Abstract: A stepping motor driving device includes a table, a driving pulse control part, an interpolation number indicating part and a driving part. The table stores thinned data which is thinned from original data and designates a pulse width of a driving pulse relating to a slow-up control or a slow-down control of a stepping motor. The driving pulse control part sequentially reads the thinned data from the table at predetermined intervals, to interpolate the thinned data in accordance with a given interpolation number so as to generate interpolated data and to output the driving pulse with the pulse width designated by the thinned data or the interpolated data by sequentially using the thinned data and the interpolated date at predetermined intervals. The interpolation number indicating part indicates the interpolation number to the driving pulse control part. The driving part drives the stepping motor in accordance with the driving pulse.

Abstract: A method and a system are disclosed for preventing stepper motor control signals from being applied to a stepper motor drive circuit in order to stop a stepper motor when an interlock situation is present. A sequence of one or more control signals is generated by a motion control system and passed to one or more interlock logic gates connected in series. The interlock logic gates have an enable signal input which allows the control signals to pass through to the stepper motor drive circuit if the enable input signal is set to a logic level of “1”. On the other hand, the interlock logic gates will prevent the control signals from reaching the stepper motor drive circuit if the enable input signal is set to a logic level of “0”. The logic level of the enable input signal may be connected to a switch, relay, or an integrated circuit responsive to an interlock situation such as the opening of an access door.

Abstract: A stepping motor with an electrical activation circuit for electrical control of its exciter windings, is made as a driving motor and also as a braking motor with an adjustable braking action. The predefinable braking action is achieved passively without any current feed into the exciter windings. For this purpose a stipulated impedance with an adjustable duty factor can be connected to each exciter winding. One such stepping motor that is controlled in its braking action is used in an arrangement in which a strip or filament material can be transported braked from a storage.

Abstract: The method for driving a stepping motor for printers comprises the generation of first pulses (16A,16B) at n levels recorded in registers and representing a simulation of sinusoidal waves. The maximum level is applied during two consecutive microsteps to one of the phases of the motor, while the level of the other phase changes sign. During a motor stopping command, second pulses (VCA,VCB) are applied to the registers and to the two phases of the motor and are programmed so as to ensure, during the last microstep, an exact stopping position, such that all the stopping positions are kept apart by a whole number of half steps. Very precise, fast and noise-free printing is thus attained. The resolution is doubled, without any loss of precision or speed.
