The profile generator generates ramps which lead the setpoint phase to its target position.

l Set acceleration and deceleration via C0751.

l Set max. speed via C0752.

l When the distance and speed reach their setpoints, the output switches

DFRFG1−SYNC = HIGH. At the same time the FB switches the profile generator to "inactive".

l Set the switching point via C0755.

Fig. 3−67 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 synchronicity is reached, master and slave have covered the same distance

(angle).
