SINUMERIK 840Di sl Manual (HBIsl) -- 01/2007 Edition
11.5.15 Speed setpoint matching
In the case of s peed setpoint comparison, the NCK is informed, which speed
setpoint corresponds to which motor speed in the drive, for parameterizing the
axial control and monitoring. Speed setpoint matching can be performed auto-
matically or manually.
Automatic speed setpoint matching can be performed for the following drives:
-- SINAMICS S120
-- SIMODRIVE 611 universal/E
-- SIMODRIVE POSMO CD/CA
-- SIMODRIVE POSMO SI distributed servo drive
If the value 0 is entered in machine data
S MD32250: RATED_OUTVAL (rated output voltage) [%]
(default value on SINUMERIK 840Di sl), the speed setpoint is automatically
matched between the NCK and drive when the NCK is started up.
Note
If automatic speed setpoint matching fails for one axis, the following message
is output on a traverse request for this axis:
S Message: ”Wait, axis enable missing”
This axis and any axes that interpolate with it are not traversed.
If a value not equal to 0 is entered in machine data:
S MD32250: RATED_OUTVAL (rated output voltage) [%]
no automatic speed setpoint matching is performed. Speed setpoint matching
must be performed manually using the following axis --specific machine data:
S MD32250: RATED_OUTVAL (rated output voltage) [%]
S MD32260: RATED_VELO (rated motor speed) [rev/min]
The rated motor speed entered in axis --specific machine data: MD32260:
RATED_VELO with reference to 100% must be equal to the speed evaluation
parameterized in the drive:
MD32260: RA TED_VELO

Because ADI4 does not support acyclic services on the PROFIBUS DP, manual
speed setpoint matching must
be performed.
