16.5.3.1 Limitation of Speed Controller
The output signal of the speed controller is the torque-forming current component
Isq. The output and the I component of the speed controller can be limited via para-
meters

740. The limits of the proportional component are set via parameter
P
component torque upper limit
732 and parameter
P component torque lower limit
733 .

The output value of the controller is limited by an upper and a lower current lim-
it, parameter

.
The limit figures are entered in Amperes. The current limits of the con-
troller can be linked to the fixed limits and analog input parameters. The assign-
ment is done via the parameters

731. The limit values are input as a percentage of the rated motor torque.
The assignment of fixed values or analog limit values is done via the parameters
Torque limit source, motor op.
736 and
Torque limit source, generator op.
737.
−
The output value of the P component is limited with parameter
P comp. torque
upper limit
732 and
P comp. torque lower limit
733
. The limit values are input
as torque limits as a percentage of the rated motor torque.
− The power output by the motor is proportional to the product of speed and tor-
que. This output power can be limited at the controller output with

740. The power limits are entered in
kW.
