Operation Method There is a difference in operation method between the US26, US31, US42, US4 types and the US6, US9 types. Rotation Connect the motor lead wire connectors to the control unit. Then connect the power cable [2 m (6.6 ft.), AWG18] to the AC power supply. When the RUN/STAND-BY switch on the control unit is set to RUN, the motor rotates in the clockwise (CW) direction as viewed from the motor output shaft. Control units are set for clockwise rotation at shipment. The rotation direction on the gearhead output shaft may be the opposite direction of the motor shaft depending on the gear ratio. Changing Speed When dial on the speed potentiometer located on the control unit is turned in a clockwise direction, motor speed increases; when turned in the counterclockwise direction, motor speed decreases. Motor speed can be set and adjusted over a range of 9 to 14 r/min at Hz, 9 to 16 r/min at 6 Hz. Stopping When the RUN/STAND-BY switch on the control unit is set to STAND-BY, the motor stops. This switch is not a power ON/OFF switch. If the motor is to be stopped for a long time, a separate power ON/OFF switch should be installed. Switching the Rotation Direction US26, US31, US42 and US4 Types (Capacitor is included in the control unit.) Uni-Directional Rotation: When the rotation direction of motor needs to be reversed, change the terminal used for attaching the power cable, located at the rear panel of control unit, from terminal N (CW) to terminal N (CCW). The power cable connections are located at terminals L and N (CW) at shipment. This should always be done with the power OFF. Bi-Directional Rotation: Install an additional power switch (SW1) and CW/CCW switch (SW2) as shown on page 17, and use these switches to change the rotation direction. Motor cannot be reversed instantaneously. Turn SW1 off and wait until the motor has come to a complete stop before switching SW2. US6 and US9 Types (Connection of the included capacitor is necessary.) Uni-Directional Rotation: When the rotation direction of motor needs to be reversed, change the terminal used for attaching the power cable, located at the rear panel of control unit, from terminals N (CW) and N (COM) to terminals N (COM) and N (CCW). The power cable connections are located at terminals N (CW) and N (COM) at shipment. This should always be done with the power OFF. Bi-Directional Rotation: Install an additional power switch (SW1) and CW/CCW switch (SW2) as shown on page 17, and use these switches to change the rotation direction. Motor cannot be reversed instantaneously. Turn SW1 off and wait until the motor has come to a complete stop before switching SW2.

Excessive impact loads can cause the gearhead or motor damage. The table below gives values for permissible load inertia on the motor shaft. Use the motor and gearhead within these parameters. The permissible load inertia (J) on the gearhead output shaft is calculated with the following formulas. The life of the gearhead when operating at the permissible load inertia with instantaneous stops of the speed control motors is approximately two million cycles.
