Chapter 2 I/O ports
HA-680_V04 - 32 -
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).
Connection
Receive the signals by line receivers
(AM26LS32 or equivalent).
2-3-3 I/O port functions in the speed control
This section describes I/O port functions in the speed 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 default value,
the transistor is turned on in the speed achievement state.
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 default 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)
