Stop!

Only carry out a TRIP reset via the fieldbus!
The drive might start running for a short period if a fault is reset via
terminal 28 while the controller is being operated with fieldbus control
(C0001 = 3) and has assumed the device status "FAULT".

If the setpoint and the direction of rotation are changed simultaneously via
the DRIVECOM speed setpoint, a speed change in the wrong direction of
rotation may occur for a short time.
For this reason always send a low rotation direction setpoint first, followed
by the new setpoint if the direction of rotation is changed.
This is because first the setpoint is sent to the controller as a unipolar value,
followed by the information on the change of the rotation direction.

The X controller is initialised after the "fault reset" command. During this time the
controller does not accept any other commands.
