<p>The arrangement has a service switching device (S1) e.g. MOSFET, for supplying power to a direct current (DC) motor (M) from a power supply device (L) e.g. battery. A brake switching device (S2) e.g. MOSFET, engages a braking operation of the DC motor, and two detection devices e.g. resistors, detect an operating state of the service and braking switching devices. Two control devices e.g. locking devices, determine a change of respective operating state of the switching devices along the detected brake operating state.</p> |
