CN1-4 The encoder output pulses set in [Pr. PA15] are outputted 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.
CN6-3 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
CN6-2 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% 500 mA) to I/O interface. The power supply
capacity changes depending on the number of I/O interface points to be
CN1-21
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, 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.
CN1-1 This outputs 15 V DC to between P15R and LG. This is available as power
for TC, TLA, VC, or VLA. Permissible current: 30 mA
CN1-3 This is a common terminal for TLA, TC, VC, VLA, FPA, FPB, OP ,MO1,
MO2, and P15R. Pins are connected internally.
