  • Page 13: Function

    Series 651 DESIGN AND FUNCTION Function The valve plate acts, due to its pendulum motion, as a throttling element and varies the conductance of the valve opening. The integrated controller calculates the required plate position to achieve the set point pressure. Actuation is performed by a stepper motor. An encoder monitors the position. This principle ensures fast and accurate process pressure control.

  • Page 15: Principle Of A Pressure Control System

    Series 651 DESIGN AND FUNCTION 3.2.1.1 Way of operation The controller compares the actual pressure in the process chamber given by the pressure sensor with the preset pressure. The controller uses the difference between actual and set pressure to calculate the correct position of the control valve. The controller drives the control valve into the correct position and the actual pressure again equals the set pressure.

  • Page 53 Series 651 INSTALLATION 4.6.1.2 Sensor delay adjustment Sensor delay adjustment effects: Stability Default value is 0sensorDeay0. Adjustment range is from 0 to 1.0s. Pipes and orifices for sensor attachment delay response time and so badly impact pressure control stability. By adapting this parameter to the approximate delay time stability problems can be reduced. But control response time will be slowed down by this measure.
  • Page 54 INSTALLATION Series 651 4.6.1.3 Setpoint ramp adjustment Setpoint ramp effects: Undershoot of pressure, Response time Default value for Setpoint Ramp is 0. Adjustment range for Setpoint Ramp is from 0 to 10 s. This parameter defines the time that is used to decrease / raise pressure between 2 setpoints. Especially in pressure decrease situations at low flows pressure response can be improved much by adapting setpoint ramp time.
  • Page 55 Series 651 INSTALLATION 4.6.1.4 Valve speed adjustment Valve speed effects: Response time Default value is 1000. Adjustment range is from 1 to 1000. This parameter effects valve plate actuating speed. Speed adjustment is effective for PRESSURE CONTROL and POSITION CONTROL. Normally best pressure control response is achieved with max.

    INSTALLATION Series 651 4.6.2 Tuning of pressure control performance with fixed PI control 4.6.2.1 Optimizing P gain and I gain This valve may be used for downstream or upstream pressure control depending on configuration. The PI parameters of the pressure controller require correct adjustment. These parameters must be set once during system setup and are stored in the device memory which is power fail save.
  • Page 57 Series 651 INSTALLATION Optimizing P gain While optimizing P gain, the gas flow determined above has to be constant all the time. Start optimization with P gain set to 1.0 and I gain set to 0.0. Set chamber pressure to SP2, wait until the pressure is stable. Set pressure to SP1. If the transition from SP2 to SP1 results in a significant pressure over shoot or even does not stabilize at all, the P gain is too high.
