Note An open-collector output interface is used for sequence outputs (maximum operating
voltage: 30 VDC; maximum output current: 50 mA).

Output Ground Ground common for sequence outputs (pins 9, 10, 11, and
Common 12).
Ground Common for Encoder output and phase-Z output (pin 21).
Common
These signals output encoder pulses according to the
Encoder
Encoder Dividing Ratio Setting (Pn44).
Phase-A Output
This is the line-driver output (equivalent to RS-422).
Encoder
Phase-B Output
Encoder
Phase-Z Output
Outputs the phase Z for the Encoder (1 pulse/rotation).
Phase-Z Output
This is the open-collector output.
