Product Overall Description
SS808H is ECON technology’s latest SS series hybrid servo drives with LCD display, its power input is 24-80 VDC,and the output current is 0.5 -6A(peak). It can match Nema17,23,24 and 34 hybrid servo motors (stepper motor with encoder) with the position loop closed in real time.
Based on latest DSP technology and ECON technology’s advanced control algorithm, SS808H hybrid servo drive applies servo vector control for hybrid servo motor. it combines features of both open loop steppers and brushless servo systems, and offers many unique advanced features for excellent motion control system performance.
When an SS808H hybrid servo drive is implemented with a ECON technology’s EC series hybrid servo motor, there is No Configuration Needed for almost all applications. The default resolution is 2,000 pulses ,and the user can also easily change the output resolution to resolutions 400 to 51,200 via DIP switches. With ECON technology’s Protuner, user can also set custom settings of resolution, current & position loop parameters, idle current percentage, etc.

There are two ways to set the hybrid servo driver parameters,one is by ProTuner software;another one is use DIP switch to set.
About the ProTuner software,the LCD display easy servo driver has a USB (RS232-TTL-3.3V)communication port.This port can be used for tuning the parameters of drive(current, filter time,pulse type,open/closed loop mode,etc),it is connected to USB device(a special device is offered by ECON tech ) or protuner of PC by USB-RS232 cable.
As to the DIP switch,there are SW1 to SW8,SW1~SW4 set the Pulse/Revolution,SW5 and SW6 set the direction and function mode,SW7 and SW8 set the motor type. For detail information,can check SS808H user manual.

1.3 Wiring Notes
--In order to improve anti-interference performance of the drive, it is recommended to use twisted pair shield cable.
--To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires should not be tied up together. It is better to separate them by at least 10 cm, otherwise the disturbing signals generated by motor will easily disturb pulse direction signals, causing motor position error, system instability and other failures.
-- If a power supply serves several drives, separately connecting the drives is recommended instead of daisy-chaining.
--It is prohibited to pull and plug power connector while the drive is powered ON, because there is high current flowing through motor coils (even when motor is at standstill). Pulling or plugging power connector with power on will cause extremely high back-EMF voltage surge, which may damage the drive.
