Page 2: Introduction
The Oriental Motor (OM) CFK Series is a family of 5-Phase Stepping Motor Units which are available in single and double shaft versions. This manual describes the installation and use of the motors in the CFK Series, and instructs you in the precautions you should take when using these devices. -

Installation Installation areas for the motors and drivers should : ・ Be free from water, dust, oil mist, salt or corrosive gas. ・ Be free from excessive vibration or shock. ・ Have good ventilation. ・ Have ambient temperature for: ・... - Page 5 Mounting the Motor There are two motor frame sizes as seen in Figure 2 : CFK54 □ A(B) and CFK56 □ A(B). Panel cutout requirements are shown in Figure 3 and corresponding dimensions and angles are detailed in Table 2. Motors are supplied with single or double shafts. CFK54 □...
- Page 6 Mounting the Driver Figure 4 shows the proper mounting of the driver for horizontal and vertical installation. When mounted horizontally, the heat sink should face upward. A vertical mounting requires that the terminal blocks face upward. For heat sink attachment, use M3-P 0.5 screws. The screw length is 5 mm plus the thickness of the mounting plate.

Page 7: Wiring
4. Wiring Wiring of the CFK motors consists of interconnecting the Driver to the Power Supply via CN1, to the Controller via CN2, and to the Motor via CN3. The Wiring diagram for all connectors is shown in Figure 7. The power and signal connections are detailed in Table 3 on page 8 and Table 4 on page 9. - Page 8 Wire Requirements for the CFK ・ Use twisted pair hookup wire of minimum diameter 24 AWG for all signal control lines, and 20 AWG for all power lines. ・ Strip no more than 5.5 mm of insulation from the end of the lead wires to minimize the possibility of short circuits.

Oscillation time varies with the inertial load, friction load, self-starting frequency and motor type. Be sure that the motor has come to a complete stop before inputting the All Windings Off Input signal. Activating the All Windings Off Input prior to the completion of motor oscillation may make the motor lose its resting position.
- Page 12 Resolution Selection Motor resolution can be set to 16 values by varying the connections to the Resolution Selection inputs D0 through D3. Therefore, the speed of the motor and the size of a step may be changed by modifying the microstep resolution, without changing the input pulse frequency. Do not change the resolution unless the pulse signal has stopped and the motor is stationary.

Page 13: Driver Output Current Control
6. Driver Output Current Control CFK54 □□ {Driver : DFC1507} CFK56 □□ {Driver : DFC1514} RUN and STOP currents are adjusted before shipment so that matched motor/driver units are ready for immediate use. However, the output current can be lowered to reduce heat generation and vibration. - Page 14 Adjusting the RUN Current Your driver is delivered with the RUN current set to the rated operating current. To change this value to reduce heat dissipation at high duty cycles, adjust the RUN potentiometer on the CFK driver to the appropriate current value setting shown in Figure 12. 1.
- Page 15 Adjusting the STOP Current The STOP current has been adjusted at the factory to 50% of the RUN current. To reduce the STOP current to lower the heat dissipation during standstill, use the following procedure. 1. Connect the motor to CN3 and insert an ammeter in the blue wire between terminal 1 and the motor, as shown in Figure 11 on page 13.
