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).
