Real tightening setting
It is set for a final tightening of the screws. (Numbers 1 to 50)
This tightening will choose from two types of torque method / angle method.
However, if it is set without torque sensor, selection methods tightening of No.00 is ignored.
(Or without torque sensor is set in the driver parameters.)
Method Exit conditions Judgment items
Torque
method
Until it reaches the cut torque, to rotate at a specified
speed. Angle from the snug torque, to determine the
time result.

judgment
Torque upper/lower limit
Time upper/lower limit
Angle upper/lower limit
Over time
Angle
method
From the snug torque, it will rotate at the specified
speed until it reaches the cut angle.
Torque, time, torque gradient also determined.
Gradient
decision
No torque
sensor
Do tighten similar to the torque method.
Calculate the torque to use the current value of the
motor.

Number is the number of the case to be set from GSK driver panel (Uxx-yy).
★
GKL should fix the value to 1.
☆
GSK should fix the value to 0.

Torque
method
Real tightening torque: This torque is the target of this tighterning. 0.1Nm
Angle
method
Stop torque: It is a stop torque to prevent the bolt from twisting. 0.1Nm
No02.
Torque
method Measurement start torque
★
: With this setting it begins measuring angle
and time.
0.1Nm
Angle
method Snag torque: It starts clamping plastic zone from this torque.
It also starts measuring angle and time
0.1Nm
No.03
Speed 1: It is the speed at the start in this process. Normally set about 50 to 80 rpm.
The tightening angle is also shown when tightening with only this process.
1rpm
No.04
Speed 1 End angle: It rotates at speed 1 until this set angle is reached.
When it reaches this angle, it switches to speed 2.
1 degree
No.05
Speed 2: This is the tightening speed in this process.
20 - 50 rpm is recommended.
1rpm
No.06
Over time:
When this set time elapses from the start of the process, the process is terminated.
It outputs overtime NG when it ends.
(It is excluded from time).
1sec
No.07 Torque upper limit: It sets the allowable upper limit of cut torque or stop torque. 0.1Nm
No.08 Torque lower limit: It sets the allowable lower limit of cut torque or stop torque. 0.1Nm
No.09
Torque
method
Stop angle
★
:
This is a setting to interrupt this process.
It functions to not break the machine when the torque does not reach the target
value due to some trouble.
1 degree
Angle
method Tightening angle: This is the rotation angle from the snug torque.
This sets the target angle.
1 degree
No.10 Before time: It delays the start of this process by the set value of time. 1msec
No.11
Time upper limit
★
: It sets the allowable upper limit of the time.
Unlike Overtime, this time is measured from the "measurement starting
torque"
or “Snag torque”.
1msec
No.12
Time lower limit
★
: It sets the allowable lower limit of the time.
Unlike Overtime, this time is measured from the "Measurement starting
torque"
or “Snag torque”.
