: PID Set Point Selection,
S
2
: Proportional Gain P,
S
3
: Integral Time I,
S
4
:
Derivative control D
2.
This command FPID can control the PID parameters of the AC motor drive
directly, including Pr.08.00 PID set point selection, Pr.08.01 Proportional gain
(P), Pr.08.02 Integral time (I) and Pr.08.03 Derivative control (D)
Example
1.
Assume that when M0=ON,
S
1
is set to 0 (PID function is disabled),
S
2
=0,
S
3
=1
(unit: 0.01 seconds) and
S
4
=1 (unit: 0.01 seconds).
2.
Assume that when M1=ON,
S
1
is set to 0 (PID function is disabled),
S
2
=1 (unit:
0.01),
S
3
=0 and
S
4
=0.
3.
Assume that when M2=ON,
S
1
is set to 1(frequency is inputted by digital
keypad),
S
2
=1 (unit: 0.01),
S
3
=0 and
S
4
=0.
4.
