    摘要： Motor drives and control methods are presented for sensorless motor speed control in which inverter output currents are sampled from the inverter output, and a frequency modulation value is determined based on the current feedback and either one or more voltage commands or one or more voltage feedback signals. A speed or frequency setpoint is adjusted at least partially according to the frequency modulation value to provide an adjusted frequency or speed setpoint value that is then used in controlling the inverter to provide stability control to mitigate hunting or motor stoppage.

    摘要： In a device for moving a plurality of pressure rollers relative to respective counter rollers in a printing machine, it is possible to provide a simple design of this device, wherein, in a non-energy mode, the pressure rollers are arranged in a non-contact position. For this purpose, the device includes a plurality of movably supported pressure roller carriers that each support one pressure roller, the pressure roller carriers being movable between a contact position and a non-contact position. In this arrangement, each of the pressure roller carriers is biased in the direction of the contact position via a biasing unit. Furthermore, at least one actuation element is provided, the actuation element connecting at least two pressure roller carriers to a shared actuation device.
