Chức năng Multi-Speed lệnh Bước 1 Bước lệnh tốc độ Multi-2 Multi-Speed lệnh Bước 3 lệnh tốc độ Multi-Bước Mô tả Bốn yếu tố đầu vào lựa chọn tốc độ đa định nghĩa bởi Pr.05.00 Pr.05.14 như thể hiện trong biểu đồ ở cuối của bảng này. | Chapter 4 Parameters RS485 BUS PC command Handling time of AC drive Max. 6msec Response Delay Time Pr.09.07 Response Message of AC Drive 4-98 Revision June 2007 0ELE V1.00 Chapter 4 Parameters Group 10 PID Control 10.00 PID Set Point Selection Factory Setting 0 Settings 0 Disable 1 Digital keypad UP DOWN keys 2 AVI 0 10VDC 3 ACI 4 20mA 4 PID set point Pr.10.11 10.01 Input Terminal for PID Feedback Factory Setting 0 Settings 0 Positive PID feedback from external terminal AVI 0 10VDC 1 Negative PID feedback from external terminal AVI 0 10VDC 2 Positive PID feedback from external terminal ACI 4 20mA 3 Negative PID feedback from external terminal ACI 4 20mA ffl Note that the measured variable feedback controls the output frequency Hz . Select input terminal accordingly. Make sure this parameter setting does not conflict with the setting for Pr.10.00 Master Frequency . ffl When Pr.10.00 is set to 2 or 3 the set point Master Frequency for PID control is obtained from the AVI or ACI external terminal 0 to 10V or 4-20mA or from multi-step speed. When Pr.10.00 is set to 1 the set point is obtained from the keypad. Negative feedback means target value - feedback Positive feedback means -target value feedback. 10.11 XSource of PID Set point Unit 0.01 Settings 0.00 to 600.0Hz Factory Setting 0.00 ffl This parameter is used in conjunction with Pr.10.00 set 4 to input a set point in Hz. 10.02 XProportional Gain P Unit 0. 1 Settings 0.0 to 10.0 Factory Setting 1.0 ffl This parameter specifies proportional control and associated gain P . If the other two gains I and D are set to zero proportional control is the only one effective. With 10 deviation error and P 1 the output will be P x10 x Master Frequency. Revision June 2007 0ELE V1.00 4-99 Chapter 4 Parameters NOTE The parameter can be set during operation for easy tuning. 10.03 XIntegral Time I Unit 0.01 Settings 0.00 to 100.0 sec Factory Setting 1.00 0.00 Disable ffl This parameter specifies integral control continual sum of .
