Abstract
In a method for an electric pulse tool, which is configured to deliver torque pulses on an output shaft, in each of a plurality of periods, a current pulse is provided to an electric motor during a current-on time and a current feed is paused during a current-off time. The method includes retrieving a parameter reflecting an amount of reaction force that the operator of the electric pulse tool can be exposed to, and determining the current-off time based on the parameter. The determined current off time includes a first off interval until an end of a torque pulse and a second off interval after the end of the torque pulse. The second off interval is based on a width of the torque pulse, such that a wider torque pulse results in a wider off interval and a narrower torque pulse results in a shorter off interval.
