1Presentation
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.
Serial mode of up to 32 devices connected in bus.
Movements in complete steps (8 micro steps), 1/2, 1/16, 1/32 or 1/64.
24-byte control frames (ASCII)
Execution of improved speed profiles.
Wide range of power supplies (24 -72 VDC).
Programmable phase current by means of PC software
Maximum current adjustment 8A phase in 40mA increments.
Setting of current standstill at 15, 40, 55 and 75% of the predefined maximum
current value.
Sinusoidal current control with harmonic suppression.
Input for End / Stop in switch mode or PNP with auxiliary power.
Opto-coupled auxiliary inputs.
Protections: temperature and voltage.
Plug connectors.
DIN rail mounting (optional).
MicroPaP products have a 1 year warranty against any
defects in manufacture. Furthermore, for the first 15 days,
MicroPaP guarantees the reimbursement of the purchase
price if the equipment is damaged or does not meet your
expectations.

2Initial 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.
Be sure to configure the motor characteristics before using the controller.
A USB-RS485 converter is required, microPaP can supply this as an option.
When the driver is starting up, wait until the green LED is turned on and the
red LED is permanently switched off so that the device is in working condition.
Before connecting the equipment to a RS-485 bus, all the
required parameters for its correct operation must be
configured in point-to-point mode. Remember 120 ohm
resistors on two bus end points!

3Connections
The SD-808 has plug-in terminals of different pitch (to minimize connection errors) for
communication signals, auxiliary input, limit switches and power connectors.

4Power 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. Increasing the voltage of the driver’s power supply
allows to increase the maximum speed of the motor without loss of steps.

5Motors
Motors with 4, 6 or 8 wires can be used. The 8-wire motors can be connected in series
or parallel allowing double the torque in the parallel connection.

Figure 4 6-wire connection
Placing outside this allowable power supply voltage rank for
the driver means that the driver protections will activate and
disconnect the power elements.
