  • Page 5 Schematic and Interface Definition 4) mailing address Users can control up to 30 DS-OLS7-FRS4 drives simultaneously using the RS-485 bus. The drive communication address setting uses a 5-digit DIP switch. The address setting range is 1-32, where address 32 is reserved for the system. When the drive address setting is greater than 31, it needs to be set and saved using the upper debugging software.

Turn the SW8 switch to ON when the power is off. Then, after power-on, without pulse input, the SW8 gear dial switch is turned from the ON position to the OFF position.
  • Page 7 Schematic and Interface Definition 8) Idle current After 500 milliseconds of no pulse input, the current will automatically enter the idle current to reduce motor heating. The current is restored to the set value during pulse input. 9) Indicator function This product has 2 LEDs indicating that the light shows the working status: 1.
  • Page 8 Power Supply 4. Power Supply 4.1 Voltage The chopper driver continuously changes the size and direction of the motor winding voltage and detects the current to obtain accurate phase current. If both high efficiency and low noise are to be ensured, the driver supply voltage shall be at least 5 times the motor rated phase voltage (that is, the motor rated phase current ×...
  • Page 9 Power Supply / Motor Connection regenerative discharge device. Please note that the positive and negative terminals of the power supply should not be inversely connected when there is no anti-inversely connected function. The driver damage caused by inversely connected power supply cannot be guaranteed. 5.
  • Page 10 Motor Connection / Signal Input 1) The corresponding colors of different motors are different. When using the motors, the specifications of the motors shall prevail. For example, the colors of 57 and 86 motor wires are different. 2) The phases are relative, but the windings of different phases cannot be connected to the terminals of the same phase of the driver (A +, A- is one phase, B +, B- is the other phase).

  • Page 13 Typical Connection of Signal Output 8. Typical Connection of Signal Output 8.1 Relay Connection When the relay is connected, it is required to connect diodes at both ends of the Notes relay (such as IN4000 series) 8.2 Optocoupler Connection The alarm output is optically isolated, with a maximum voltage of 30VDC and a maximum saturation current of 50mA.
  • Page 14 Typical Connection of Signal Output / Wiring Requirements example Connecting with Keyence products 9. Wiring Requirements 1) In order to prevent the driver from being disturbed, it is recommended to use shielded cable for the control signal, and the shield layer should be shorted to the ground. Except for special requirements, the shielded wire of the control signal cable is grounded at one end: the upper end of the shielded cable is grounded The driver end of the wire is left floating.

The power device of the driver will generate heat. If it works continuously under high input voltage and high power conditions, it should expand the effective heat dissipation area or force cooling.
