep PID Command 1 to 3 (3024Hex-25Hex, 3024Hex-26Hex, 3024Hex-27Hex)
The PID command value can be applied by the multi-step command of digital input. To use this func-
tion, allocate "171: PID-SS1" and "172: PID-SS2" to Input Terminal [DI1] to [DI7] Function Selection
(3005Hex-02Hex to 3005Hex-06Hex, 3005Hex-63Hex, 3005Hex-64Hex).

Anti-reset Windup
• PID Control Anti-reset Windup Width (300EHex-0BHex)
Restrains overshooting during control by a PID controller. If the difference 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 (%)

PID Output Limiter
It is possible to set a limiter for the upper limit and lower limit in the PID output exclusively for PID
control. The limiter is disabled when PID cancellation "Hz/PID" is entered and operation is performed
at the normal frequency setting.
• PID Control PID Output Upper Limit (300EHex-13Hex)
The upper limit value for the limiter of PID controller output is set in percentage. If the set value is
specified as 999, the settings of 1st Frequency Upper Limit (3004Hex-10Hex) are followed.
• PID Control PID Output Lower Limit (300EHex-14Hex)
The lower limit value for the limiter of PID controller output is set in percentage. If the set value is
specified as 999, the settings of 1st Frequency Lower Limit (3004Hex-11Hex) are followed.
