Setting the Zero Point for a Finite Length Mode Axis

Set the zero point as described here after initializing the absolute encoder to set the zero
point of the machine coordinate system and to establish the machine coordinate system.

The following illustration shows the procedure for setting the zero point for a Finite Length
Mode Axis.

∗ 1.

The OLC006 value must be saved when it is set.

∗ 2.

See the information on the next page for more details on saving the

OLC006 value.

∗ 3.

Execute with the ZSET command.

Start

Servo ON

JOG to move close to

the zero point.

STEP to move to the

zero point.

• OLC006 = -(ILC002) + OLC006 *1
• Save OLC006 *2

Set the zero point.*3
