5.4.4.
Analog Input (2) and (3) Gain and Offset Adjustment
The sections {5.4.4.} and {5.4.5.} describe how to adjust analog input/output gain and offset automatically
with area S parameters.
Analog input (2) and (3) adjustment
●
Analog input (2) and (3) require an optional board such as <IO66-Z>.
When these optional boards are not used, the settings and adjustment described below are not required.
This section describes the procedures for changing the gain and offset of analog input (2) and (3), with the
following example of the analog input (2) gain and offset: L-9 and L-10 when <IO66-Z> is used.
Use the analog input (2) characteristics selection: L-07 and the analog input (2) adjustment: S-05 parameters.
For details of the analog input (2) characteristics selection: L-07, refer to {5.3.10. Area L}. For details
of the analog input (2) adjustment: S-05, refer to {5.3.14. Area S}. For details of how to change parameter
settings, refer to {4.2.3. Changing Parameter Settings}.
Analog Input (3) Gain and Offset Adjustment
●
For analog input (3) gain and offset, refer to the area L.
●
Specify setting items of the area L and area S to meet the analog input (3) gain and offset. Then, follow
the procedures below.
Warning
Short-circuit of terminals
●
Be sure to turn off the converter before short-circuiting the terminals.
Otherwise, it can result in a risk of electric shock.
Caution
Measuring voltage between terminals
●
Great care must be taken not to touch electrical wires and terminals when measuring voltage between
terminals.
Otherwise, it can result in a risk of electric shock.

1. When the [FNC] LED on the console is off, press the [MONI/FNC] key.
･
The [FNC] LED turns on, and a setting item appears in the seven-segment display. For example, immediately
after the converter is turned on, the first item of the basic setting area is displayed.
