Individual Functions
6-97
Multi-Function Digital Inputs (H1-01 to H1-10)
Multi-Function Analog Input (H3-05, H3-09)
PID Control Methods
There are four PID control methods. Select the method by setting parameter b5-01.
PID Input Methods
Enable PID control using parameter b5-01, and set the PID target value and PID feedback value.
PID Target Value Input Methods
Select the PID control target value input method according to the setting in b1-01 (Frequency Reference
Selection).
Normally, the frequency reference selected in b1-01 is the PID target value, but the PID target value can be
changed as shown in the following table.

Set Value Control Method
1
PID output becomes the MxC output frequency, and D control is used in the difference between PID tar-
get value and feedback value.
2 PID output becomes the MxC output frequency, and D control is used in the PID feedback value.
3
PID output is added as compensation value of the MxC output frequency, and D control is used in the dif-
ference between PID target value and feedback value.
4
PID output is added as compensation value of the MxC output frequency, and D control is used in the
PID feedback value.
PID Target Input Method Setting Conditions
Multi-Function Analog
Terminal A2 Input
Set H3-05 or H3-09 to C (PID target value). Also, be sure to set H6-01 (Terminal RP
Pulse Train Input Function Selection) to 1 (PID feedback value).
The negative inputs cannot be used for target values.
MEMOBUS register 0006H
Set MEMOBUS bit 1 in register address 000FH to 1 to be able to use register number
0006H as the PID target value.
