Operands:
S1: PID Set Point Selection(0-4), S2: Proportional gain P (0-100), S3: Integral Time I (0-10000), S4:
Derivative control D (0-100)
Explanation:
1.
This command FPID can control the PID parameters of the AC motor drive directly,
including Pr.10.00 PID set point selection, Pr.10.02 Proportional gain (P), Pr.10.03
Integral time (I) and Pr.10.04 Derivative control (D)
Program Example:
1.
Assume that when M0=ON, S1 is set to 0 (PID function is disabled), S2=0, S3=1 (unit:
0.01 seconds) and S4=1 (unit: 0.01 seconds).
2.
Assume that when M1=ON, S1 is set to 0 (PID function is disabled), S2=1 (unit: 0.01),
S3=0 and S4=0.
3.
Assume that when M2=ON, S1 is set to 1(frequency is inputted by digital keypad), S2=1
(unit: 0.01), S3=0 and S4=0.
