For example:
If A=2 and B=0, i.e. P1-46 is set to 2, and P1-61 is set to 7 (Default), the pulse numbers of
encoder outputs per motor revolution =

It indicates that the encoder will output 500 pulses per motor revolution.
NOTE
1) The default setting of parameter P1-61 is 7.
2) The max. frequency for pulse output is 500Kpps.

• A=0: Forward homing (CCWL as “Home”)
• A=1: Reverse homing (CWL as “Home”)
• A=2: Forward homing (ORGP as “Home”)
• A=3: Reverse homing (ORGP as “Home”)
• A=4: Forward to find Z-phase pulse and regard Z-
phase pulse as “Home”
• A=5: Reverse to find Z-phase pulse and regard Z-
phase pulse as “Home”
• B=0: Return to find Z-phase pulse during homing
• B=1: Do not return and go forward to find Z-phase pulse during homing
• B=2: Positioning at home sensor position or Z-phase pulse during homing (it only can be
used when A=2, 3, 4 or 5)
• C=0: Disable homing function.
• C=1: Enable homing function automatically after power supplies to the servo drive.
