(Special input: 3 points, general-purpose input: 12 points, multi-points orientation command: 12
points, digital speed command: 12 points)

(Note 1) A +24V(±10%) power supply is required for this unit. The required maximum power supply capacity is 26W. DC stabilized
power supply must be used here.
(Note 2) Common for dedicated/general-purpose input is CES1, common for digital speed command is CES2, and common for
multi-point orientation command is CES3. Each command is electrically separated one another.
Thus, when using CES1, 2 or 3, each of them has to be connected to one of the signals (power supply, etc.).
(Note 3) Filter time constant at the input section is 5 to 15ms.
(Note 4) When running the motor on a trial basis, (when only "machine ready complete", "forward run" and "reverse run" are input
and all the other 24V I/O are not used.), external +24V power supply is exceptionally not necessary; internal +24V power
supply will do. In this case, use CN10-7 pin for +24V, CN10-10 pin for RG (24G).
(Note 5) Power supply unit's CN23 is a similar circuit; however, the resistance is not 4.7kΩ but 2kΩ.

(2) Encoder (1024p/rev) input interface
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.

(Note 5) If there is a separate analog speed input command (or override input) power supply, connection will be as shown below.

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.
