6.10.4 Changing the direction of rotation
In the basic configurations (C0005) the direction of rotation of the motor is
reversed in a fail−safe way via the X5/E1 and X5/E2 and the function block
R/L/Q. Thus, only the main setpoint is changed.
The reversing time depends on the ramp times set for the main setpoint or
quick stop.
When the direction of rotation is changed, the drive brakes along the
deceleration ramp (C0013) and accelerates along the acceleration ramp
(C0012) into the other direction of rotation.

Unchanged HIGH HIGH l During operation: The direction
of rotation results from the signal
which was active first.
l At mains connection: The
controller activates quick stop
(QSP).
