* How to use terminal DY (when the stop position is specified from outside the inverter (externally) ).
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.
REMARKS
Pr.300 to Pr.305 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.
Remarks
Use a micro current
switching contact relay for
the relay contact.

ORIENTATION CONTROL—A500(L)
Description
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.
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.
Common terminal for digital signal input terminals and data
read timing signals.
When connecting the transistor output (open collector
output) of a programmable controller (PLC), etc., connect
the external power common (positive) to this terminal to
prevent a fault occurring due to leakage current.
