9.2.12 Analog input Voltage, electric current Transition [AT : Analog Signal Transition]
This inverter has three kinds of external analog input terminals.
z O-L : Direct-current voltage 0~10V Approval
z OI-L : Direct current 4~20mA Approval
z 02-L : Direct-current voltage -10V ~ +10V Approval
According to the combination AT terminal value(I049) and O2 value(I038), 15 kinds of analog input
are selectable.
(1) Analog external signal selection by AT terminal selection:
① AT terminal by electric current input (4~20 mA) of OI-L terminal and O2 - voltage input (0
~ ±10V) of L terminal do ON analog outside input switching.
② According to AT terminal selection I049's command, I can choose input of O/OI/O2.
Note that the value of 02 selection I038 is 0(singleness).
