Page 164: Appendix: Process Pid Control
Appendix: Process PID control What this chapter contains The chapter contains instructions on quick configuration of the process control, gives an application example and describes the PID sleep functionality. Process PID control There is a built-in PID controller in the drive. The controller can be used to control process variables such as pressure, flow or fluid level.Page 165: Pressure Boost Pump
4017 ACT2 INPUT: If a second feedback is used, configure also this actual value (4020 ACT2 MINIMUM and 4021 ACT2 MAXIMUM). 4001 GAIN, 4002 INTEGRATION TIME, 4003 DERIVATION TIME, 4005 ERROR VALUE INV: Configure the desired gain, integration time, derivation time and error value inversion when needed.Page 166: How To Scale The Pid Actual (Feedback) Signal 0...10 Bar / 4...20 Ma
How to scale the PID actual (feedback) signal 0…10 bar / 4…20 mA PID feedback is connected to AI1 and 4016 ACT1 INPUT is set to AI1. 1. Set 9902 APPLICATION MACRO to 6 (PID CONTROL). Check scaling: 1301 MINIMUM AI1 as default 20% and 1302 MAXIMUM AI1 as default 100%. Check that 1106 REF2 SELECT is set to 19 (PID1OUT).Page 167: Pid Sleep Functionality
PID sleep functionality The block diagram below illustrates the sleep function enable/disable logic. The sleep function can be put into use only when the PID control is active. Compare Select output NOT SEL frequency INTERNAL 1<2 Delay 4023 Set/Reset 4022 &...- Page 168 Sleep function for a PID controlled pressure boost pump (when parameter 4022 SLEEP SELECTION is set to 7 = INTERNAL): The water consumption falls at night. As a consequence, the PID process controller decreases the motor speed. However, due to natural losses in the pipes and the low efficiency of the centrifugal pump at low speeds, the motor does not stop but keeps rotating.
