PARAMETER
(1) Selection of digital input [
Pr. 304
]
16bit (12bit) digital input is available when [
Pr. 304
9999
].
Use [
Pr. 304
] to select BCD code input ([
Pr. 304
] = 0,
2, 10, 12) or binary input ([
Pr. 304
= 1, 3, 11, 13]). For
BCD code, input data is read as decimal. For binary
input, input data is read as hexadecimal.
When 3 digits BCD code input or 12bit binary input is
selected, X12 to X15 signal of plug-in option FR-
A7AX is invalid.
When [
Pr. 304 = 2, 3, 12, 13
], output frequency is a
sum of digital input command and terminal 1
compensation input.
When switching the inputs e.g. between volume input
to perform manual operation and BCD code input to
perform automatic operation, set the BCD code input
to "0" under manual operation.
The priorities of the frequency setting are as follows.
"JOG
Multi-speed operation (RH, RM, RL)
PID (X14)
AU (terminal 4)
Digital command by
the FR-A7AX
terminal 2" (When digital input is
valid, terminal 2 is invalid.)
[Example] To input BCD code 6325
[Example] To input binary AB65

(2) Data read timing [
Pr. 305
]
When [
Pr. 305 = 0, 10
], the set frequency data entered
from the digital signal input terminals (X0 to X15) is
always imported independently of whether the DY
signal of plug-in option FR-A7AX is ON or OFF.
When [
Pr. 305 = 10
], filter is active for reading, and
compensation for a digital signal change timing of
each bit is available.
When [
Pr. 305 = 1
], the set frequency data entered
from the digital signal input terminals (X0 to X15) is
imported only when the DY signal is ON. The set
frequency data is not imported when the DY signal is
OFF. Therefore, even if the input status of the X0-X15
signal changes, the set frequency data before OFF of
the DY signal is valid.
Each terminal from X0 to X15 is all recognized as
OFF when the inverter is turned ON in terminal DY
OFF status.

entries are ignored during operation and the
previous inputs are used to continue operation. 0A

If binary input is changed to BCD code input with
