Identification Of Reference Point Position - BONFIGLIOLI ACTIVE CUBE Applications Manual

5.3.1

Identification of reference point position

When the frequency inverter is switched on during commissioning, the current position of the spindle
is identified by a search mode. The search mode continues for three revolutions at the set frequency

If the motor has already turned before release of axle positioning, the frequency inverter knows the
position of the reference point. In this case, positioning is carried out based on the

In the case of a standing machine, the positioning
operation starts with clockwise rotation.
Clockwise rotation. Homing and positioning will always
start with clockwise rotation in the case of a standing
machine.
Anticlockwise operation Homing and positioning will
always start with anticlockwise rotation in the case of
a standing machine.
