Instructions

(1) Acceleration/deceleration time
When the frequency is set with the digital input signal, the acceleration/deceleration time is the period
of time required to reach the Acceleration/deceleration reference frequency set in Pr. 20. This is the same
as when using the analog signal input.
(2) There are the following restrictions on the digital input signal:
When the signal is used to enter a BCD code, 0A
previous inputs are used to continue operation.
If binary input is changed to BCD code input with 0A
(3) If 0 to 5V (0 to 10V) is input at the inverter terminal 1 from the external potentiometer with the FR-A7AX
fitted in the FR-A700/F700 series, the inverter operates at the frequency obtained by adding the FR-
A7AX BCD code input and the compensation input from terminal 1 only when "2, 3, 12 or 13" is set in
Pr. 304.
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.
(4) The priorities of the frequency setting are as follows.
JOG> Stop-on contact (RT, RL) > Multi-speed operation (RH, RM, RL) > PID (X14) > AU (terminal 4)
> Pulse train input > Digital command by the FR-A7AX > terminal 2
* When digital input is valid, terminal 2 is invalid.
to 0F entries are ignored during operation and the
H H
to 0F input, the set frequency becomes 0Hz.
