Digital signal
input terminals
Used to input digital signals through either relays or
open collector transistors.
As the command signals are entered, speed or position
commands are selected using Pr. 360.

Data read timing
input signal
Used when a digital signal read timing signal is
necessary. Data is only read while terminals DY-SD are
shorted. By opening terminals DY-SD, the data before
opening is retained.

Use a micro current switching
contact relay for the relay
contact. A transistor with the
following specifications should
be selected for the open

When connecting the transistor output (open collector
output) of a programmable controller (PC), etc., connect
the external power common (positive) to this terminal to
prevent a fault occurring due to leakage current

Position data

When terminals DY-SD are open, the inverter does not import data. Therefore, if the input status of the X0-X11
signals change, the stop position data before opening of terminals DY-SD is valid.
Also, the position data is imported on the leading edge of the DY signal.
Note: Pr. 300 to Pr. 304 settings for the FR-A5AX are made invalid when the stop position is set to be specified
from outside the inverter (externally), with the FR-A5AP (orientation control option) fitted to the inverter and
when orientation control is used.
Pr. 300 to Pr. 305 of the FR-A5AX are made valid when the stop position is not set from outside the inverter.
