Chapter 2 I/O ports
HA-680_V04 - 21 -
Can be set to CN2-8 FWD inhibit: FWD-IH (input)
Can be set to CN2-9 REV-inhibit: REV-IH (input)
● Function
[FWD inhibit]: open state (OFF) of the input inhibits forward rotation.
[REV inhibit]: open state (OFF) of the input inhibits reverse rotation.
Open states (OFF) of both inputs inhibit rotation.
The inputs may be used to limit the motion range of load mechanism between limit sensors.
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the fault value, the
prohibition state can be cleared with the input signal on (close).
● Connection
Connect “NC contact (b contact) signal.” Connect +24 V of
the input signal external power supply to “CN2-12 Input
signal common.”
Can be set to CN2-10 Clear: CLEAR (input)
● Function
(1) If an alarm exists:
This clears the alarm state, returns to operable state, and clears the deviation count to [0]. For
alarms that cannot be cleared, shut off the control power once, and turn it on again.
(2) If no alarm exists:
This clears the deviation count to [0]. At the same time, this clears the command count and the
feedback count. At the same time, the command pulse count is set to the same value as the
returned pulse count.
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the fault value, the
clear function works at the edge of the input signal ON.
● Connection
Connect “NO (a contact) contact signal.” Connect +24 V of the input signal external power supply to
“CN2-12 Input signal common.”
Can be set to CN2-8 or 10 Alarm clear: ALM-CLR (input)
● Function
This signal clears the alarm state and makes it ready for operation. However, the deviation count
overflow error becomes the operation ready state when alarm clear: ALM-CLR is inputted after deviation
clear: DEV-CLR is inputted.
When an alarm that cannot be cleared occurs, shut down the main circuit power supply and control
circuit power supply, remove the cause of the alarm, and then turn on the power again.
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the fault value, the
alarm clear function works at the edge of the input signal ON.
● Connection
Connect “NO (a contact) contact signal.” Connect +24 V of the input signal external power supply to
“CN2-12 Input signal common.”
