If the zero pulse has already occurred once or the absolute value encoder (e.g. resolver) is used as
actual value encoder, the drive traverses as described in Fig. 8-12 Approaching … via the set ramp
to its home position.
Acceleration a nd deceleration time
The deceleration and acceleration time refers to a change of the output value from 0 to 100%
(C0011). The time C0936 to be set can be calculated as follows:

In this case the time desired for the change lies between w

The calculated time is to be entered into C0936.
