This parameter selects the signal to be used as a feedback.
F
0:Tach 8÷25 V. The signal used as a speed feedback is included in the 8 ... 25V
voltage range; the voltage is supplied by a tacho and detected via terminal 20.
1:Tach 25÷80 V. The signal used as a speed feedback is included in the 25 ...
80V voltage range; the voltage is supplied by a tacho and detected via terminal
22.
2:Tach 80÷250 V. The signal used as a speed feedback is included in the 80 ...
250V voltage range; the voltage is supplied by a tacho and detected via terminal
23.
3:EnP/Nr. The signal used as a speed feedback is an enP/Nr output detected
via terminals 14 and 16, or via 9-pole D-connector CN2.
4:Armature. The signal used as a voltage feedback is the drive voltage output;
in case of a motor, the voltage feedback is the armature voltage. When the drive
operates according to an armature feedback with a resistive load, parameter
C051 (CurrLoopSel) should be set to the 0:PI operating default value.
In case of a tacho or enP/Nr feedback, the max. motor speed with a speed
reference equal to 100% is programmed through parameter P010 (nFdbkMax);
in case of an armature feedback, the max. voltage with a speed reference equal
to 100% is programmed through parameter P011 (VarmMax).

This parameter conveys information about the enP/Nr pulses/rev.
F
The values set in parameter C072 and parameter P010 should allow product
C072•P010 not to exceed 102.400k Hz (e.g. 1024 pulses/rev for 6000 RPM
max.) in order to avoid any drive failure.

D
This parameter conveys information about the transduction ratio of the tacho
F
used for the speed feedback according to a V / 1000 RPM unit of measure.
The values set on parameter C074 and parameter P010 should allow product
C074•P010 not exceed 25V if C070 = 0, 80V if C070 = 1, 250V if C070 = 2.
Otherwise, this will cause drive speed control failure.
