In speed setpoint matching the NC is informed for parameterization of the axial
control and monitoring which motor speed in the drive corresponds to which
speed setpoint. Speed setpoint matching can be performed automatically or
manually.
It is possible to perform automatic speed setpoint matching if the drive supports
acyclic services on the PROFIBUS DP
Acyclic services on the PROFIBUS DP are supported by the following
SIMODRIVE drives:
– SIMODRIVE 611 universal/E
– SIMODRIVE POSMO CD/CA
– SIMODRIVE POSMO SI
and the value 0 must be entered in machine data:
S
MD32250: RATED_OUTVAL (rated output voltage) [ % ]
During start-up of the NC, speed setpoint matching between the NC and the
drive is then performed automatically.
Note
If automatic speed setpoint matching fails for one axis, the following message
is output on a traverse request for his 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) [ % ]
the NC assumes that speed setpoint matching will be performed manually.
The rated motor speed entered in axis-specific matching data:
S
MD32260: RATED_VELO (rated motor speed) [ rev/min ]
with reference to 100% must be equal to the speed evaluation entered in the
drive (P880):
S
P880: Speed evaluation PROFIBUS [rpm] (ARM/SRM) or
[ m/min ] (SLM)
