An electric pulse tool is configured to deliver torque in pulses on an output shaft thereof and includes an electric motor to drive the output shaft. The electric pulse tool is configured to, for each period, provide a current pulse to the electric motor during a current-on time interval, pause a current feed to the electric motor after the current-on time interval until an end of a torque pulse, determine a width of the torque pulse, and continue pausing the current feed to the electric motor during a pause interval from the end of the torque pulse. The pause interval is determined based on the width of the torque pulse such that a wider torque pulse results in a wider pause interval and a narrower torque pulse results in a shorter pause interval.

The present disclosure provides a device for controlling a position based on a programmable logic controller (PLC), the device comprising: a motor driving module; an input module; and a control module, wherein the control module includes: a profile creation unit configured for creating the position profile based on the position command when a first position calculation interrupt is generated in a first position control period; a pulse calculation unit configured for calculating a number of outputs of the driving pulse to be output in a second position control period following the first position control period based on the position profile; and a driving controller configured for outputting the driving pulse having the number of outputs calculated by the pulse calculation unit to the motor driving module when a second position calculation interrupt notifying a start time-point of the second position control period is generated.

A motor controller capable of more reliably starting a stepping motor even if a predetermined drive power is supplied to the stepping motor, and to a control method for the stepping motor is provided. The motor controller driving a stepping motor detects that the stepping motor is in a step-out state after a start operation of the stepping motor is performed. If predetermined determination conditions are satisfied, when it is detected that the stepping motor is in a step-out state, it is determined that a restart operation of the stepping motor is performed, and the stepping motor is restarted.
