profile generator
Driving profile generator
The reference limiter is inserted upstream of the driving profile generator.
By way of the reference selector the reference sources are selected, and
thus indirectly in the driving profile generator the general ramp generator
or table-supported ramp generator. The driving profile generator genera-
tes the appropriate acceleration and deceleration ramps to attain the spe-
cified frequency reference. The braking ramp STPRx is effective throug-
hout the entire driving profile generator if it is activated with STPRx ≠ 0.
• Normal, non-table-supported driving sets (RSSLx ≠ FFTB):
Ramp generator with characteristic data sets, selection of characteri-
stic data set by way of characteristic data selector 650-CDSSL
• Table-supported driving sets (RSSLx = FFTB):
Driving sets from a stored table, selection of data sets by way of
table selector 624-TBSEL
Function Effect
• Setting of the acceleration
and deceleration ramps
• Setting of a smoothing of the
the start and end point of the
linear ramp
• Adaptation of the motor
dynamics to the application
• Reduced drive bucking
