9.4.29 Virtual master axis [832]
Integrator for the
virtual master axis
using the comfort
ramp-function
generator
9-84
Synchronization function U603 U657
The synchronization function [835.6] defines whether the
synchronization block operates with
1:1 synchronization
Gear synchronization
Cam
The function can be set by parameter or binector. Parameter U657
defines the binectors for the switchover.
You will find detailed information on the virtual master axis in
"Configuring and testing the virtual master axis" in the section entitled
"Commissioning the technology".
If the machine speed is to be specified as a percentage value (not in
LU), it is recommended to use the comfort ramp-function generator in
the free blocks [790], which produces very accurate speed and
acceleration precontrol values (KK571 and KK572). From software
release V1.3 and higher, a special position integrator is provided in the
function diagram sheet [791] for implementing a virtual master axis
using the comfort ramp-function generator. If these two function blocks
are used connected in series, the virtual master axis shown on sheet
[832] is no longer required.
