Braking the axes by

additional braking

spindle/spindles by

entering the

braking power

In this strategy, the braking ramp to be used in an emergency stop is entered.

Set the axis braking ramp for an emergency stop:

Enter as a minimum value in

Use the emergency stop to brake the axis from rapid traverse.

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.

Once the value for MP2590.x has been determined and entered, the braking

process at this setting must be checked. You must ensure that simultaneous

braking of all axes does not lead to a switch-off due to overload of the

inverters. The nearer the determined braking ramp is to the emergency stop

ramp, the greater the resulting load on the inverters is.

The value entered in MP2590.x refers to the motor speed, meaning the ball

screw pitch is not considered.

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.
