ZERO MAGNIFICATION CHECK
：
Inspects the torque sensor zero point and magnification (Output voltage at 1/8 momentary maximum current).
※
When the zero magnification check is set on the program, the zero point of the torque sensor becomes zero
automatically. However, the value exceeding the one of the rating setting becomes “Zero magnification NG”.
APPLICABLE TO QC PERSONAL COMPUTERr
：
Automatic gain of the tightening data and tightening waveform (Simultaneous use with a printer is not possible.)
※
Tightening data
：
”Machine No.”, “Axis No.”, “Screw No.”, “Date”, “Time”, “Program No.”, Pretightning torque,
Pretightening angle, Reverse time, Reverse angle, Final tightening torque, Final tightening time, Final
tightening angle, Final tightening snag torque, Gradient, Rotation torque judgement, Unit No., Engine No.
※
Tightening waveform
：
Waveform from the final tightening snag torque to the finish,
APPLICABLE TO ID CONTROLLER
：
It is possible to transfer the engine number, set the calendar and transmit the result data by connecting the
interface unt and ID controller via serial communication. (Exclusive use with a printer.)
APPLICABLE TO PRINTERS
：
Connects with a printer through Centronics interface. Setting data and tightening result can be printed .
（
Exclusive use with a QC personal computer and ID controller
）
TIGHTENING ANGLE SAMPLING OPERATION
：
Operation to rotate the screw in the tightening direction at a constant speed and then stop when it reaches the
preset torque, in order to measure the screw length.The angle form the start to stop is read through the personal
computer vommunication. This is not the operation on the program.
（
Execcutable only from the personal
computer and SIO
）
END, STOP
：
During tightening operation (rotanion, pretightening, reverse tightening and final tightening), the operation may
be finished to stop when the condition is matched. This point that the condition matches (during the motor
running)
is defined as “End” and the point actually the motor stopped is defined as “Stop”. Most NG
determination is executed after “Stop” is established.
