7.4.1 Function generator (FG)
Using the function generator:
The influence of the higher–level control loops can be specifically
disabled
The dynamic performance can be compared for coupled drives
A simple characteristic (traversing profile) can be selected as set-
point and repeated, without having to program a traversing program
The function generator generates various types of setpoints (square-
wave, staircase, delta, PRBS or sinusoidal), and enters this setpoint,
corresponding to the selected mode, as current setpoint, disturbing
torque or as speed setpoint.
!
Danger
If the function generator is active, then traversing motion is not
monitored.
The following must be observed when starting the function generator:
The function generator is started as follows
– Setting P1800 = 1
The function generator is immediately started.
– Setting P1800 = 2 (from SW 8.1)
The function generator is started in synchronism – e.g. for gantry
axes if, in the n–set mode, the PROFIBUS control word
STW1.8=1.
The following starting conditions and enable signals must be avail-
able:
