Chapter 2 I/O ports
HA-680_V04 - 44 -
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).
Connection
Receive the signals by line receivers
(AM26LS32 or equivalent).
2-4-3 I/O port functions in torque control
This section describes I/O port functions in torque control.
CN2-1 Attained speed: HI-SPD (output)
Function
The output turns ON when the motor of actuator rotates at a speed greater than the value of [parameter]
[31: attained speed].
Logic change can be performed with “14: Output pin logic setting” in “Parameter.” With the
factory-shipped value, the output transistor is turned on when the speed is attained.
Connection
(1) The figure to the right shows an example of the [CN2-1
attained speed: HI-SPD] port connection.
(2) Configure the output circuit for the ports as follows:
Supply voltage: DC24V or less
Signal current: 40mA or less (per port)
CN2-2 Alarm: ALARM (output)
Function
The output turns OFF when the HA-680 driver senses an alarm. This signal is normal close (NC, b
contact).
Logic change can be performed with “14: Output pin logic setting” in “Parameter.” With the
factory-shipped value, the transistor is turned on during normal operation, and turned off when an error
is detected.
Connection
(1) The figure to the right shows an example of the [CN2-2
Alarm: ALARM] port connection.
(2) Configure the output circuit for the port as follows:
Supply voltage: DC24V or less
Signal current: 40mA or less (per port)
