7.5.9 0x604B vl_setpoint_factor
This object is used to configure the numerator and denominator of the
vl_setpoint_factor. The vl_setpoint_factor modifies the resolution or directing range of
the specified setpoint. It does not influence the velocity limit function and the ramp
function. A value of 0 must not be used.
7.5.10 0x604C vl_dimension_factor
This object is used to configure the numerator and denominator of the
vl_dimension_factor. The vl_dimension_factor is used to scale the user units so that
they can be used in a way that relates to the specific application.
Calculating the vl dimension factor:
Every user-specific velocity consists of a specific unit referred to as a specific unit of
time (e.g. 1/s, bottles/min, m/s,...). The purpose of the vl_dimension_factor is to convert
this specific unit to the revolutions/minute unit. A value of 0 must not be used.
Velocity [user-defined unit] / Dimension factor [rpm/user-defined unit] = Velocity [rpm]
The vl_target_velocity object is re-read every new profile cycle. It is scaled to
appropriate units using the vl_dimension_factor and vl_setpoint_factor objects and then
written to the drive preset reference 1 parameter (Pr 1.21).
