EWM-P-AA - Digital card for pressure and force control in closed loop systems


This card is designed for pressure controlled servo pumps. It manages closed loop control of pressure reducing and pressure relief valves.

The card works as a bypass control module. The command value is directly transferred to the control output (pressure valve) and the closed loop compensates only the linearity failures. In most of cases the optimization is possible without any measuring instruments (a pressure sensor is necessary only).

It has an integral power amplifier for direct control of proportional valves.

Card setup via software only, through an on-board USB-B port. Customizable parameters are: ramp up, ramp down, PID parameters, dither, frequency and amplitude, PWM, maximum and minimum pressure.
