Braking Power
February 2002
In this strategy, the braking ramp to be used in an emergency stop is entered.
Set the axis braking ramp for an emergency stop:
7 Enter as a minimum value in
7 Use the emergency stop to brake the axis from rapid traverse.
7 Increase the value entered in MP2590.x until the braking time is as short as
possible and the mechanics of the axis are not overloaded.
If the value entered is too small, i.e. if braking is too slow, the axis brakes at
the acceleration defined in MP1060.x.
Note
The value entered in MP2590.x refers to the motor speed, meaning the
ballscrew pitch is not considered.
MP2590.x Braking ramp in an emergency stop
Input: 0.1 to 999.9 [rpm/ms]
0: Function inactive
In this strategy the maximum braking power for braking the spindle/spindles
in an emergency stop or power failure is entered.
If power limiting (MP2392.x) is used in normal operation, then the maximum
braking performance is limited to the lower of the two values from the power
limiting and the braking power.
Example:
