3-17 Reference 3 Source
Option: Function:
Select the reference input to be used for the third reference signal. par. 3-15 Reference 1 Source ,
par. 3-16
Reference 2 Source and par. 3-17 Reference 3 Source define up to three different refer-
ence signals. The sum of these reference signals defines the actual reference.
This parameter cannot be adjusted while the motor is running.
