+A
Encoder phase A+
Encoder signals (or external scale signals during full closing control) are output according En-
coder Dividing Numerator parameter.
This is the line-driver output (equivalent to R422). The maximum output frequency is 4 Mbps.
Phase Z is output for encoder signals (or external scale signals during full closing control). This
is the line-driver output (equivalent to R422).
