Auto/Manual Examples PLC = Auto, HIM = Manual
A process is run by a PLC when in Auto mode and requires manual control
from the HIM during set-up. The Auto speed reference is issued by the PLC
through a communications module installed in the drive. Since the internal
communications is designated as Port 5, [Speed Ref A Sel] is set to “DPI
Port 5” with the drive running from the Auto source.
Attain Manual Control
•
Press ALT then Auto/Man on the HIM.
When the HIM attains manual control, the drive speed command comes
from the HIM speed control keys or analog potentiometer.
Release to Auto Control
•
Press ALT then Auto/Man on the HIM again.
When the HIM releases manual control, the drive speed command
returns to the PLC.
