Abstract
The invention relates to a method for determining a correction parameter for a measurement channel () which is connected to a connection terminal () of an electric motor () in order to measure a terminal voltage (U, U), characterized in that the connection terminal () is connected to a first potential via switching elements (T, T, T, T) for driving the electric motor (), after a steady state of the measurement channel () has been reached, the connection terminal () is connected to a second potential, which differs from the first, by changing over at least one switching element (T, T, T, T), the dynamic response of the measurement channel () is detected following connection to the second potential, and the correction parameter for the dynamic response of the measurement channel () is determined on the basis of the detected dynamic response of the latter.
