Pr.80 External input signal selection
Set whether to use "external input signal of QD77MS", "external input signal of
servo amplifier", or "buffer memory of QD77MS" as "external input signal
(upper/lower limit signal, near-point dog signal)".
0: External input signal of QD77MS
QD77MS2 QD77MS4
1: External input signal of servo amplifier
2: Buffer memory of QD77MS
3: External input signal 1 of QD77MS
QD77MS16
4: External input signal 2 of QD77MS
QD77MS16
5: External input signal 3 of QD77MS
QD77MS16
6: External input signal 4 of QD77MS
QD77MS16
POINT
(1) If "2: Buffer memory of QD77MS" is set, operation is affected by the PLC scan
time.
(2) If "3" to "6" is set in the QD77MS2/QD77MS4, "External signal selection error"
(error code: 936) will occur when the PLC READY signal [Y0] is turned ON, and
the QD77 READY signal [X0] will not be turned ON. Set "0" to use the external
input signal of QD77MS2/QD77MS4.
(3) If "0" is set in the QD77MS16, "External signal selection error" (error code: 936)
will occur when the PLC READY signal [Y0] is turned ON, and the QD77
READY signal [X0] will not be turned ON. Set "3" to "6" to use the external input
signal of QD77MS16.
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.
