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.

Part of the example program:

ADD D30 D31 D32

MOV D32 D1116

PID D1 D1110 D10 D5

MOV K1000 D40

DIV D32 K11 D32

MOV K255 D32
