    1 Introduction 1 Introduction Before use Only qualified personnel should work with the product. Use the product correctly after thoroughly reading the section “Safety precautions”. The product described in this manual has been designed and manufactured for use in general industrial machinery, and must not be used for any other purpose. Oriental Motor Co., Ltd.
  • Page 3 1 Introduction System configuration Operating the CSK series requires a controller equipped with a pulse output function. Controller Driver Motor Digital I/O DC power input As for the voltage supply to the driver, use an EMC-compliant DC power supply with reinforced insulation on both the primary and secondary sides. Compliance with the EC Directives If compliance with the European Low Voltage Directive and EMC Directive is required, the user is advised to take full responsibility for the following measures:...

  • Page 8: Precautions For Use

    3 Precautions for use 3 Precautions for use This section covers limitations and requirements the user should consider when using the CSK series. • Do not apply an overhung load and thrust load in excess of the specified permissible limit. Be sure to operate the motor within the specified permissible limit of overhung load and thrust load.
  • Page 9 3 Precautions for use • Maximum static torque at excitation The maximum static torque at excitation represents the torque when the motor is excited at the rated current. If the motor is combined with a dedicated driver, the automatic current cutback function reduces the maximum static torque at excitation to around 40%.
