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.
