Description
communication
6: Ethernet communication
7: High-speed pulse HDIB
8: EtherCat/Profinet communication
9: Programmable extension card
10: Reserved
Note: The reference channel and feedback
channel cannot overlap; otherwise, PID cannot be
controlled effectively.
0: PID output is positive characteristic: namely, the
feedback signal is larger than the PID reference,
which requires the VFD output frequency to
decrease for PID to reach balance, for example,
tension PID control of winding
1: PID output is negative characteristics: namely
the feedback signal is less than PID reference,
which requires VFD output frequency to increase
for PID to reach balance, for example, tension PID
control of unwinding.
This function code is suitable for proportional gain
P of PID input.
It determines the regulation intensity of the whole
PID regulator, the larger the value of P, the
stronger the regulation intensity. If this parameter
is 100, it means when the deviation between PID
feedback and reference is 100%, the regulation
amplitude of PID regulator (ignoring integral and
differential effect) on output frequency command is
the max. frequency (ignoring integral and
differential actions).
Setting range: 0.00–100.00
It determines the speed of integral regulation
made on the deviation between PID feedback and
