Function
This parameter selects the reference source when DC power supply (PV field) is active.
If 12: MPPT, the motor speed reference is generated by the internal regulator in order to guarantee
operation at the Maximum Power Point Tracking of the PV field.
NOTE
If parameter C143 is set other than 12: MPPT, the equipment might not run correctly.

Function
This parameter selects the reference source when AC power supply (optional) is active.
If set to 1: REF, the motor speed reference is taken from REF analog input. Factory setting: +10 V DC
to REF input produces a speed reference for the motor equal to the speed value set in parameter
C029
(see section 2.6.4).
