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 of the PP (position proportional)
bank is set to 2 or 3, MFB AT is not executed.
•
If an MFB input wiring disconnection is detected, MFB AT does not start. Also,
if an MFB input wiring disconnection is detected after starting MFB AT, the
MFB AT process is stopped.
