Stretching factor
The stretching factor defines the ratio with which the drive is to run faster
or slower than the setpoint.

DFSET-POUT = DFSET-IN ⋅
DFSET-VP-DIV
C0533
The stretching factor results from numerator and denominator.
ƒ The numerator (DFSET-VP-DIV) can be defined as a variable from the
analog signal source or as a fixed value from a code.
ƒ Enter the denominator under C0533.
 Note!
When calculating the stretching factor, the input signal at
DFSET-VP-DIV is not processed in a scaled mode. A signal of
100 % corresponds a count value of 16384.
Gearbox factor
The gearbox factor defines the ratio using which the drive speed can be
changed additionally.
The setpoint at DFSET-IN, multiplied by the stretching factor, is evaluated.
