Parameter 14-30 Current Lim Ctrl, Proportional Gain
Table 722: Parameter 14-30 Current Lim Ctrl, Proportional Gain
14-30 Current Lim Ctrl, Proportional Gain
Default value: 100%
Parameter type: Range, 0 - 500%
Setup: All setups
Conversion index: 0
Data type: Uint16
Change during operation: False
Enter the proportional gain value for the current limit controller. Selection of a high value makes the controller react faster. Too high
a setting leads to controller instability.
Parameter 14-31 Current Lim Ctrl, Integration Time
Table 723: Parameter 14-31 Current Lim Ctrl, Integration Time
14-31 Current Lim Ctrl, Integration Time
Default value: Size related
Parameter type: Range, 0.002 - 2 s
Setup: All setups
Conversion index: -3
Data type: Uint16
Change during operation: False
Controls the current limit control integration time. Setting it to a lower value makes it react faster. A setting too low leads to control-
ler instability.
Parameter 14-32 Current Lim Ctrl, Filter Time
Table 724: Parameter 14-32 Current Lim Ctrl, Filter Time
14-32 Current Lim Ctrl, Filter Time
Default value: Size related
Parameter type: Range, 1 - 100 ms
Setup: All setups
Conversion index: -4
Data type: Uint16
Change during operation: True
Controls the current limit control low-pass filter. This makes it possible to react to peak values or to average values. When selecting
average values, it is sometimes possible to run with higher output current and instead trip on the hardware limit for current. Howev-
er, the control reacts slower as it does not react on immediate values.
Parameter 14-33 Torque Change Detection
Table 725: Parameter 14-33 Torque Change Detection
14-33 Torque Change Detection
Default value: [0] Disabled
Parameter type: Option
Setup: All setups
Conversion index: -
Data type: Uint8
Change during operation: True

Use this function in VVC+, flux, and in speed mode. The torque load is minimum 15% of nominal torque and
the actual speed equals to the reference. Parameter 14-39 Torque Change Threshold Limit is used for thresh-
old limit generation.
Parameter 14-34 Stall Protection Adjustment Factor
Table 726: Parameter 14-34 Stall Protection Adjustment Factor
14-34 Stall Protection Adjustment Factor
Default value: 100%
Parameter type: Range, 50 - 200%
Setup: All setups
Conversion index: -4
Data type: Uint16
Change during operation: True
