Assignee: BECKHOFF AUTOMATION GMBH
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  B | IPC B  H

Claim 5:
6. The method as claimed in claim 4,
wherein a second setpoint current control signal for energizing the one drive coil with a first setpoint DC current is output to the stator having at least two drive coils as second control signal,
wherein a second voltage measurement signal is received as the second measurement signal, this representing a derived coil voltage of the drive coil energized with the first setpoint DC current after the second setpoint current control signal has been output,
wherein an inductive voltage component of the measured coil voltage of the first voltage measurement signal is calculated based on the second voltage measurement signal, wherein the resistive voltage component is subtracted from the measured coil voltage of the first voltage measurement signal in order to ascertain a coil voltage corrected for the resistive voltage component, and
wherein the carriage associated with the first measurement signal is identified as the first carriage or as the second carriage based on the ascertained corrected coil voltage.
