FM-3 Programming Module Reference Manual

The Specified Offset allows the user to choose an exact offset from the Home Reference.

Once the home reference is detected, the device will do whatever is necessary to reach the

offset position. This may be as simple as a deceleration to a stop, a continuation at speed

followed by a deceleration to a stop, or a deceleration followed by a move in the opposite

direction.

To enter a specified home offset, select the Specified Offset radio button. PowerTools FM-3

always displays the calculated offset value as a reference. If the home reference is detected

before the axis has reached its peak velocity, the axis will still continue to the precise offset

position.

If the Home Reference is detected after the axis has reached its peak velocity, the axis will

decelerate to the precise offset position.
