Be sure to insert the correct connector surely. ※ Extension Power Cable and Extension Signal Cable are required to connect Gearmotor and Driver. ※ The cable that comes with the gearmotor extends 200mm. ※ Do not connect or disconnect wiring while the power is on. It may cause malfunction of the product. ※ When Q type (with brake type) is used, the power supply of 24VDC (10mA or more) is necessary aside from optional brake power supply device.

It is possible to add DC24V between B and B of the power cable. However, the varistor (82V and 1J or more) or the diode (100V and 1A or more) is necessary between B and B to protect the brake coil and contact point of the relay. - Page 6 2-2．Installation of Gearmotor （1） Proper location for installation （4） Tightening Torque Ambient Temperature： 0℃ to 40℃ fixing hole Tightening Torque Bolt Size Ambient Humidity： 85％ max. （mm） （N・m）｛（kgf・m）｝ Altitude： Sea level to 1,000m max. 2.9｛ 0.3｝ Environment： Well ventilated place free from 4.9｛ 0.5｝ corrosive gas, explosive gas vapor 13｛ 1.3｝ and/or dust. 13｛ 1.3｝ Installation Location： Indoors 25｛ 2.6｝ 44｛ 4.5｝ （2） Direction of Installation 69｛ 7.0｝ This product can be installed in any direction 108｛11 ｝ due to a grease lubrication system. 294｛30 ｝ （3） Method for Installation ① Attaching the mounting foot and flange Fix the product with the four bolts on a flat and machined surface free from vibration.

- Page 7 2 Attaching Chains, V-Belts, Gears, etc. ① In any connection, connect the units precisely, so that the center of the shaft of the reducer and that of the other equipment are parallel. ② The tension of the Chains/V-Belts and the coupling of the gear must be perpendicular to the center of the shaft. ③ Tension of the V-Belt: Excessive tensioning may result in damage to the bearings of the shaft. Tension of the Chain: Excessive tensioning may result in damage to the bearings of the shaft. If the chain is installed loosely, shock load will occur when the drive shaft starts rotation, and this can result in damage to the reducer and the other equipment. Therefore, adjust the tension of the chain properly. Proper Way of Use ・ Tensions for belt and chain are correct. ・ The positions of pulley and sprocket are also correct. Connecting machine Bad Example sprocket ・ The chain is too loose. ・ The sprocket is positioned in the reverse direction so that the load point moves Connecting to the shaft edge. machine 3 Attaching and Detaching a Driven Shaft to/from AF3S Type Hollow Shaft ●Attaching a Driven Shaft to the Reducer Hollow Shaft ① When attaching, be sure to smear extreme pressure agent (molybdenum disulfide, etc.) on the surface of driven shaft and the bore of the hollow shaft to avoid seizing, and insert the reducer to the driven shaft.

When the gap clearance becomes greater than the limit of gap to inhale, armature inhaling becomes difficult by magnet, making it impossible to release the brake. When using the motor continuously with this condition, the operation with brake-on causes overload and finally ALARM LED on the driver lights up, then the motor will stop. In order to operate this machine safely, it is recommended to check or adjust the brake gap periodically (Every 1 year or every 2 to 3 million cycles). ■Structure of brake 0.1kW, 0.2kW and 0.4kW ① ①Field ②Armature ⑧ ③Outer Disk ⑤ ④Spring 1 ⑦ ⑤Spring 2 ⑥Castellated Nut ④ ⑦Key ⑥ ⑧Hex Socket Head Cap bolt ② ⑨Brake Cover ③ ⑩Brake cover setting bolt ⑨ ⑩ ※ As a result of using brake for an extended period of time, naturally brake gap grew and finally brake releasing become impossible.
