Descriptions of functions
10.33 Diagnostics
10.33.5 Diagnostics via STARTER
The diagnostic functions support commissioning and service personnel during
commissioning, troubleshooting, diagnostics and service activities.
Requirement
● Online operation of the STARTER commissioning tool.
Diagnostic functions
The following diagnostic functions are available in the STARTER commissioning tool:
● Specification of signals with the ramp-function generator
● Signal recording with the trace function
● Analysis of the control response with the measuring function
10.33.5.1 Function generator
The function generator is part of the STARTER commissioning tool.
The function generator can be used, for example, to perform the following tasks:
● Measuring and optimizing control loops.
● Comparing the dynamic response of coupled drives.
● Specifying a simple traversing profile without a traversing program.
The function generator can be used to generate various waveforms.
In the "Connector output" operating mode (r4818), the output signal can be injected into the
control loop via the BICO interconnection.
Properties
● The following freely parameterizable waveforms can be set:
– Square-wave
– Staircase
– Triangular
– Sinusoidal
– PRBS (pseudo random binary signal, white noise)
● An offset is possible for each signal. The power-up to the offset can be parameterized.
The signal generation starts after the power-up to the offset.
● Limitation of the output signal to the minimum and maximum value can be set.
