4-5-4 Description of I/O Signals
+24V
､
GND: SERVICE POWER SUPPLY PIN No.: TB3-2,3,11,12
User available power supply. (Limited to 0.5amp - in the case external power supply is not available)
Do not supply power to the [+24V] and [GND] terminals (24V DC service power supply) on the
controller.
Doing so may cause damage to the controller.
Do not use for more than 0.5A . When using the service power supply use shielded cable and keep
away from the AC wiring or other high electrical noise generating devices.
Attach a clamp filter to the power supply line. (example ZCAT2032-0930:TDK)
[Input Signals]
STOP: EMERGENCY STOP SIGNAL PIN No.: TB1-1
While this signal is input (
“ON” state), the controller is put in the STOP state.
In the STOP state, the output signals are cleared and the fastening operation cannot be started.
When the STOP signal is input during fastening operation, spindle motion stops and I/O will be
disabled. The fastening result data immediately prior to stoppage will be held.
The ON/OFF input state of this signal can be selected by the system option 1 [SYS 033].
When the ON contact is selected, the signal must be input to put in the STOP state. When the OFF
contact is selected, the signal must be INPUT (NC) to run a fastening cycle.
RESET: RESET SIGNAL PIN No.: TB1-2
When this signal is input, the display data and the output signals of the controller are cleared. Also,
when the signal is input during fastening operation, the fastening operation will stop.
REVERSE: TOOL REVERSE SIGNAL PIN No.: TB1-3
While the signal is “ON”, the spindle will turn in the direction opposite to the tightening direction (ex. If
the tightening direction is set to clockwise, the spindle will turn in the counter-clockwise direction
during Reverse operation and visa-versa).
The spindle unit will be in BUSY status while in Reverse operation.
START: FASTENING START SIGNAL PIN No.: TB1-4
The controller checks the WORK SELECT signal and SELF-CHECK signal at the rising edge
(“OFF”->
“ON”) of this signal and then starts the fastening process.
The rotation operation is started
when this signal is “ON”.
After the start of fastening and during the complete fastening process, the controller outputs the BUSY
signal,
the READY output signal is “OFF” and the START signal will no longer be accepted.
In the following conditions, th
e READY output signal is turned “OFF” and the START signal input
cannot be received: STOP condition, While fastening (when BUSY), While RESET is ON, Bypass
conditionor during an Abnormal condition.
When a START is input, the output judgment signal(s) and the previous fastening data are reset.
BYPASS: BYPASS SIGNAL PIN No.: TB1-5
While this signal is “ON,” the controller is put in the PROGRAM mode, the BYPASS signal is output,
and fastening cannot be started.
If the BYPASS mode is entered during fastening, the fastening process is stopped.
SELF CHECK: TORQUE TRANSDUCER AUTOMATIC CHECK SIGNAL PIN No.: TB1-6
When this signal is “OFF” (or unconnected) at the time of a START signal input, the zero voltage level
and CAL voltage level of the torque transducer is automatically checked before the fastening cycle
begins.
If the automatic check of the torque transducer
is not required, turning “ON” this signal at the time of a
START signal input, will cause this test not to be performed.
Once a Self Check is completed, the unit holds the check value until control power is turned off or
another check is performed.
