Please take careful consideration of shaft overhung load and thrust load under all conditions. Please refer to the table below for permissible overhung load and thrust load of the shaft. ) Overhung load: A type of load to be applied in vertical directions on the shaft having effect on output shaft and bearings to shorten its life cycle. In case excessive overhung load is applied on the shaft, it may cause bearing damage, output shaft bending or fatigue failure caused by repeatedly applied excessive load. ) Thrust load: A type of load to be applied in parallel directions on the shaft having direct effect on output shaft and bearings to shorten its life cycle.

Overhung load Thrust load Refer to the table below for allowable shaft overhung load / thrust load. Permissible overhung load [kgf] by distance Motor Allowable from shaft tip (mm) type thrust load D= D=5 D= D=5 D= (7) 8.4 (8) (98) - 5 (49) () 6 5 (45) 7 (65) 3 (94) 34 (333) 39 (38) (98) (47) 54 (53) 6 (588) 68 (667) 79 (775) 3 (94) When installing the motor, make sure that excessive force is not applied to the motor cable. Also, the motor cable must not be pulled or inserted too tightly. If the motor is operated with excessive force applied on the cable, it may result in failed contact or disconnection. Please take safety measures when excessive force or continuous operation is required. Motor installation method When installing the motor, carefully consider heat radiation and vibration resistance. Mount the unit tightly on the surface of a metal with high thermal conductivity. (steel, aluminum, etc.) Use hexagon bolts, spring washers and flat washers when installing the motor. Please refer to the table below for mounting plate size and bolt types. Spring Washer Washer Hexagon wrench bolt Mounting plate Motor size Mounting plate size (depth) Bolt type 4 Min. 5mm M4 6 Min. 8mm M5 85 Min. mm M8 Load connection Use a flexible coupling when attaching a load (ball-screw, TM-screw, etc.) directly on the shaft of the motor. If the center does not match the load, vibration, degradation of the bearing, motor shaft damage, or other problems may occur. When attaching the load, do not modify or disassemble the motor or the shaft. When attaching the load of pulleys or belt please consider the thrust load, radial load, and shock. Ball screw or TM screw actuator type stepper motor Installation of motor With considering heat radiation and vibration isolation, make sure the motor's in-low to be kept as close as possible against a metal panel having high thermal conductivity such as iron or aluminum. Make sure to use mounting plates with thickness more than 8mm. As shown in the figure below, total 4 mounting TAP holes on F and F are used to fix rotary actuator. In case of using M4, screw tightening torque is N.m and 4.4N.m when using M5. Output FLANGE in-low part F (M5) F (M4) Flexible coupling Stepper Motor Body in-low part 3Do not apply excessive force on motor cable when installing rotary actuators. Do not forcibly pull or insert the cable. It may cause poor connection or disconnection of the cable. In case of frequent cable movement required application, proper safety countermeasures must be ensured. Installation of accessories (index table, arm, etc.) Mount the accessory (index table or arm) on output axis flange using M4 screw. Note that Ø3 in-low part is processed with C.3. It is necessary to process the accessory under C. to mount. Place a positioning pin on flange's positioning hole and push it in. Make sure not to place the pin on output flange. Do not use a hammer to mount the accessory (table or arm). It may cause product damage. Mount the accessory with hands in a gentle manner. 3 Make sure that accessory mounted on output axis to be fixed as tight as possible. It may cause an accident if an actuator is detached from the motor while driving. Proper use of product Observe the rated product specification. Do not apply rotational load on the motor while it stops. Do not apply excessive load on the motor while driving. It may cause motors to miss a step. 3 Use a sensor for home searching or division completed position detecting. & s Q-45

13 AK-G/AK-GB/AK-R/AK-RB Series Application example <Index table> <Moving arm> Do not disassemble or modify the product. It may cause a malfunction due to small dregs. Once disassembling the motor, its performance would significantly decline. Do not impact the motor. The air-gap, the distance between rotator and stator is processed as.5mm, but if it is impacted, the balance of air-gap can be broken and it may cause a malfunction. Installation examples <Index table> <Moving arm> bracket Detection pin Autonics photoelectric sensor BS5-LM Table bracket Detection pin Autonics photoelectric sensor BS5-TM Moving arm Install an additional sensor to detect home position and to ensure motor's positioning, number of rotation and its speed. Cautions During Use Installation condition : Install the motor in a place that meets certain conditions specified below. It may cause product damage if instructions are not following. It shall be used indoors. (This product is designed / manufactured to be installed on machinery as a part.) Within - to 5 (at non-freezing status) of ambient temperature Within 35 to 85%RH (at non-dew status) of ambient humidity The place without explosive, flammable and corrosive gas The place without direct ray of light The place without dust, dregs etc. The place without water, oil etc. The place where easy heat dissipation could be made The place where no continuous vibration or severe shock The place with less salt content The place with less electronic noise occurred by welding machine, motor etc. Use the motor within the rated torque range. The rated torque range indicates the maximum value of mechanical strength of gear part and the total of ac/ deceleration torque of start/stop and friction torque shall not be exceed the rated torque range, or, it may cause the breakdown of gear. Use the motor within the rated speed range. The rated speed range includes the revolution number of gear and pulse speed of motor. Use the motor within the rated speed range, or, it may shorten the life cycle of gear part. (Backlash is increased.) Be careful of backlash when positioning the motors in both CW/CCW directions. Backlash refers to the displacement occurred on motor's output shaft while gear's input axis is fixed. Geared type stepper motors are to realize high accuracy and low backlash. When positioning the motors in both CW/ CCW directions, however, backlash may possibly occur. Therefore, make sure that motor positioning will be made in one single direction in case of geared type motors. rise The surface temperature of motor shall be under and it can be significantly increased in case of running motor by constant current drive. In this case, use the fan to lower the temperature forcedly. Using at low temperature. Using motors at low temperature may cause reducing maximum starting / driving characteristics of the motor as ball bearing's grease consistency decreases due to low temperature. (Note that the lower the bearing's grease consistency, the higher the bearing's friction torques.) Start the motor in a steady manner since motor's torque is not to be influenced. Clack sound when using electromagnetic brake In case of brake built-in type motors, there occurs certain sound while turning on/off the power to the motor. This is not a product failure symptom. Do not strike or disassemble the product for this. Using electromagnetic brake Release brake force first by supplying the power to brake before starting the motor. If not, it may cause product malfunction and shortened life cycle of brake due to brake pad wear-out. Q-46
