I/O Signals Of Slave Axis; Data Used For Positioning Control Of Slave Axis - Mitsubishi Electric QD77MS User Manual

(4) I/O signals of slave axis

(a) Input signal
[QD77MS2]
Only the error detection signal [X8, X9] is valid. And only the servo
alarm detection is valid. (The control of slave axis is not influenced even
if the error other than servo alarm has been occurred.)
[QD77MS4]
Only the error detection signal [X8 to XB] is valid. And only the servo
alarm detection is valid. (The control of slave axis is not influenced even
if the error other than servo alarm has been occurred.)
[QD77MS16]
All signals cannot be used. The error detection signal turns ON "Error
detection" ([Md.31]
(b) Output signal
All output signals of slave axis cannot be used.

(5) Data used for positioning control of slave axis
