The RD30 Crane Drive has extensive functionality for efficient and reliable use in cranes. At the same time, the ease of installation makes it an attractive solution for modern crane systems.
Braking resistors are used to remove excess energy when the drive is operating in generator mode, especially when performing rapid braking operations. It is important to note that the RD30 frequency converters up to 55 kW have a built-in reinforced brake unit for connecting resistors. This ensures efficient and safe operation of the crane system when rapid and controlled braking is required.
It is also possible to use the VEDA-in RD05 and VEDA-in RD11 series to drive the crane movement.
