4-5-4. Description of I/O Signals
+24V､GND: SERVICE POWER SUPPLY PIN No.: TB3-2,3,11,12
Do not supply power to the [+24V] and [GND] terminals (24V DC service power supply) on the Unit.
Doing so may cause damage to the product.Do not use it more than 0.5A. When use the service
power supply; the thing using the shield cable.Wire it from the power lines of other apparatuses apart.
Attach a clamp filter to the power supply line. (example ZCAT2032-0930:TDK)
(1) Input Signals
STOP: EMERGENCY STOP SIGNAL PIN No.: TB1-1
While this signal is input in the “ON” state, the Unit is put in the STOP state.
In the STOP state, the output signals are cleared and the fastening operation cannot be started.
Also, when the STOP state is entered during the fastening operation, although the fastening
operation will be stopped, the fastening result data immediately prior to stopping will be held.
For the “ON” state of this signal, an A contact or a B contact can be selected by the system option 1
[033].
When the A contact is selected, the signal is “OFF” in the open contact state and “ON” in the closed
contact state.
RESET: RESET SIGNAL PIN No.: TB1-2
By setting the RESET signal to “ON,” the fastening result judgment output signal is cleared.
The fastening operation cannot be started when the RESET signal is “ON.” Also, when the RESET
signal is set to “ON” during the fastening operation, although the fastening operation will be stopped,
the fastening result data immediately prior to stopping will be held.
REVERSE: TOOL REVERSING SIGNAL PIN No.: TB1-3
While this signal is input in the “ON” state, the tool rotates in reverse.
To ensure reverse rotation of the tool, set this signal to “ON” after the READY signal is set to “ON.”
START: FASTENING START SIGNAL PIN No.: TB1-4
When the START signal is raised (“OFF” → “ON”: 100msec), the fastening operation is started.
The fastening operation is stopped when this signal is set to “OFF.”
If operation stops before 1ST torque or 1ST angle is detected, the fastening data will not be saved.
After the start of fastening, the Unit is put in the BUSY (fastening) state.
Also, under the following conditions, fastening cannot be started even if the START signal is raised.
During the fastening operation (when the BUSY signal is “ON”)
When the ABNORMAL signal is “ON” or the RESET signal is “ON”
When another START signal is “ON” or the REVERSE signal is “ON”
When the Unit is in the BYPASS mode
(during editing of set values, during communication, etc.)
When the Unit is in the STOP state
BYPASS: BYPASS SIGNAL PIN No.: TB1-5
While this signal is “ON,” the Unit is put in the PROGRAM mode, the BYPASS signal is output, and
fastening cannot be started.
Also, when the BYPASS mode is entered during the fastening operation, although the fastening
operation will be stopped, the fastening result data immediately prior to stopping will be held.
Also, initialize the count number stored in the controller to 0,
PLC I/O output signals [BATCH OK] and [BATCH SEQ END] signals are turned OFF.
