Drives

The connection between the SINUMERIK 840Di and the drives is exclusively car-
ried out via the PROFIBUS-DP with Motion Control functionality in accordance with
the Drive Technology PROFIDrive (draft V1.4.2, 01st Sept., 00).
Essential features of the Motion Control functionality are:
•
Cyclic communication for a synchronous and equidistant transmission of the
setpoints and actual values between DP master (SINUMERIK 840Di) and DP
slave (drives).
•
Acceptance of the new setpoint into the drive controller time-synchronously for
all drives (speed/torque control mode).
•
Lateral communication for decentralized data exchange between the DP
slaves.
•
Acyclic communication in parallel to the cyclic communication, e.g. for the
transmission of parameter jobs, as well as for operator control and process
monitoring of drives.
Digital drive systems
The following digital drive systems are offered for the SINUMERIK 840Di:
•
SIMODRIVE 611
The converter system SIMODRIVE 611 with the closed-loop control modules
SIMODRIVE 611 universal and universal E, each with the optional plug-in
module "Motion Control with PROFIBUS DP" is offered as a drive system in
central design.
•
SIMODRIVE POSMO
The drive modules SIMODRIVE POSMO A and SIMODRIVE POSMO SI,
CD/CA, are offered as a drive system in distributed design.
Detailed information on the converter system SIMODRIVE 611 and the closed-loop
control/drive modules is to be found in the Catalog NC 60·2000/2001.
SIMODRIVE 611
SIMODRIVE 611
With the SIMODRIVE 611, Siemens offers a converter
system that meets highest requirements with regard to
the dynamic response, speed setting range and true
running properties in the drive system. Thanks to the
modular design, drive configurations with almost any
number of axes or main spindles can be implemented.
The modules of the converter system come in enclosed
and EMC-compliant housings acc. to DIN EN 60529
(IEC 60529). The electrical system has been
dimensioned acc. to EN 50178 (VDE 0160)
and EN 60204. CE Certificates of Conformity are
available.
