Setting Absolute Linear Scale

The Σ-V SERVOPACK is compatible with an absolute linear scale manufactured by Mitutoyo. (Model: ABS
ST78 A)
With an absolute position system using an absolute linear scale, homing is not necessary every time the power
is turned ON, so an immediate start of operation is possible.
• Be sure to correctly set up the absolute position system.
Be sure to set up the system again after the system configuration is altered by changes such as the
replacement of the SERVOPACK, the absolute linear scale, or any of their parts.
Failure to observe this warning may cause the servomotor to overrun and may result in injury or damage to the prod-
uct.

5.9.1 Setup Procedure

Step
∗1. Perform this step only when the servomotor must move from the current position to a position that will be set as the
origin after an electrical current is applied to the servomotor.
∗2. This step can be skipped in the following cases.
• After setting the origin for the absolute linear scale itself
• After replacing only the SERVOPACK
