# IT - Impulse Tighten to Torque / Loosen to Torque

Tools
IXB

Impulse steps are valid only for IPB-P tools.

Impulse Tighten to Torque

This step generates tightening pulses in the forward direction, until the torque target is reached.

Impulse Loosen to Torque

This step generates tightening pulses in the backward direction, until torque is below torque target.

Parameter | Description
--- | ---
Torque Target - Ts | Torque Target must range from 0 through the maximum torque of the tool.
Pulse Energy - Pe | Pulse Energy is used to control the amount of energy/current in each pulse. Pulse Energy must range from 10% through 100 %. Default value: 100%.
Auto Speed | On: The tool will run at impulse energy speed both when pulsing and not pulsing. The pulse energy speed will be used through the whole step. Off: The tool will run at the entered speed when not pulsing and at impulse energy speed when pulsing. Different speeds will be used within the step.
