2 Safety precautions 2 Safety precautions The precautions described below are intended to prevent danger or injury to the user and other personnel through safe, correct use of the product. Use the product only after carefully reading and fully understanding these instructions. Handling the product without observing the instructions that WARNING accompany a “Warning”symbol may result in serious injury or... - Page 5 2 Safety precautions Operation • Turn off the driver power in the event of a power failure, or the motor will suddenly start when the power is restored and may cause injury or damage to equipment. • Do not use it in a vertical applications. When the driver protection function is triggered, the motor will stop operating.
- Page 6 2 Safety precautions • Before moving the motor directly with the hands (as in the case of manual positioning), confirm that the driver operation input is “OFF” to prevent injury. • Do not perform the motor’s starting and stopping operations by turning the power on and off.
- Page 7 2 Safety precautions Noise measures The electrical noise is of two types: One is a noise to invade into the driver from the outside and cause the driver malfunction, and the other is a noise to emit from the driver and cause peripheral equipments malfunction. For the noise that is invaded from the outside, take measures to prevent the driver malfunction.

Page 13: Load Installation
4 Installation 4.3 Load installation When installing the load to the motor or gearhead, ensure that the motor output shaft or gearhead output shaft and load shaft are aligned with each other. Optional flexible couplings are available (sold separately). The output shaft of the round shaft type and geared type is provided with a flat. Use double point screws on the flat and provide reliable locking to prevent idle rotation of the load. -
Page 14: Driver Installation
4 Installation 4.4 Driver installation Direction of installation The driver is designed on the basis of heat radiation by air convection and heat conduction to the housing. When installing the driver in the housing, use four installation holes on the driver and install it in the vertical or horizontal direction. -
Page 15: Installing And Wiring In Compliance With Emc Directive
EN 61000-6-2 Installing and wiring Effective measures must be taken against the EMI that the AXH series may give to adjacent control-system equipment, as well as the EMS of the AXH series itself, in order to prevent a serious functional impediment in the machinery. - Page 16 4 Installation • Ferrite core • When suppressing effect by noise propagation, use a ferrite core. • Use the ferrite core for extending the motor cable Use ferrite core 7427122 by Wurth Electronik GmbH & Co. KG, ZCAT3035-1330 by TDK Corporation or its equivalent. Connect the ferrite cores as close as possible to the driver.
- Page 17 4 Installation • Others • Connect the motor, driver and other peripheral control equipment directly to the grounding point so as to prevent a potential difference from developing between grounds. • When relays or electromagnetic switches are used together with the system, use noise filters and CR circuits to suppress surges generated by them.

Page 27: Setting The Running Speed
6 Setting the running speed 6 Setting the running speed In addition to the driver internal potentiometer, the external potentiometer or external DC voltage can be used to set the motor running speed. The motor speed range is from 100 to 3000 r/min for the case of the motor alone. Two running speeds can be set by combining the internal potentiometer and external potentiometer, or the internal potentiometer and external DC voltage. - Page 28 6 Setting the running speed • To set the running speed only by the external potentiometer, there is no problem if the INT.VR/EXT input is not connected. • To perform operation by switching the motor running speed, use the INT.VR/EXT to switch the external potentiometer and internal potentiometer. To use a shielded cable for connection with the external potentiometer, Note connection should be made close to the input/output signal cable connector.
