1 RoHS-Compliant Speed Control Motor and Control Unit Package US Series Single-Phase 11/11 VAC Single-Phase 22/23 VAC

2 RoHS-Compliant Speed Control Motor and Control Unit Package US Series Single-Phase 11/11 VAC, Single-Phase 22/23 VAC The US Series is a panel mounted control unit and speed control motor package, which conforms to the RoHS Directive. Wiring is performed by connecting with easy-to-use connectors. This series is optimal for easy speed control applications. Instantaneous stop function is not available. Features Easy Connection The operation is possible just by connecting the control unit into the power supply after connecting the motor and control unit through easy-to-use connectors. Easy Operation The speed can be set easily with the potentiometer on the front panel of the control unit. Approved by Major Safety Standards The US Series is recognized by UL and CSA, and certified under the China Compulsory Certification System (CCC System). CE Marking is used in accordance with the Low Voltage Directive and EMC Directive. Safety Standards and CE Marking Motor Control Unit Gearhead shown in the photograph is sold separately. Long Life, Low Noise GN-S Gearhead is Available. [Applicable motors: 6 W (1/12 HP) to 4 W (1/19 HP)] The new "long life, low noise GN-S gearhead" achieves a long rated life of 1 hours, twice the level of a conventional gearhead, by adopting innovative technologies and structure. Also, the gearhead is low noise designed. Protective Earth Terminal on Motor [6 W (1/12 HP) to 4 W (1/19 HP)] RoHS-Compliant The US Series conforms to the RoHS Directive that prohibits the use of six chemical substances including lead and cadmium. RoHS (Restriction of Hazardous Substances) Directive: Directive on restriction of the use of certain hazardous substances in electrical and electronic equipment (22/9/EC). The RoHS Directive prohibits the use of six chemical substances in electrical and electronic products sold in the EU member states. The six controlled substances are: lead, hexavalent chromium, cadmium, mercury and two specific brominated flameretardants (PBB and PBDE).

7 Gearmotor Torque Table Gearheads and decimal gearheads are sold separately. Enter the gear ratio in the box ( ) within the model name. A colored background ( ) indicates gear shaft rotation in the same direction as the motor shaft, while the others rotate in the opposite direction. To reduce the speed beyond the gear ratio in the table, attach a decimal gearhead of gear ratio 1:1 between the gearhead and the motor. In that case, the permissible torques are as follows. 2GN SA: 3 N m (26 lb-in), 3GN SA: N m (44 lb-in) 4GN SA: 8 N m (7 lb-in) [6 N m (3 lb-in) when a gearhead of 2:1 to 36:1 is attached] GN SA: 1 N m (88 lb-in), GU KA: 2 N m (177 lb-in) Single-Phase 11/11 VAC Model Gear Ratio Unit = N m (lb-in) Motor/ Gearhead US26-41U2 /2GN SA US31-41U2 /3GN SA US42-41U2 /4GN SA US4-41U2 /GN SA US6-1U2 /GU KA US9-1U2 /GU KA Motor Speed r/min (1.6).9 (.79).3 (2.6).11 (.97).49 (4.3).12 (1.6).63 (.).17 (1.) 1.2 (1.6).49 (4.3) 1.8 (1.9).49 (4.3).1 (1.32).11 (.97).36 (3.1).13 (1.1).8 (.1).1 (1.32).76 (6.7).2 (1.77) 1.4 (12.3).8 (.1) 2.1 (18.).8 (.1).2 (1.77).1 (1.32).1 (4.).18 (1.9).81 (7.1).2 (1.77) 1.1 (9.7).28 (2.4) 2.

18 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.

Once the motor or gearhead are determined, the coupling can be selected. Features Couplings come with shaft holes and have standardized combinations for different diameter shaft holes. Characteristics are the same for clockwise and counterclockwise rotation. Oil-resistant and electrically insulated Aluminum alloy construction The driven shaft is not damaged, since shafts are joined by clamping. Easy installation due to a separated hub and sleeve design Refer to page A-28 of the General Catalog 26/27 for details of the products. 2GN SA Gearhead Model 3GN SA 4GN SA 4GN RAA GN SA GN RAA GU KA GU RAA Coupling Type MCL2 MCL3 MCL3 MCL3 MCL4 MCL3 MCL4 MCL4 MCL Enter the gear ratio in the box ( ) within the model name.
