Input data
Input
processing
Bias, gain, filter, increment/decrement limiter, zero-hold, polarity changeover,
offset, and dead zone settings are possible individually.
Refresh cycle 1 ms
Function
allocation
Set with functional codes E72 and E73.
Output data
Output
processing
Bias and gain settings are possible individually. Filter settings for all AO functions
are possible.
(1) Input
Two analog input points ([Ai3] and [Ai4]) can be freely set to the following functions.
The functions are set with functions codes E51 through E52. If the same function is assigned to both
[Ai3] and [Ai4], Ai3 takes precedence. If the same function is assigned to [Ai1] - [Ai4], [Ai1] has
priority.
For the Ai functions, refer to Chapter 4, E49 to E52 (Terminal Ai Function) in the FRENIC-VG User's
Manual (Unit Type / Function Codes Edition).
(2) Output
Two analog output points ([AO4] and [AO5]) can be freely set to the following functions.
The functions are set with functions codes E72 and E73.
For the Ao functions, refer to Chapter 4, E69 and E73 (Terminal Ao Function) in the FRENIC-VG User's
Manual (Unit Type / Function Codes Edition).
