4-7 External Monitoring Interface
4-7-1 Output Signal Specifications
This auxiliary connector (Located under top cover access plate) is used to output Torque, Angle, Current
& Speed signals to external equipment for monitoring purposes (X-Y Plotter, etc). The signals output from
this connector are the same signals that the system receives during the fastening process. This
connection is not required for the system to operate.
Pin No. Signal IN/OUT Description
1 EA2 OUT Disabled
2 EB2 OUT Disabled
3 ANGLE PULSE OUT Angle Pulse monitor output
4 ANGLE CW/CCW
OUT Angle direction output
5 GND Monitoring signal output GND
6 TD2 OUT Disabled
7 MON1 OUT Current Monitor output (10V = max. current)
8 MON2 OUT Speed monitor output (10V = max rotation speed)
9 TD1 OUT Analog torque output

Torque Voltage
（
Analog Voltage
）
Monitoring voltage is indicated from zero torque to full scale torque and the potential difference is
3.7V. The zero voltage is the voltage when the tool is unloaded (nothing connected to the output
shaft and no torque applied).
※
The zero voltage is not 0V.
（
Origin voltage range: -0.4V
～
+0.4V
）
Also the zero voltage of each tool may vary even for the same type of tool.
(Ex: If the zero voltage is -0.3V and the voltage at full scale torque is +3.4V, the voltage change is
⊿3.7V.)
ANGLE PULSE

Angle Pulse Signal
（
5V TTL Signal
）
Angle pulse will output one pulse for one degree of rotation (tool output square) if DIP SW1-4 is set
as default (OFF). (See 4-12-2 for DIP SW setting)
※
This may differ from the actual rotation angle
(The range of pulses when rotating the end of the tool once is 358
～
362pulses.)
ANGLE CW/CCW
：

：
Forward/Reverse Signal
（
5V TTL Signal
）
Outputs “HI” when the motor rotates in a clockwise direction and “LOW” when the motor rotates in a
counter-clockwise direction.
