Setting example
The following shows an example for setting an incremental synchronous encoder as
synchronous encoder axis 2 of the QD77MS.
QD77MS
Set "1: Incremental synchronous encoder" in "[Pr.320] Synchronous encoder axis type" for
the synchronous encoder axis 2.
And, set the input method for incremental synchronous encoder signal in the following
parameters.
• "[Pr.22] Input signal logic selection" Manual pulse generator input (b8)
................................................................... "0: Negative logic"
• "[Pr.24] Manual pulse generator/Incremental synchronous encoder input selection"
..........................................................................
• "[Pr.89] Manual pulse generator/Incremental synchronous encoder input type selection"
................................................................... "0: Differential output type"
