Moeller DF51 - Analog Output (AM)

Analog output (AM)
The AM terminal provides the output frequency or the motor
current as voltage signal (0 to +10 V). The reference potential is
0 V (terminal L).
The selection between the frequency and motor current indication
is made with PNU C028.
Analog output signal
For signal compensation, PNU b080 (gain) and PNU C086 (offset)
are used. The signal accuracy after compensation is about g5%.
