C27 Skip frequency 1 (Hz) : 00.0
–200
C28 Skip frequency 2 (Hz) : 00.0
–200
C29 Skip frequency range (± Hz) : 00.0
–30.0
Example: C27=10.0Hz / C28=20.0Hz / C29=02.0Hz
±2Hz= 8-12Hz
10Hz 20Hz ±2Hz=18-22Hz Skip frequencies
C30 =1: D is the deviation of PID error in the unit time (C34).
=2: D is the deviation of feedback value in the unit time (C34).
=3: D is the deviation of PID error in the unit time (C34). When the deviation is positive, the output
frequency decreases, and vice versa.
=4: D is the deviation of feedback value in unit time (C34).When the deviation is positive,
the output frequency decreases, and vice versa.
C31 PID Error gain : 0.00 - 10.0
C31 is PID error gain, and the feedback value = feedback value × C31.
C32 P: Proportional gain : 0.00 - 10.0
C32: Proportional gain for PID control.
C33 I: Integral time (s) : 00.0
– 100
C33: Integral time for I control (
NOTE:
To
increase
integral action,
decrease
the integral time
setting.)
C34 D: Differential time (s) : 0.00 - 10.0
C34: Differential time for D control.
C30 PID operation mode
(See Fig. 11.13)
000: PID Function disabled
001: PID Control, Deviation is derivative controlled
002: PID Control, Feedback is derivative controlled
003: Same as 001 but (reverse characteristics control)
004: Same as 002 but (reverse characteristics control)
