DOK-INDRV*-MP*-02VRS**-FK01-EN-P
4.4 SERCOS
interface
Brief Description
•
cyclical data exchange of command and actual values in equal time
intervals
•
data transfer via fiber optic cables
(except for converter in motor, in this case copper conductor)
•
service channel for parameterization and diagnosis
•
free configuration of telegram contents
•
synchronization between time command value takes effect and
measurement starting time of all actual values for all drives on a ring
•
overall synchronization of all connected drives to the control unit
•
cycle time:
min. 250/500
µ
s, max. 65 ms, granularity 2
(multiples of position clock 250
µ
s or 500
µ
s can be set)
•
SERCOS compatibility class C
•
baud rate: optionally 2, 4, 8 or 16 MBaud
•
automatic baud rate detection; active baud rate displayed in a
parameter
•
adjustable transmitting power (set via control panel)
•
max. number of configurable data in the MDT: 32 byte
•
max. number of configurable data in the AT:
32 byte
Note:
The number of configurable byte in the MDT/AT depends on
the relation of the position cycle time (P-0-0556, bit 2) to the
SERCOS cycle time.
SERCOS cycle time = pos. cycle time
→
max. length 16 byte
SERCOS cycle time > pos. cycle time
→
max. length 32 byte
For more detailed information please see the SERCOS
specification.
