2.1.2.1 Setpoint conditioning with stretch and gearbox factor
Stretch factor
The stretch factor defines the ratio for the drive running to its setpoint.
· The stretch factor evaluates the setpoints at nSet_v .
The result appears at nSetOut_v (16384 º 15000 rpm).
· The stretch factor results from numerator and denominator.
– Numerator: Variable value of nGainNominator.
– Denominator: defined under wGainDenom.
· Relationship:
nSetOut_v + nSet_v @
nGainNominator
wGainDenom
Gearbox factor
The gearing factor defines the gearbox ratio of the drive. Enter the ratio of the drive.
· The gearing factor evaluates the setpoints at nSet_v multiplied by the stretch factor.
The result appears at nSetSpeedOut_a (16384 º n
max
(C0011)).
· The gearing factor is formed from the numerator and denominator.
– Numerator: Variable value of nGearNominator.
– Denominator: defined under wGearDenom.
