 Torque voltage  (Analog voltage) 
Torque voltage expresses zero torque to CAL value by potential 
difference of 3.75V.  The origin is the voltage under nutrunner stop 
status. 
Note: Original voltage is not 0V.  (-2V~+2V range depending upon type 
though, also being different tool by tool even the type is the same) 
Example: Potential difference will be ⊿3.75V because full scale voltage 
becomes +3.25V when original voltage is –0.5V. 
 Angle pulse  (TTL signal 0V or 5V) 
Spindle unit outputs 1 pulse digital per 0.5°turning.  There is subtle 
difference from actual turning angles.  716~724 pulses per rotation of 
tool’s anvil (360 degree). 
 Forward reverse pulse (TTL signal 0V or 5V) 
  Spindle unit outputs HI for forward and LOW for reverse.

Chapter 5 Switching ON and trial operation 
5-1 Confirmation points prior to switching on 
① Confirmation of tool and spindle unit connection 
Tool and spindle unit connection is made by two (2) cables, 1 is power cable 
and the other is sensor cable.  Confirm that these 2 cables are connected 
with correct numbers and status of the connections.  In case any sag with 
cable is observed, check to see whether cable is stressed or not by physical 
confirmation (by hand).  Change the wiring arrangements if cables are 
stressed. 
 
② AXIS I/O cable wiring confirmation 
Make connection between external control equipment by AXIS connectors.  
Make sure that spindle unit input and output signals are connected with 
external control equipment.

======Chapter 5=============================================== 
< Instructions for power ON/OFF operation> 
Give waiting time (recommended 10 seconds ) when you switch on again spindle unit 
after switching off.    Unless you give waiti ng time or you switch on again spindle unit 
immediately after switching of f, following troubles can happen. 
 
z  Entry current protector circuit does not  function, abnormal current runs primary 
power circuit, then circuit  protector can be closed. 
z  Spindle unit power circuit detects the abnormality and close the circuit 
automatically.  Even if you switch on  spindle unit again due the protection, 
power circuit will not functi on (maintained OFF position) 
When spindle unit is not switched on again  due to the above reasons, wait for 5 
minutes or longer and switch on spindle unit again. 
 
③  Power voltage confirmation 
Confirm that the wiring has been made correctly by referring to 4-2 of 
Chapter 4 power plug connections.  Be careful because wrong pin 
number connections will cause burnout.    Confirm that power supply to 
spindle unit is 3-phase AC200~AC220V. 
 
Confirm the above points always before switching on 
  ④  Measure voltage after switching on to make sure of no voltage drop. 
Do this measurement when nutrunner is running and giving maximum 
torque (at the time of maximum power consumption). 
5-2  Initial setting data input 
Input data necessary to carry out tight ening only after switching on has been made 
exactly as per above instructi ons.    Spindle unit comes with  prior to shipment parameter 
setting as per customers’ specifications , however, change the setting as required by 
you. 
 
Do the following check after switching on spindle unit. 
 
In order to get spindle unit ready for operat ion, provide either main unit or spindle 
unit with operation preparation signal from  external control equipment (sequencer) 
and do the following check. 
 
1) Zero point confirmation  Press  RESET  switch of spindle unit and confirm that 
torque display gives value close to 0  but ALARM LED (red) is not lighting. 
 
2) CAL confirmation  Press CAL switch of  either main unit or spindle unit and 
confirm that ALARM LED (red) is not lighting. 
 
3) Manual reverse check  Press  REV  sw itch of main unit and confirm that 
corresponding tool is running one by one. 
①  Switch on non-operation (BYPASS) switch of all spindle units. 
② Switch off non-operation (BYPASS) switch of only 1 spindle unit and 
then switch on reverse (REV) switch of main unit to confirm that the 
BYPASS switched off tool is runni ng.  Do this check against all 
spindle units and tools.    Make sure to do this spindle by spindle. 
③  After above 2 points have been confirmed, change all BYPASS 
switch to RUN position and press reverse switch to rotate all 
spindles. 
4) Manual start confirmation  Press  START switch of main unit to do 
tightening. 
 
5) External start switch confirmation Confir m that start signal from external control 
equipment (sequencer) get sp indle unit started.

Chapter 6 Operation 
This system has 2 status, RUN and BYPASS. 
 
Under RUN status, spindle unit makes tightening and provides judgement display.  
An optional display panel displays tightening result data. 
 
Under BYPASS status, you can input setting value (parameter) spindle unit by an 
optional display panel but spindle unit does not do tightening operation. 
 
Use below-mentioned change over switch RUN/BYPASS to select status.
