PARAMETERS

4.3 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

H

to 0F

H

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

If binary input is changed to BCD code input with 0A

H

to 0F

H

input, the set frequency becomes 0Hz.

(3) If 0 to 5V (0 to 10V) is input at the inverter terminal 1 from the external volume with the FR-A7AX fitted, 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>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.)
