Abstract
On an electronic carriage brake for a drawing machine, the power stage (18) associated with a brake magnet (12) for a considered co-ordinate direction is triggered directly via the output signal from a comparator (24), to which the measured position signal (20) and the nominal-value signal (26) are applied, as well as additionally via a monostable trigger circuit (30) which is triggered by the output signal from the mentioned comparator (24).
Claims15
An electronic carriage brake intended for a drawing machine and provided with an electrically controllable brake magnet and with a control system which is associated with the brake magnet and comprises:
- a position sensor which co-operates with the carriage, a unit for inputting a desired position nominal value, a comparator to which output signals from the position sensor and from the input unit are applied, and a power stage which is connected to an output of the comparator for driving the brake magnet, characterised in further comprising a monostable trigger circuit (30), a clock terminal of which receives the output signal from the comparator (24), and an OR element (28) which combines an output signal from the monostable trigger circuit (30) and the output signal from the comparator (24), both of which output signals serve for triggering the power stage (18), an output of the OR element (28) being connected to an input terminal of the power stage (18).
