CL-00 Feedback 1 Source
Option: Function:
Up to three different feedback signals can be used to provide the feedback signal for the frequency
converter’s PID Controller.
This parameter defines which input will be used as the source of the first feedback signal.
Analog input X30/11 and Analog input X30/12 refer to inputs on the optional General Purpose I/O board.
(OPCGPIO).
Analog Input X42/1, X42/3, X42/5 refer to inputs on the optional Analog I/O board (OPCAIO).

NB!
If a feedback is not used, its source must be set to No Function [0]. par. CL-20 Feedback Function determines how the three possible feedbacks will be used by
the PID Controller.
CL-01 Feedback 1 Conversion
Option: Function:
This parameter allows a conversion function to be applied to Feedback 1.
[0] * Linear Linear [0] has no effect on the feedback.
[1] Square root Square root [1] is commonly used when a pressure sensor is used to provide flow feedback
(
( flow ∝ pressure ) ).
[2] Pressure to temperature Pressure to temperature [2] is used in compressor applications to provide temperature feedback using a
pressure sensor. The temperature of the refrigerant is calculated using the following formula:
Temperature =
A 2
(
ln
(
Pe +1
)
− A 1
)
−
A 3
, where A1, A2 and A3 are refrigerant-specific constants.
The refrigerant must be selected in par. CL-30 Refrigerant. par. CL-21 Setpoint 1 through par.
CL-23 Setpoint 3 allow the values of A1, A2 and A3 to be entered for a refrigerant that is not listed in par.
CL-30 Refrigerant.
