4-2 Precautions for Data Input
Note the following items when inputting the data from the terminals of the 3G3AX-DI Board.
Each input can be set within the data range of the Inverter for each parameter.
If the data input is out of range, a sequence error will be output, and the data input will be disabled
(previous data retained).
Be sure to input type codes in the order of MSB to LSB in the dividing input mode.
If the LSB code is input first, a sequence error will be output, and the data input will be disabled
(previous data retained).
To reset the sequence error, input a correct data again, reset the Inverter, or shut off the power.
In the dividing input mode, if the two data inputs are correct, the sequence error will be reset just
after the second input.
If a code other than the type code is input, a sequence error will be output
The data input is disabled when the Inverter trips. Reset the Inverter and input again.
Do not set each command source of the Inverter (A001, P031, b040, P032) to “Option (1 or 2)”
for the port without the DI Board mounted. (Option 1 for Board port 1, 2 for Board port 2)
Do not mount two DI Boards simultaneously. Doing so may result in malfunction.
The set values just after each command source of the Inverter (A001, P031, b040, P032) is set
to “Option (1 or 2)” are shown below.
Set frequency
0.00[Hz]
Acceleration/Deceleration time
(Set values of the Inverter)
Torque limit setting
0[%]
Position setting
0[pulse]
To input the set frequency in “rate”, use the following procedure.
Setting example
When setting the frequency in 75% of the maximum frequency, input
I
in
is as follows:
I

= 0.75

M
0.75: Rate

: Input data full scale
Note that
f
Hz that is actually set is calculated from the following formula:
The value ignoring the digit less than 0.001 Hz is used as the set frequency.
