Service use only.
Table 244: Range:

4.11.4 14-3* Current Limit Ctrl.
Parameters for configuring the current limit controller, which is activated when the motor current exceeds the preset current limits
(see parameter 4-18 Current Limit). These parameters are used to reduce torque as quickly as possible without losing control of the
motor.
14-30 Current Lim Ctrl, Proportional Gain
Default value: 100%
Conversion index: 0
Enter the proportional gain value for the current limit controller. A higher value makes the controller react faster. Excessive value
setting leads to controller instability.
Table 245: Range:
Min: 0%
14-31 Current Lim Ctrl, Integration Time
Default value: 0.020 s
Conversion index: -3
Control the current limit control integration time. Setting it to a lower value makes it react faster. A setting too low leads to control
instability.
Table 246: Range:
Min: 0.002 s
14-32 Current Lim Ctrl, Filter Time
Default value: 26.0 ms
Conversion index: -1
Set a time constant for the current limit controller low-pass filter. A shorter period makes the control react faster to changes in cur-
rent.
Table 247: Range:
Min: 1 ms
4.11.5 14-4* Energy Optimization
Parameters for adjusting the energy optimization level in both variable torque (VT) and automatic energy optimization (AEO) mode.
Automatic energy optimization is only active if parameter 1-03 Torque Characteristics is set to [3] Auto Energy Optim.
14-40 VT Level
Default value: 90%
