SINUMERIK 840D Installation and Start-Up Guide (IAD) – 04.00 Edition
10.1 Instructions for use
The start-up software “Start-up tool” is used to configure and parameterize drive
systems on SINUMERIK 810D and 840D.
This tool can be used during initial start-up to enter the drive configuration and
assign drive parameters with standard data records as determined by the mo-
tor/power section combination. It also allows the drive and control data to be
archived on the PG or PC.
Further functions are also provided to assist optimization and diagnosis.
The measuring functions make it possible to evaluate the most important speed
and position control loop quantities as well as the torque control in the time and
frequency range on the screen without any external measuring instruments.
All important control loop signals on the position, speed and torque levels can
also be output with the DAC configuration on external equipment (e.g. oscillo-
scope, signal recorder) via test sockets on the 611D drive modules.
Apart from the usual method of optimizing the control loop machine data based
on transient response, i.e. time characteristics, a particularly powerful tool for
assessing the control loop setting is provided in the form of the integrated Four-
ier Analysis (FFT) function which can also be applied to analyze the given me-
chanical characteristics. This tool must be used if
S unsteady current, speed or position signal curves indicate problems with
stability
S only long rise times can be obtained in the speed loop.

The measurement diagrams can be archived via file functions, allowing ma-
chine settings to be documented and facilitating remote diagnostics.
