Chapter 3 I/O ports
- 33 -
3-1-3 I/O port connections in the position mode
This section describes the connection between the I/O ports and a host in the position mode.
Inputs:
The HA-655 driver provides six ports
for inputs as shown in the figure to the
right.
◆ Specifications
Voltage: DC24V±10%
Current: 20mA or less
(for each port)
An input port circuit is shown in the
figure to the right. The ports marked
with (*) are available for absolute
encoder system only.
● Connection
The HA-655 driver does not provide
the power supply for input signals.
Connect a [+24V] power supply for the
signals to [CN2-1: input signal
common].
Outputs:
The HA-655 driver provides eight ports
for outputs as shown in the figure to
the right.
◆ Specifications
Port: Open collector
Voltage: DC24V or less
Current: 40mA or less
(for each port)
All ports are insulated by opto-isolators.
An output port circuit is shown in the
figure to the right.
● Connection
Connect output signals between their
respective output ports and [CN2-43:
output common] port.
