YM - Manual Tighten to Yield
This step guides the user until the yield point of the joint is reached.
Parameter | Description |
|---|---|
Target angle | If > 0, after detecting the yield point the operation continues until the angle reaches the Target angle value. If = 0, the operation stops when the yield point is detected. |
Ratchet time | Starts when the torque goes below the Rundown complete torque without reaching the 3rd percentage value. This allows the operator to release the torque for a while and recharge during the tightening operation. Default value: 5 sec. Minimum value: 0.1. Maximum value: 30 sec |
Linear slope coefficient | Defines the joint stiffness in the linear part of the curve. It is meant as torque/angle slope and is measured in Nm/°. Default value: 0.5. Minimum value: 0.1 (also suitable for very soft joints with a ratio less than 0.1). If the selected unit of measurement is different from Nm, the Linear slope coefficient must always be converted into Nm/°. |
Torque correction coefficient | When extensions are used, the wrench measurement might be compensated to show a more accurate torque value. To calculate the correction coefficient, please refer to How to calculate the Torque Correction Coefficient. When extensions are not used, Torque correction coefficient = 1. |
Angle correction | When extensions cause additional wrench bending, the wrench angle measurement can be compensated to show a more accurate angle value. When extensions are not used, Angle correction = 0. |
