The default value of 1.500 will produce 10 V output on the analog output (terminal 6)
when the feedback is at 100 % (Pr 54 Flux Feedback).

This parameter must be set to the same value as Pr 6.11 on Mentor II when used with
Mentor II. It defines the full scale current in amps.
This parameter must be set before Pr 78 is selected for Mentor II mode. If already in
NOTE
Mentor II mode [Pr 78 = 2.H (2) or 2.F (3)] a power cycle is required before the new
values will take effect.

In stand alone mode, setting this parameter will instruct the field controller to set-up its
flux loop gains automatically. If any voltage is detected on the armature voltage input
during the autotune then the unit will trip.
At the end of the autotune routine, Pr 77 is set to 0 (off) when Pr 81 = 0. If Pr 81 = 1,
then the controller remains in the enabled condition as controlled by the digital input.

This parameter sets the level at which field loss is detected and operates the fail relay in
Mentor II and standalone mode 100 % level = 150 % flux. 10 % flux / 1.5 = 6.7 the same
level as FXM5.
