he optimization of the speed controller can be done with the help of a reference value leap. The
amount of the leap is defined by the set ramp or limitation. The optimization of the PI controller
should be done at the maximum admissible reference figure change rate. First, the amplification is
increased until the actual value overshoots distinctly during the control process. This is indicated by a
strong os
-c
illation of the speed and by the running noises. In the next step, reduce the amplification
slightly (1/2 ...3/4 etc.). Then reduce the integral time (larger I component) until the actual value
overshoots only slightly in the control process.
I
f necessary, check the speed control settings in the case of dynamic operations (acceleration, decel-
eration). The frequency at which the switch-over of the controller parameters is effected can be set
via parameter
Speed Control Switch-Over Limit 738.
7.9.5.3.1 Limitation of speed controller
The output signal of the speed controller is the torque-forming current component Isq. The output
and the I portion of the speed controller can be limited via parameters
Current Limit 728, Current
Limit Generator Op.
729, Torque Limit 730, Torque Limit Generator Operation 731 or Power Limit
739, Power Limit Generator Operation 740. The limits of the proportional portion are set via param-
eters
P-Comp. Torque Upper Limit 732 and P-Comp. Torque Lower Limit 733.
728 Current Limit
729 Current Limit Generator Op.
The output value of the speed controller is limited by an upper and a lower current limit. From the set
values for
Current limit 728 and Current limit generator operation 729, the limits are calculated,
considering the set magnetizing current. The parameter values are entered in Amperes. The current
limits of the controller can be linked to the fixed limits and analog input parameters. The assignment
is done via the parameters
Isq Limit Source Motor Operation 734 and Isq Limit Source Generator
Op.
735.

The default settings for amplification and integral time refer to the recommended machine data. This enables a
first function test in a large number of applications. Switch-over between settings 1 and 2 for the current fre-
quency range is done by the software ac-cording to the selected limit value.
