P gain
This parameter defines the gain of the PID controller. If the value of the
parameter is set to 100%, a change of 10% in the error value causes the
controller output to change by 10%.
PID controller I-time
This parameter defines the integration time of the PID controller. If this
parameter is set to 1,00 second, the controller output is changed by a value
corresponding to the output caused from the gaine very second. (Gain × Er-
ror)/s.
PID controller D-time
This parameter defines the derivative time of the PID controller. If this pa-
rameter is set to 1,00 second, a change of 10% in the error value causes the
controller output to change by 10%.
