Chapter 2 I/O ports
HA-680_V04 - 36 -
(I/O signal functions for speed control)
Can be set to CN2-10 Alarm clear: ALM-CLR (input)
Function
This signal clears the alarm state and makes it ready for operation. 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.
Connection
Connect “NO (a contact) contact signal.” Connect +24 V of the input signal external power supply to
“CN2-12 Input signal common.”
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the default value,
the alarm is cleared at the edge of the signal ON.
Can be set to CN2-10 or 11 external/internal command: CMD-CHG (input)
Functions
This signal switches between the “external command value” from the external device and the 4 “internal
command value” set in “32: Internal speed command value” in “Parameter” inside the HA-680 driver.
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the default value,
the operation is as follows.
Open: external command value
Close: internal command value
Connection
Connect +24 V of the input signal external power supply to “CN2-12 Input signal common.”
Can be set to CN2-10 or 11 Speed limit: SPD-LMT (input)
Function
This signal limits the speed to the value set in “16: Speed limit” in “Parameter.”
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the default value,
the speed limit state occurs when the input signal is 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 CN2-11 Current limit: CUR-LMT (input)
Function
This signal limits the current below the value set in “17: Forward rotation current limit” and “18: Reverse
rotation current limit” in “Parameter.”
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the default value,
the current limit state occurs when the input signal is on.
Connection
Connect [NO-contact signal (a-contact)]. Connect +24 V of the input signal external power supply to
“CN2-12 Input signal common.”
