Process for homing to fixed stop

In order for homing to fixed stop to function, the position lag monitor in the drive must be disabled or the limit value must be set to a higher setting. In addition , the maximum torque of the drive must be limited.

This is achieved by writing the drive parameters to the drive. The detection criteria are checked during homing. The criteria consist of the position lag, velocity and drive torque and can be used singly or in combination to detect the fixed stop. When the fixed stop is detected, the actual position sent by the drive is transferred to the CNC. The axis is then moved away from the fixed stop by the retraction distance parameter.

Notice

Axis position after homing

After homing is complete, the axis is not located at its reference point. This is due to the retraction distance that is retracted after the fixed stop is reached.
