Abstract:
There is provided a motor drive comprising: a temperature sensor arranged to sense a temperature of the drive; a braking resistor; switching means arranged when activated to cause current to flow to the braking resistor; and controlling means arranged to activate the switching means when the sensed temperature falls below a predetermined threshold. There is also provided a method of controlling a temperature of a motor drive comprising a braking resistor. The method comprising comprises: monitoring a temperature of the drive; and activating switching means to cause current to flow to the braking resistor when the monitored temperature falls below a predetermined threshold.
