A method for validating a signal system of an electrical drive is provided to control a delay between start-up of energisation and start-up of validation of a phase with a function of an energisation position. A method for validating a signal system of an electrical drive includes the steps of: monitoring a first signal indicating existence of a first parameter of the electrical drive; monitoring a second signal indicating existence of a second parameter of the electrical drive, which has a value other than 0 only when the first parameter exists; and validating the signal system when predetermined conditions of the first and second signals are satisfied. A predetermined flux threshold is supplied to a comparator(102) providing an output when a flux estimate exceeds the flux threshold. A phase current from a current converter is compared with a current threshold It in a comparator(103) in order to provide an output.
