3.5.30.1 Setpoint conditioning with stretch and gearbox factor
Stretch factor
Defines the ratio between the drive and the setpoint.
l The stretch factor evaluates the setpoint at DFSET−IN. DFSET−POUT outputs the result.
l The stretch factor results from numerator and denominator.
– Numerator is variable from analog signal source or fixed value by the code.
– Input of the denominator under C0533.
l Relationship:
DFSET–POUT + DFSET–IN @ DFSET–VP–DIV
C0533
Gearbox factor
Defines the gearbox ratio of the drive. Enter the ratio of the drive.
l The gearbox factor evaluates the setpoint at DFSET−IN multiplied by the stretch factor.
DFSET−NOUT outputs the result.
l The gearbox factor results from the numerator and denominator.
– Numerator is variable from analog signal source or fixed value by the code.
– Input of the denominator under C0033.
l Relationship:
DFSET–NOUT + Reckfaktor @ DFSET–RAT–DIV
C0033
DFSET–NOUT + DFSET–IN @ DFSET–VP–DIV
C0533
@ DFSET–RAT–DIV
C0033
Tip!
With C0530 the gearbox factor and the DFSET−N−TRIM values can be deactivated as a basis for the
setpoint angle. In the case of C0530 = 1, only the stretch factor is used for calculating the setpoint
angle.
