Torque step

The torque step is used for final tightening of the screw and to ensure that the correct torque is reached.

A	Max. torque
B	Target torque
C	Min. torque
D	Rescinding torque limit
E	Tightening angle trigger
F	Tightening angle
G	Min. angle
H	Max. angle

Parameter	Description
Speed	The tool speed is programmable within the valid range.
Target torque (B)	The target torque of the joint. This is also the final and peak torque of the step.
Direction	Use clockwise setting for normal tightening.
Vacuum enabled	Digital output to switch on an external vacuum pump.
Min. torque (C)	If the minimum torque value is not reached, the controller will display an error message.
Max. torque (A)	The maximum torque value must not be exceeded during this step. If the maximum torque is reached, the tool will stop and the controller will display an error message.
Rescinding torque limit (D)	This monitor parameter sets a lower limit for the torque in this step. If the torque, at any time, drops below this limit the tightening will stop with an error message. Setting this parameter to 0 will disable the rescinding torque monitoring.
Min. angle (G)	Angle that must have been reached when the step is finished.
Max. angle (H)	Angle that must not be exceeded prior to reaching target torque.
Step start delay	Delay from trigger to tool start.
Min. step time	Minimum time for the step. If not reached, the controller will display an error message.
Max. step time	Maximum time for the step. If exceeded, the controller will display an error message.
Tightening angle trigger (E)	Once the tightening angle trigger value is reached, angle counting begins for this step. If adjusted to a torque level where the screw is already seated, the gradient of torque vs. angle can give an indication for the clamping force within the joint (typical for metal joints).
Min. tightening angle	The tightening angle must exceed the min. tightening angle for the tightening to pass.
Max. tightening angle (G)	The maximum tightening angle (E) value must not be exceeded during this step. If the maximum tightening angle is reached, the tool will stop and the controller will display an error message.
