should be calculated from all of the feed axes
and main spindles that are simultaneously operated. This calculated power
must be less than the peak power of the regenerative feedback module.
1.3.3 Braking operation
With the UI modules, only deceleration with pulsed resistors is possible.
With I/R modules, a regenerative feedback of excess energy to the supply
system also occurs. For required braking operations in the event of a power
failure, the braking module and pulsed resistors are also needed.
The regenerative feedback power is dependent on the available energy to be
braked in the system:
S The mass
S Speed/velocity
S Braking ramps/braking time
S Efficiencies
