SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013

Description: Sets the proportional gain (P component) of the technology controller.

Note: p2280 = 0: The proportional gain is disabled.

Description: Sets the integral time (I component, integrating time constant) of the technology controller.

Notice: The following applies for p2251 = 0:

If the output of the technology controller lies within the range of a suppression (skip) bandwidth (p1091 ... p1094,

p1101) or below the minimum speed (p1080), the integral component of the controller is held so that the controller

temporarily works as a P controller. This is necessary in order to prevent the controller from behaving in an unstable

manner, as the ramp-function generator switches to the parameterized up and down ramps (p1120, p1121) at the

same time in order to avoid setpoint steps. This state can be exited or avoided by changing the controller setpoint or

by using the start speed (= minimum speed).

Note: When the controller output reaches the limit, the I component of the controller is held.

p2285 = 0:

The integral time is disabled and the I component of the controller is reset.

Description: Sets the signal source to hold the integrator for the technology controller.

Description: Sets the signal source for the pre-control signal of the technology controller.

Description: Sets the maximum limit of the technology controller.

Dependency: Refer to: p2292
