Absolute Encoder Home

Position Error Detection

Factory

Setting: 0

For Speed/Torque Control

and Position Control

This memory switch is used to specify whether to use home position error detection
(alarm A.80) when an absolute encoder is used.

Setting

Meaning

0

Detects a home position error.

1

Does not detect a home position error.

Normally, set this memory switch to “0”.

This memory switch has no significance when an incremental encoder is used.

TERMS

Home position error detection

This function detects an encoder count error resulting from noise. It checks the number of
pulses per motor revolution, and outputs a home position error alarm if that number is incor-
rect.
If the absolute encoder detects an error, it inverts phase C and notifies the SERVOPACK of
the error. In this case, this “home position error detection” function also works.
