METHOD AND ARRANGEMENT FOR MONITORING SIGNALS

摘要

The invention relates to a method and to an arrangement for monitoring signals which are guided to a multi-phase motor by an end stage and the pulse width thereof is controlled by a controller.The total of the pulse widths of the signals of each phase is measured by, respectively, a counter, respectively for a predetermined programme flow in the controller. The meter reading is read by a counter according to a predetermined period of time and an error signal is produced if the total amount of time exceeds a predetermined tolerance range.
