Setting Absolute Linear Scale; Setup Procedure - YASKAWA Σ-V Series User Manual

Setting Absolute Linear Scale

The Σ-V SERVOPACK is compatible with an absolute linear scale.
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 linear servomotor to overrun and may result in injury or damage to the
product.

4.5.1 Setup Procedure

Step
Perform all necessary wiring and set the required safety
1
function.
Turn ON the SERVOPACK and confirm that the SERVO-
2
PACK operates correctly.
Write the motor parameters and the scale constants into
3
the absolute linear scale using the specified tool.
4
Perform origin setting (Fn020).
5
Perform polarity detection (Fn080).
6 Turn the power supply OFF and then ON again.
7 Perform polarity detection (Fn080).
∗1. This step can be skipped in the following cases.
• After setting the origin for the absolute linear scale itself
• After replacing only the SERVOPACK
∗2. Perform this step only when the linear 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 linear servomotor.
∗3. When using a linear scale manufactured by Magnescale Co., Ltd., this procedure is not necessary.
