  • Page 12: Installation

    Installation Installation This section covers the driver's installation location and method. Location for installation The driver is designed and manufactured for use as a built-in component in industrial equipment. Install it in a well-ventilated place satisfying the following conditions, where the product can be easily accessed for the purpose of inspection.
  • Page 13 Conductive Noise Immunity Test IEC 61000-4-6  Power supply The DRL series products are specifi cally designed for DC power supply input. Use a DC power supply (such as a switching power supply) compliant with the EMC directive.  Mains fi lter Connect a mains fi lter on the input side of the DC power supply so as to prevent the noise generated in the driver from being transmitted externally via the power supply line.
  • Page 14 Installation  Wiring the power supply cable and I/O cable Use a shielded cable of AWG22 (0.3 mm ) or more in diameter for the driver power supply cable. Use a shielded cable of AWG24 (0.2 mm ) or more in diameter for the driver I/O cable, and keep it as short as possible. When grounding a shielded cable, use a metal cable clamp that contacts Shielded cable the shielded cable over the entire perimeter.

  • Page 23: Setting

    Setting Setting This section covers the methods of setting the resolution, switching pulse input modes, switching , smooth drive function and adjusting the motor current. Resolution When setting the actuator's resolution, use the resolution setting switches (DATA1, DATA2) and the resolution select switches (R1, R2).
  • Page 24 Setting  DRL42 With high-resolution motors, the resolution becomes one-half the applicable value shown in the table below. Resolution Resolution Number of Number of setting switches Resolution 1 [mm (in.)] setting switches Resolution 2 [mm (in.)] divisions 1 divisions 2 DATA1/DATA2 DATA1/DATA2 0.004 (0.00016)
  • Page 25 Setting  The resolutions are given as theoretical values.  The resolution is calculated by dividing the basic resolution by the division number.  The C/S (resolution switching) input is eff ective only with respect to the division number selected for resolution 1 or resolution 2.
  • Page 26 Setting Motor currents  Motor operating current Factory setting: Motor's rated current  Motor standstill current Factory setting: 50% of motor operating current When the load is light and there is a margin for thrust, the motor's operating vibration and the temperature increase of the motor and driver can be held down by lowering the motor's operating current and standstill current.

  • Page 30  Positioning time The following explains the formula for calculating the positioning time (reference value) of the DRL series: Since there is settling time dependent on such factors as the load's inertial moment and the speed setting, use these values only as a reference.
  • Page 31  Settling time With the DRL series, the load inertial moment and other factors cause a response delay with respect to the pulse input. A delay thus caused at stopping is called the "settling time". The calculation of accurate positioning time requires that this settling time be considered.
