Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
7-2 Multi-function Input/Output Functions
This section describes the I/O signal settings for this inverter.
7-2-1 Multi-function Input Selection
You can use the function set by allocating the Multi-function Input 1 to 7 Selection (C001 to C007) to the
functions listed below.
The multi-function input terminals 1 to 7 can be set to either NO contact or NC contact individually in the
Multi-function Input 1 to 7 Selection (C011 to C017).
Do not allocate the same function to more than one multi-function input terminal. If you allocate the
same function to more than one multi-function input terminal by mistake, the function will be enabled for
the last allocated terminal only, and the previously allocated terminals are reset to 255 (no).
After allocating functions to the terminals 1 to 7, check that the set function is stored.
