The profile generator generates ramps which lead the setpoint phase to its target position.
•
Set acceleration and deceleration via C0751.
•
Set max. speed via C0752.
•
When distance and speed reach their setpoints, the output switches DFRFG1-SYNC = HIGH.

Fig. 7-137 Speed-time diagram DFRFG
The number of increments at DFRFG-IN (master drive) defines the target position. The target can be
displayed as a path. The speed-time diagram shows the distance covered (angle) as the area below
the speed profile. When synchronisation is reached, master and slave have covered the same
distance (phase).
