2.3 Reference Returning

The control of the Machine motion is based on the establishment of

coordinate system . Therefore, after the system is reset, each machine

axis must return to the reference point. Follow the instructions below:

1.

If the currently operation mode is not Home Return, press the

Reference Return button on the control panel to make sure that the

system is in the Home Return mode.

2.

Based on the X-axis machine parameter of REF Direction, press X

and the direction key (the value of REF Direction is "+"). After the

X- axis returns to the reference point, the indicator of the X key is

on.

3.

Return the Z axis to the reference point with the same method.

4.

After return every axes to the reference point, the machine

coordinate system is established.

Attention

1.

Return all axes to the reference point as soon as the power is on in

order to ensure the axis coordinate is correct. After that, other

operations can be performed.

2.

Press the direction keys of X, Y, and Z simultaneously to return the

three axes to the reference point at the same time.

3.

Before returning the axis to the reference point, make sure that the

axis is in the opposite direction of REF Direction (e.g. if the REF

Direction of the X axis is "-", then make sure the X axis direction is

"+" before returning it to the reference point); otherwise, manually

move the axis until it meets the requirement.

4.

When returning axis to the reference point, if over-travel occurs,

press the over-travel release key on the control panel and manually

move the axis in the opposite direction to exit the over-travel status.

5.

After return each axis to the reference point, the reference return

doesn’t need to be performed again (including alarms and pressing

the Emergency Stop button ) unless a servo drive device alarm is

reported.

6.

When returning axis to the reference point, if the Reset key is

pressed before the Reference Returning key is pressed, the home

returning will be canceled.
