Chapter 2 I/O ports
HA-680_V04 - 18 -
z Monitor outputs
The HA-680 driver provides 6 ports of 3
signals for encoder monitoring as shown in the
figure to the right.
Specifications
The phase-A, -B, and -Z signals are
transmitted by line drivers (26LS31).
Connections
Receive the signals by line receivers
(AM26LS32 or equivalent).
2-2-3 I/O port functions in the position control
This section describes I/O port functions in the position control.
CN2-1 In-position: IN-POS (output)
Function
The signal is outputted as in-position ready when the deviation count becomes less than the value of
[parameter][22: in-position ready range]. The output may be used to confirm in-position ready signal,
etc. in a host.
Logic change can be performed with “14: Output pin logic setting” in “Parameter.” With the fault value,
the output transistor is turned on when the pulse-accumulated amount of the deviation counter is less
than the positioning completion range setting value.
Connection
(1) The figure to the right is a connection example of [CN2-1
in-position ready: IN-POS] port.
(2) Configure the output circuit for the ports as follows:
Supply voltage: +24V or less
Signal current: 40mA or less (per port)
CN2-2 Alarm: ALARM (output)
Function
The output turns OFF when HA-680 driver senses an alarm. The output is [NC contact (b-contact)
signal].
Logic change can be performed with “14: Output pin logic setting” in “Parameter.” With the fault value,
the transistor is turned on during normal operation, and turned off when an error is detected.
Connection
(1) The figure to the right is a connection example of [CN2-2
Alarm: ALARM] port.
(2) Configure the output circuit for the ports as follows:
Supply voltage: +24V or less
Signal current: 40mA or less (per port)
