2302 INTEGRATION TIME 0...600.00 s
Sets the integration time for the speed controller.
• The integration time defines the rate at which the controller output
changes for a constant error value.
• Shorter integration times correct continuous errors faster.
• Control becomes unstable if the integration time is too short.
• The figure shows the speed controller output after an error step
(error remains constant).
Note! You can use parameter 2305,
AUTOTUNE
RUN
, to
automatically set proportional gain.
