  • Page 5: Presentation

    SD808 - USER MANUAL 1 Presentation Thank you for purchasing the new MICROPAP EASY MOTION SD-808 driver. SD-808 is a circuit designed for the operation of bipolar step motors with serial RS-485 communication. Main Features:  RS-485 asynchronous serial port galvanically isolated.

  • Page 6: Initial Precautions

    SD808 - USER MANUAL 2 Initial Precautions Make sure you read the information on motor current adjustment and motor connection method with special wiring configurations carefully.  Make sure that the power supply has enough power.  Choose wires with a suitable section, without pre-tinning or with pressed tips and as short as possible.

  • Page 10: Power Supply

    SD808 - USER MANUAL 4 Power Supply The voltage of the driver’s power supply must be between 24VDC and 72VDC, with a maximum current of 8A. The value of the right voltage to power a stepper motor depends on the desired high maximum speed performance.

    SD808 - USER MANUAL Figure 5 8-wire serial connection Figure 6 Parallel 8-wire connection  It is very important not to disconnect/connect the motor  with the controller supplied.  Check the connections before turning on the power!  5.1 Motor current The adjustment of the maximum current provided by the controller must be selected at the peak rated motor current (Inominal * 1.41) in order to avoid overheating in its windings which would shorten its life.

  • Page 12: Temperature Control

    SD808 - USER MANUAL 5.2 Temperature Control The driver self-protects against excessive current demands and associated temperature risings. The driver includes a heat sink designed to cool the parts of the circuit which, under normal operation, are subject to heating. For its proper ventilation, the driver must be maintained vertically.

  • Page 13: Operation Modes

    SD808 - USER MANUAL 6 Operation Modes The SD-808 driver allows you to work in two different modes: 6.1 Serial mode In this mode, the movements are made by sending a serial frame from a control device or PC. Serial communication can be point-to-point or through bus connection of several drivers.
