• Function

These parameters can be used as brake sequences for lifts and similar equipment.

To ensure smooth operation, the motor produces enough torque before the brake is released.

In case of setting ￿￿￿￿#0.00, braking sequence function with current monitor can be used via the cooperation of ￿￿￿￿ with low current detection. After exciting forcing and ￿￿￿￿, Only in case of load current is bigger than low current detection level (￿￿￿￿($￿￿￿￿)), braking release output (output terminal function 68 (positive logic) / 69 (negative logic) will be output.
