Chapter 2 I/O ports
HA-680_V04 - 47 -
(I/O signal functions for torque 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.
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the
factory-shipped value, the alarm clear function works at the edge of the input signal ON.
◆ Connection
Connect [NO-contact signal (a-contact)]. Connect +24 V of the input signal external power supply to
“CN2-12 Input signal common.”
Can be set to CN2-10 or 11 external/internal common: CMD-CHG (input)
● Function
This signal switches between the “external command value” from the external device and the “internal
command value” set in “40: Internal torque command value” in “Parameter” inside the HA-680 driver.
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the
factory-shipped 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 CN2-11 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
factory-shipped 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.”
CN2-12 Input signal common: IN-COM (input)
● Function
The common for input signals CN2-7, 8, 9, 10, and 11. It provides the input signal external power supply.
◆ Connection
Connect +24 V of the input signal external power supply.
