The selection of setpoint sources (P368) may be restricted by the type
of factory setting (P366).

Reference variables are intended as an aid to presenting setpoint and
actual value signals in a uniform manner. This also applies to fixed
settings entered as a "percentage". A value of 100 % corresponds to a
process data value of 4000h, or 4000 0000 h in the case of double
values.
All setpoint and actual value signals (e.g. set speed and actual speed)
refer to the physically applicable reference variables. In this respect, the
following parameters are available:
P350
Reference current
in A
P351
Reference voltage
in V
P352
Reference frequency
in Hz
P353
Reference speed
in rpm
P354
Reference torque
in Nm
In quick parameterization mode and in automatic parameter
assignment mode (P115 = 1(2,3)), these reference variables are set to
the motor ratings. In case of automatic parameter assignment, this
occurs only if the "Drive setting" converter status is activated.
The reference speed and reference frequency are always connected by
the pole pair number.

If one of the two parameters is changed, the other is calculated using
this equation.
Since this calculation is not made on download (see section 6.2.2),
these two quantities must always be loaded in the correct relationship.
If the setpoint and actual control signals are related to a desired
reference speed in rpm, P353 must be set accordingly (P352 is
calculated automatically). If a rotational frequency in Hz is to be used
as the reference (calculated using the pole pair number P109), P352
must be set.
