CN1-4 These devices output pulses of encoder output pulse set in [Pr. PA15] in
the differential line driver type.
CN1-5
In CCW rotation of the servo motor, the encoder B-phase pulse lags the
encoder A-phase pulse by a phase angle of π/2.
The relation between rotation direction and phase difference of the A-
CN1-6
phase and B-phase pulses can be changed with [Pr. PC19].
CN1-7
CN1-8 The encoder zero-point signal is outputted in the differential line driver
type. One pulse is outputted per servo motor revolution. This turns on
CN1-9
when the zero-point position is reached. (negative logic)
The minimum pulse width is about 400 μs. For home position return using
this pulse, set the creep speed to 100 r/min. or less.
CN1-33 The encoder zero-point signal is outputted in the open-collector type.
CN1-26 This is used to output the data set in [Pr. PC14] to between MO1 and LG in
terms of voltage.
Resolution: 10 bits or equivalent
CN1-29 This signal outputs the data set in [Pr. PC15] to between MO2 and LG in
terms of voltage.
Resolution: 10 bits or equivalent

CN1-20 Input 24 V DC (24 V DC ± 10% 300 mA) for I/O interface. The power
supply capacity changes depending on the number of I/O interface points
CN1-21
to be used.
For sink interface, connect + of 24 V DC external power supply.
For source interface, connect - of 24 V DC external power supply.
CN1-12 When inputting a pulse train in the open-collector type with sink interface,
supply this terminal with the positive (+) power of 24 V DC.
Common terminal of input signal such as EM2 of the servo amplifier. This
is separated from LG.
CN1-47
For sink interface, connect - of 24 V DC external power supply.
For source interface, connect + of 24 V DC external power supply.
CN1-3 This is a common terminal for TLA, TC, VC, VLA, OP, MO1, and MO2.
Pins are connected internally.
