When connecting an encoder, +5V must be supplied from the drive unit side.
Power does not need to be supplied from the NC(PC) side.

(Note 1) The figure above indicates the case of unipolar input. (Bipolar input cannot be created only with the power supply from the
drive unit side.)
(Note 2) +15V power supply is output from the input pin A (RP, OR3) via the resistance.
(Note 3) Input voltage tolerable value of the input pin B (SE1, OR2) is as follows.
SE1: ±12V
OR2: 0 to +12V
(Note 4) Make sure to use a shielded cable for the cable connecting to each input pin and provide with shield treatment.

2-6-2 Output interface
(1) External contact output circuit
The drive unit fault output signal FA(CN12-10) and FC(CN12-20) are the outputs.
Use the contacts with the rating indicated below.
24VDC 0.3A or less
Chattering 5ms or less
Compact relay is used. When connecting an inductive load such as relay, preferably use a DC
compact relay, and connect a flywheel diode in parallel with the coil as shown in the figure below.

(Note 1) When using a DC relay externally, connect a flywheel diode in parallel with the coil.
(Note 2) 24V and RG are common for the open emitter and open collector output. Pay attention to the cable size. (24V and RG
consume 60mA only for the spindle drive unit internal circuit.)
(Note 3) When all 8 circuits are used for the open emitter output, the total current has to be no more than 350mA.
(Note 4) High-frequency noise due to chopper affect s this output signal and may cause the reception side of circuit for this signal to
malfunction. In such a case, use a shielded cable for the output signal connection cable, and connect one side of the
shielded cable to the spindle drive unit CN10-10 pin and the other one to the 24V power supply's ground.
(4) Pulse feedback output
Pulse feedback output is described as shown in the figure below.
(The output signal is equivalent of RS485.)
