Overview

Starting the
function
generator
7-714
Using the function generator:
S
The influence of the higher–level control loops can be specifically
disabled
S
The dynamic performance can be compared for coupled drives
S
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:
S
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.
S
The following starting conditions and enable signals must be avail-
able:
