3. Controller Functions
3.7 Speed Controller Functions
When changing the speed or changing the operating mode of the drive
from the main spindle to the C-axis servo function, different mechanical
systems make different demands on the speed controller.
Four diferent parameter records, which can be called up via control
inputs, are available. Specified speed control parameters are in each of
these parameter records for the appropriate mechanical coupling or
operating mode.
Because of the wide speed range, the main spindle drive operates in the
constant torque or constant power range regardless of speed. This also
requires the speed controller to be changed over according to the speed.

Note:
The motor is sufficiently magnetized and can provide the full torque only
200 ms after the controller enabling signal (RF = 1). The command value
is inhibited during this interval.
If the controller enabling signal (RF) switches to 0 while the drive is
turning, then the drive will brake at a set ramp until it reaches the zero
velocity and only then becomes torque-free. If neither a ramp nor torque
reduction are set, then the drive will brake at maximum torque!
