Abstract: A method and apparatus to monitor the condition of an apparatus (e.g a variable speed drive), the apparatus comprising: a processor, a plurality of devices and a plurality of temperature sensors, each sensor associated with a device, the processor being arranged in use to: determine, for each of a plurality of sensors, the temperature of the associated device based on the temperature sensed by the sensor and the mode of operation of the device; compare the determined temperatures for each device with stored data relating to the mode of operation of the apparatus; and based on the comparison determine whether the apparatus is operating as expected in the mode of operation.
