 S
1
: PID reference target value input terminal selection. S
2
: PID function
proportional gain P. S
3
: PID function integral time I. S
4
: PID function differential
time D.
 The FPID command can directly control the drive’s PID feedback control Pr.08-
00 Terminal Selection of PID Feedback, Pr.08-01 Proportional Gain (P), Pr.08-02
Integral Time (I), and Pr.08-03 Differential Time (D).
 When M0=ON, the set PID reference target value input terminal selection is 0 (no
PID function), the PID function proportional gain P is 0, the PID function integral
time I is 1 (units: 0.01 sec.), and the PID function differential time D is 1 (units:
0.01 sec.).
 When M1=ON, the set PID reference target value input terminal selection is 0 (no
PID function), the PID function proportional gain P is 1 (units: 0.01), the PID
function integral time I is 0, and the PID function differential time D is 0.
 When M2=ON, the se
t PID reference target value input terminal selection is 1
(target frequency input is controlled through the digital keypad), the PID function
proportional gain P is 1 (units: 0.01), the PID function integral time I is 0, and the
PID function differential time D is 0.
