1 RUN LOW HIGH POWER ALARM STAND-BY Brushless DC Systems AXU Series The AXU Series combines a compact, brushless DC motor with a speed control unit. These systems provide space savings, easy wiring and simple operation. The gearhead shown in the photograph is sold separately. Features Easy Connection and Simple Operation Just connect the motor connector to the control unit, and the AXU is ready for immediate use. The rate of rotation is easy to adjust using the speed control dial on the front of the speed control unit. External Control Possible RunStop, rotation direction and instantaneous stops can be controlled with external signals. External Control Signal RunStop Change Direction Instantaneous Stop SPEED CONTROL UNIT AXUD25A ORIENTAL MOTOR Thin and Compact Compared to an AC speed control motor, the use of a brushless DC motor significantly reduces the size of the motor. Length: 1.65 inch (42 mm) for 1 W, 25 W 2.24 inch (57 mm) for 4 W, 9 W Wide Speed Range and Constant Torque Even with an available speed range of 12 rmin, the AXU Series motor maintains a constant torque. Safety Standards and CE Marking Standards UL195 CSA C22.2 No.95 EN695 EN64-1 EN64-5 UL58C CSA C22.2 No.14 EN695 EN5178 Certification Body UL Standards File No. E282 Conform to ENIEC Standards UL E Conform to ENIEC Standards Superior Speed Stability Speed regulation characteristics are 2% maximum with load, 1% maximum with voltage and 1% maximum with temperature. AccelerationDeceleration Functions AXU Series motors can be set to accelerate and decelerate when the start and stop input is used. Protective Functions The AXU Series is equipped with protective functions to handle overload, overvoltage, out-of-phase, undervoltage and overspeed. When an abnormality is detected, an alarm is output and the motor comes to a stop. Construction IP65 A grade IP65 indicates protection against jets of water. It is safety if get splashed accidentally. However it is not suitable for washing the motor nor being operated under the circumstance of being splashed constantly. CE Marking Low Voltage Directives EMC Directives When the system is approved under various safety standards, the model names on the motor and control unit nameplates are the approved model names. List of and Combinations Page B-57 Details of Safety Standards Page G-2 The EMC value changes according to the wiring and layout. Therefore, the final EMC level must be checked with the motorcontrol unit incorporated in the equipment. B-46 Features B-46 System Configuration B-47 Specifications B-48 Characteristics B-5

MOTOR NC L N SPEED CONTROL UNIT AXUD25A POWER RUN LOW HIGH STAND-BY ALARM Front of Connection Diagrams and Connection Ground For the Protective Earth cable, use a cable with a diameter equivalent to AWG18 or more. Operation The direction of motor rotation is as viewed from the output shaft end of the motor. "" indicates clockwise direction, while "" indicates counterclockwise direction. Operation Using the RUNSTAND-BY Switch When the RUNSTAND-BY switch is set to the "RUN" position, the motor will run. When it is set to the "STAND-BY" position, the motor will stop. The direction of rotation depends on how the short circuit bar at the back of control unit is connected. Connect the short circuit bar between the and or and. Do not use the short circuit bar for any other purpose. Rotation Rotation Short Circuit Bar Short Circuit Bar Operating Using External Signals Set the RUNSTAND-BY switch to the "RUN" position.

Introduction BX FBL2 AXU AXH BHF ES US Brushless DC Systems AC Input DC Input AC Systems Terminal cover Input output connection signal terminals For connection, use a twisted pair or shielded wire Terminal cover Connection Insert the motor cable connector into the motor connector (MOTOR) on the control unit. Insert it until a click sound is audible. To expand the distance between the motor and control unit, use an optional extension cable. The connection can be extended to a maximum of 4.4 feet (1.5 m). Extension cable Page B-57 Power Connection Connect the included power supply cable to the power supply terminal of the control unit. When the included power supply cable is not used, use a cable with a diameter equivalent to AWG22 or more. In that case, round crimp terminals with insulation should be used.

Small-capacity switch and relay Use a small-capacity contact type relay capable of opening and closing 12 VDC, 5 ma. Transistor output type controller Rotation Direction of (clockwise) directional operation When input is turned on, the motor runs in a clockwise direction. When input is turned off, the motor stops. (counterclockwise) directional operation When input is turned on, the motor runs in a counterclockwise direction. When input is turned off, the motor stops. When both the and inputs are turned on simultaneously, the motor stops instantly. Instantaneous reversing operation is not possible. Notes: Wait for more than 2 ms when changing input signals of and. Do not use a solid state relay (SSR) to turn on or off power. The motor and control unit may be damaged if it is used. When you want to use the controller with a built-in clamp diode, pay attention to the sequence of turning on or off the power. Power ON : Controller ON ON Power OFF : OFF Controller OFF External Controller Vcc OFF OFF ON ON +14V If the control unit power is turned on first when connected as shown above, or the controller power is turned off with the control unit power turned on, current will be applied, as indicated by the arrows in the diagram. This may cause the motor to run. When the power is turned on or off simultaneously, the motor may run temporarily due to differences in power capacity. The controller power must be turned on first, and control unit power must be turned off first. Output Circuit Connection Example Notes: The signal output is Open Collector Output. Use the power supply of 26.4 VDC or less to connect the limit resistance (R) so that output current does not exceed 1 ma. SPEED Output The speed output signal is synchronized with the motor speed. The system outputs pulses (with a width of approximately.5 ms) at a rate of pulses per rotation of the motor output shaft. You can measure the speed output frequency and calculate motor speed. Speed (rmin) SPEED Output Frequency [Hz] 1 6 SPEED Output Frequency (Hz) T.5ms T External Controller R Vcc SPEED OUT ALARM OUT To check the reduced motor speed visually (the speed at the motor output shaft or at the gearhead output shaft), connect a speed indicator SDM496 (sold separately). Speed Indicator Page A-214 Notes for Connection: When you want to extend the inputoutput signal cable, the length must not exceed 6.6ft. (2m). The cable should be as short as possible in order to minimize noise. Signal wires and motor wires should be kept away from equipment, power cables and other sources of magnetic noise. Setting the AccelerationDeceleration Time The motor accelerates slowly when it starts up and decelerates slowly when it stops. This acceleration deceleration time can be set within the range from.5 to 1 sec (2 rmin without load). The time can be set using the accelerationdeceleration potentiometer. Remove the front panel of control unit to access the potentiometer. The figure shows the control unit with the front panel removed.
