Abstract
The invention relates to a circuit arrangement for controlling electric motors of an industrial truck, comprising an electronic control stage with a main board (16) and an exchangeable board (22), and comprising a power-output stage (14). The exchangeable board (22) can be detached with little effort from the main board (16) that is fixed inside a case (12). The exchangeable board (22) comprises a group of selected control stage components (24) for which, statistically, a greater need for exchanging and/or a greater need for testing and/or a greater need for variants to be kept ready on the side of the producer exists than for the components (18) of the main board (16).
