SIMOREG DC Master Operating Instructions
9.16 Speed-dependent current limitation
The speed-dependent current limitation protects the commutator and brushes of the DC motor at high
speeds.
The necessary parameter settings (P104 to P107) can be taken from the motor rating plate.
The maximum operating speed of the motor (P108) must also be entered. This must be the same as
the actual maximum operating speed.
The actual maximum operating speed is determined by:
−
P143 with actual speed supplied by a pulse encoder,
−
P741 with actual speed supplied by an analog tacho,
−
P115 in operation without a tachometer.
Furthermore, the speed-dependent current limitation must be activated by setting P109 = 1!
CAUTION
Setting the speed-dependent current limitation function to the wrong value may cause excessive
loading of the commutator and brushes, resulting in a drastic reduction in brush life!
