Remote I/O Functions
● Inputs (Inverter to PLC) Instance ID: 153 Decimal (99 Hex)
Note 1. A shaded box indicates that the bit is not used.
Note 2. Control remote I/O inputs and outputs are paired. When using control remote I/O, be sure
to set them together.
Note 3. Control remote I/O objects do not conform to the AC/DC drive profile, but are specially set
for this product.
Note 4. The P lock function (position lock or zero-servo function) is valid only for a 3G3FV Inverter
operating with flux vector control. This bit is not used with other Inverters or control modes.
Note 5. The output words (PLC to Inverter) allocated for the “control I/O remote I/O + multi-function
input monitor” function are the same as the output words allocated for the regular control I/O
remote I/O function. Just one byte is added to the allocated input words (Inverter to PLC).
■ Bit and Data Functions
The functions of all allocated output bits and data (PLC to Inverter) as well as input bits and data
(Inverter to PLC) in input words m through m+3 are the same as the regular control I/O remote I/O
function. Refer to 5-6-1 Control I/O Remote I/O Operation for details on these functions.
Only the functions of the inputs in input word m+4 are different, so those functions are described
here.
