1) 0-5V control signal
2) revolutions according to the voltage 3000- 9000 RPM for the pump without load
3) the maximum pressure of 10.5bar results from the maximum current limited to 17A 
4) limiting the internal temperature to 120 degrees. the controller requires VERY GOOD cooling, especially if it is to work with high pressures / currents otherwise after exceeding 120 degrees will automatically shut down.


Additional inforamtion about the driver:
• 3 phase wires
- U- black
- V- yellow
- W- red 
• 2 power cables
- 12V -red 
- GND- black
• one wire (blue) of the external speed controller 0-5V voltage signal
- 0V - 3000 RPM (no load) 
- 5V - 9000 RPM (no load) 
• 2 - CAN wires, communication interface for cooperation with software.
