14.08

PID enable

Bit SP
Coding
1
Range OFF(0) or On(1)
Default OFF(0)
Update rate 21 ms
This parameter must be at On(1) for the PID controller to operate, if it is OFF(0) the PID output will be 0.
14.09

Optional PID enable source

Bit SP
Coding
Range Pr 0.00 to Pr 21.51
Default Pr 0.00
Update rate Read on drive reset
To enable the PID controller the drive must be ok (Pr 10.01 = On) and the PID enable (Pr 14.08) must be set to On(1). If the optional enable source
(Pr 14.09) is 00.00 or routed to a non-existent parameter the PID controller is still enabled provided Pr 10.01 = On and Pr 14.08 = On. If the optional
enable source is routed to an existing parameter the source parameter must be On before the PID controller can be enabled. If the PID controller is
disabled the output is zero and the integrator is set to zero.
14.10

PID proportional gain

Bit SP
Coding
Range 0.000 to 4.000
Default 1.000
Update rate 21 ms
This is the proportional gain applied to the PID error.
14.11 PID integral gain
Bit SP
Coding
Range 0.000 to 4.000
Default 0.500
Update rate 21 ms
This is the gain applied to the PID error before being integrated.
14.12 PID derivative gain
Bit SP
Coding
Range 0.000 to 4.000
Default 0.000
Update rate 21 ms
This is the gain applied to the PID error before being differentiated.
14.13 PID high limit
Bit SP
Coding
Range 0.0 to 100.0%
Default 100.0
Update rate 21 ms
