p50108[0...n] Speed-dependent current limitation maximum operating speed n3 / I_lim n_dep n3
DC_CTRL Can be changed: C2(1), U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
1 [1 rpm]
Description: Sets the maximum operating speed n3 for "speed-dependent current limitation".
Dependency: Refer to: p50104, p50105, p50106, p50107, p50109
Note: In this parameter, the following maximum speed must be set dependent upon the setting of the signal source for the
speed actual value (p50083):
- p50083 = 1 (analog tachometer): Speed prevailing at a tachometer voltage according to p50741
- p50083 = 2 (incremental encoder TTL/HTL): Same value as maximum speed according to p50143
- p50083 = 3 (operation without tachometer): Speed prevailing at an EMF according to p50115.

Armature circuit resistance / Ra

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.000 [ohm]
Description: Sets the armature circuit resistance.
Note: The parameter is set automatically during the optimization run for pre-control and the current controller for the
armature converter (p50051 = 25).

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.000 [mH]
Description: Sets the armature circuit inductance.
Note: The parameter is set automatically during the optimization run for pre-control and the current controller for the
armature converter (p50051 = 25).
