Ramp generator

A ramp generator is a functionality that is used in electrical generators and electric motors. Through the ramp-function generator, it is possible to limit a sudden change in setpoint acceleration so that load surges are avoided, which could harm the electrical machine. It is the specification of a high - trip time possible. Calculated these values ​​by the maximum speed of the parameter list. Some RFG also have the option of a so-called quick stop, the example after the actuation of emergency stop switch is a rapid guided standstill.

Implementation

Originally ramp-function generator were implemented with analog hardware. Today, the functionality is implemented mostly in software.
