7.6.12 Setting the brake control
The following actions take place after specifying a travel command :
1. The firing pulse and the controller are enabled
2. The “Release brake” signal is output
3. The ramp-function generator starts to ramp up
•
P087 (with a negative value) can be used to delay the “Release brake” signal in relation to the
enabling of the firing pulse and the controller until the motor has definitely been excited and
torque has developed.
•
Parameter P319 can be used to delay the ramping up of the ramp-function generator in relation
to the enabling of the firing pulse and the controller using until the brake has definitely been
released (no start-up with brake still closed).
