1-loop monitor screen when MFB AT is stopped
If a value of 1, 2, or 11 to 14 is set for "Output Type" in the PP (position
proportional) bank, the motor drive output status can be displayed by displaying
the 1-loop monitor screen of the relevant loop.
The figure below shows the appearance when MFB AT (MFB auto-tuning) is

Handling Precautions
•
If a value other than 1, 2, and 11 to 14 is set for "Output Type" in the PP
(position proportional) bank, the motor drive output status is not displayed on
the 1-loop monitor screen.
•
If the "Control method selection" setting in the PP (position proportional)
bank is set to 2 or 3, an MFB input wiring disconnection is not detected, and so
the MFB opening value appears white.
