Parameters
3-16 Reference 2 Source
Option: Function:
Select the input to be used for the
second reference signal. 3-15 Reference 1
Source, 3-16 Reference 2 Source and
3-17 Reference 3 Source define up to
three different reference signals. The
sum of these reference signals defines
the actual reference. See also
1-93 Thermistor Source.

NOTICE
This parameter cannot be adjusted
while the motor is running.
Select the reference input to be used for
the third reference signal. 3-15 Reference 1
Source, 3-16 Reference 2 Source and
3-17 Reference 3 Source define up to 3
different reference signals. The sum of
these reference signals defines the actual
reference.
The option [1] PM is not accessible, if
3-17 Reference 3 Source = [1] PM.
