9.2.28.1 Setpoint conditioning with stretching and gearbox factor
Stretching factor
Defines the ratio between the drive and the setpoint.
z The stretching factor evaluates the setpoint at DFSET-IN. DFSET-POUT outputs the result.
z The stretching 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.
z Relationship:
DFSET–POUT = DFSET–IN ⋅
DFSET–VP–DIV
C0533
Gearbox factor
Defines the transmission ratio of the drive. Enter the ratio of the drive.
z The gearbox factor evaluates the setpoint at DFSET-IN multiplied by the stretching factor.
DFSET-NOUT outputs the result.
z The gearbox factor results from numerator and denominator.
– Numerator is variable from analog signal source or fixed value by the code.
– Input of the denominator under C0033.
