*2. Parameter is moved to Quick Programming Mode when PI controller is enabled.
Adjusting Analog Frequency Reference Using Parameters
The frequency reference can be input from the control circuit terminals using analog voltage or current signals
(analog input A2 only).
The input signal levels can be selected using
• H3-01 for the analog input A1
H3-08 for the analog input A2
•
Adjustments to the signals can be made using:
• H3-02 (Gain) and H3-03 (Bias) if analog input A1 is selected to be the frequency reference input
H3-10 (Gain) and H3-11 (Bias) if analog input A2 is selected to be the frequency reference input
•
Refer to Fig 6.23 for adjusting the signal using the gain and bias functions.
