Chapter 2 I/O ports
HA-680_V04 - 22 -
(I/O signal functions for position control)
Can be set to CN2-9 or 11 Deviation clear: DEV-CLR (input)
Function
This signal clears the deviation counter and sets the deviation pulse count to “0.” 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
deviation clear function works at the ON 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 CN2-10 or 11 Speed limiting: SPD-LMT (input)
Function
This signal limits the speed to the value set in “16: Speed limit” in “Parameter.”
If you continue to input a command pulse over the limit speed, the “deviation counter overflow” alarm
occurs. This alarm can be cleared by “CN2 Clear: CLEAR” or “CN2 Alarm clear: ALM-CLR.” Be careful
when you release it because the speed increases instantaneously when the limit is released while the
speed is limited.
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the fault 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 limiting: 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.”
If you continue to input a command pulse while the current is limited and no acceleration to the speed is
possible because the current is limited, the “deviation counter overflow” alarm occurs. This alarm can be
cleared by “CN2 Clear: CLEAR” or “CN2 Alarm clear: ALM-CLR.” Be careful when you release it
because the speed increases instantaneously when the limit is released while the current is limited.
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the fault value, the
current 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.”
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.
