Chapter 2 I/O ports
HA-680_V04 - 24 -
(I/O signal functions for position control)
◆ Connection for open collector commands and +24V power supply
(1) Connect FWD command to [CN2-15: FWD-] and [+24V].
(2) Connect REV command to [CN2-17: REV-] and [+24V].
(3) Connect [+24V] of external power supply to
[CN2-18: +24V].
(4) Plan the command circuit for the ports as follows:
Supply voltage: +24V±10%
Signal current: 16mA (less than 20mA)
◆ Connection for open collector commands and
+5V power supply
(1) Connect FWD command to [CN2-14: FWD+] and
[CN2-15: FWD-].
(2) Connect REV command to [CN2-16: REV+] and
[CN2-17: REV-].
(3) Open [CN2-18: +24V].
(4) Plan the command circuit for the ports as follows:
Supply voltage: +5V±10%
Signal current: 16mA (less than 20mA)
Note: Use resistances to suppress rush current to
command circuits (FWD- and REV-).
● Connections for Line driver system
(1) Connect FWD command to [CN2-14: FWD+]
and [CN2-15: FWD-].
(2) Connect REV command to [CN2-16: REV+]
and [CN2-17: REV-].
(3) Open [CN2-18: +24V].
Note: Use line drivers of EIA-422A standard. If
you want to use line drivers of other
standard, technical arrangement with us
is required.
The connections are deferent by the supply voltage.
The pin numbers to be connected are deferent by the supply voltage of [+5V] or [+24V].
The wrong connection may damage the driver.
