<p>The drive has an energy supply device (5) i.e. switch-mode power supply, for transforming network-sided input voltage into output-sided small voltage. A control supply unit (18) is attached to a control device (17) of the supply device. The supply device is operated in an off condition switching mode when the supply device is separated from an electrical network, where the supply device is connected with the network and the control device is switched off when the supply device is operated in a release operating condition.</p> |
