DVP-ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming

Application 2:

Speed control system and pressure control system work individually (use diagram of Example 2) Control purpose:

After the speed control operates in open loop for a period of time, adding pressure control system (PID instruction) to perform a close loop control.

Control properties:

Since the speed and pressure control systems are not interrelated, we have to structure an open loop for speed control first following by a close loop pressure control. If users afraid that the pressure control system changes excessively, consider adding the SC ramp-up function illustrated in Application 1 into this control. See the control diagram below.
