(T) Multi-Function Input Terminal Parameters
Parameters
5 - 404
Analog input bias/gain calibration (C2 (Pr. 902) to C7 (Pr. 905), C12 (Pr. 917) to C15 (Pr. 918))
●
The "bias" and "gain" functions serve to adjust the relationship between a setting input signal and
the output frequency. A setting input signal is such as 0 to 5 V DC/0 to 10 V or 4 to 20 mA DC
externally input to set the output frequency.
●
Set the terminal 2 input bias frequency by using C2 (Pr. 902).
(It is initially set to the frequency at 0 V.)
●
Set the output frequency to the frequency command voltage (current) set by the Pr. 73 "Analog
input selection" by using Pr. 125.
●
Set the bias frequency of the terminal 1 input using C12 (Pr. 917).
(It is initially set to the frequency at 0 V.)
●
Set the gain frequency of the terminal 1 input using C14 (Pr. 918).
(It is initially set to the frequency at 10 V.)
●
Set the bias frequency of the terminal 4 input using C5 (Pr. 904).
(It is initially set to the frequency at 4 mA.)
●
Set the output frequency for 20 mA of the frequency command current (4 to 20 mA) by using Pr. 26.
