Chapter 5 Data Used for Positioning Control
Pr.80
External input signal selection
Set whether to use "external input signal of servo amplifier" or "buffer memory of
LD77MS" as an external input signal (upper/lower limit signal or near-point dog
signal)".
1: External input signal of servo amplifier
*1
2: Buffer memory of LD77MS
1: At MR-JE-B use, refer to Appendix 6.5 "Connection with MR-JE-B".
POINT
(1) When other than "1: External input signal of servo amplifier" and "2: Buffer
memory of LD77MS" is set, the error "External input signal selection error"
(error code: 936) occurs at turning the PLC READY signal [Y0] ON, and the
READY signal [X0] is not turned ON.
(2) When "2: Buffer memory of LD77MS" is set, operation is affected by the PLC
scan time.
Pr.24
Manual pulse generator/Incremental synchronous encoder input
selection
Set the manual pulse generator/incremental synchronous encoder input pulse
mode. (Only the value specified against the axis 1 is valid.)
0: A-phase/B-phase multiplied by 4
1: A-phase/B-phase multiplied by 2
2: A-phase/B-phase multiplied by 1
3: PLS/SIGN
Set the positive logic or negative logic in "
Pr.22
Input signal logic selection
".
(1) A-phase/B-phase mode
• When the A-phase is 90° ahead of the B-phase, the motor will forward run.
• When the B-phase is 90° ahead of the A-phase, the motor will reverse run.
(a) A-phase/B-phase multiplied by 4
The positioning address increases or decreases at rising or falling edges
of A-phase/B-phase.
