Power limit of
spindle
6 – 192
You can limit the power of your spindle motor to get wider gear ranges:
7 7 7 7
In MP2393.x, enter the maximum power for wye and delta connection.
Wide-range motors are characterized by a larger speed range with higher
torque at low speed.
One solution for bringing about this behavior is to use an oversized motor, and
to limit the maximum power. However, power limiting does not reduce the
high torque to the speed at which power limiting becomes effective. This high
torque (until power limiting takes effect) can be reduced with torque limiting,
in order to keep the mechanics of the machine from becoming overloaded.
The torque can be calculated for any speed:
M: Torque
P: Power
n: Speed
Note
MP2393.x can have an effect on the braking of the spindle in an emergency
stop ((See "Spindle with integral DSP " on page 6 – 199)).
