Name and function
Explanation
For manufacturer setting
Load-side encoder communication method
0: Two-wire type
1: Four-wire type
Setting "1" by using a servo amplifier other than MR-J4-_B_-RJ will
trigger [AL. 37].
Explanation
Encoder pulse count polarity selection
0: Encoder pulse increasing direction in the servo motor CCW or
positive direction
1: Encoder pulse decreasing direction in the servo motor CCW or
positive direction
For manufacturer setting
Selection of A/B/Z-phase input interface encoder Z-phase
connection judgement function
This is used to select a non-signal detection of A/B/Z-phase input
interface encoder pulse train signal used as linear encoder or load-
side encoder.
This digit is enabled only when you use an A/B/Z-phase input
interface encoder.
