The gain factor is used to increase the control amplification. It makes the controller respond to deviĆ
ations more strongly and faster. If this factor is increased too much, the valve starts to hum. This
occurs especially with static force setpoints and with standstill control. This humming can be reĆ
duced by varying the filter amplification or reducing the amplification.
1)
Force control is not permissible with semi−rotary drives. However, the parameter is used for standĆ
still control.
o
The parameter value cannot be changed.
o
Writing permissible only in commissioning/parametrising mode with disabled controller.
ý
This parameter can be written by FCT without higher−order controller.
ý
After writing, controller recalculation is carried out.

Dynamic amplification is only effective in the area of the force ramp, in other words when the force
setpoint changes. This parameter is suitable for improving the truth to path in the area of the ramp,
when amplification cannot be further optimized.
