6.8.2 Interpolator
Schematic of the Interpolator:
The interpolator calculates a velocity from the programmed feed rate. In the
CC 6xxx it makes this calculation every 3 ms. The value is also dependent on
the acceleration curve and the end position.
If more than one axis is moved simultaneously, the path acceleration a
path
is
formed from the appropriate axis components. The same applies to rapid
traverse in the path (see "Rapid traverse and feed rate limiting" on page 839).
If the inverter is not designed for such accelerations, you can limit the path
acceleration:
 In MP1061.0, enter the maximum permissible path acceleration for the
machining feed rate.
 In MP1061.1, enter the maximum permissible path acceleration for the rapid
traverse.
This division enables you to enter a lower value for the acceleration at
machining feed rate, which makes it possible to optimize the behavior of
drives with regard to backlash compensation.
