Function generator

The function generator for HLA is based on the existing functionality available for existing
drive types.
The function generator excites the drive with a periodic signal. The signal type can be
parameterized. External measuring instruments such as oscillographs can record the system
responses via DAC output sockets.
The following signals (operating modes) and signal types are available for the HLA:
● Signals (operating modes)
– Valve spool setpoint
– Velocity setpoint
– Force setpoint
● Signal type
– Square-wave
– Noise signal (only for signal output via DAC and external evaluation equipment for
– Staircase
– Sinusoidal
– Triangular
For an explanation of how to use the function generator, please refer to the SINAMICS S120
Commissioning Manual.
An overview of the function generator functions provided for HLA is given below, with only
the purely hydraulic-specific functionality for HLA described in detail.
