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. Because the internal
communication 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.
• 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.
PLC = Auto, Terminal Block = Manual
A process is run by a PLC when in Auto mode and requires manual control from
an analog potentiometer wired to the drive terminal block. The auto speed
reference is issued by the PLC through a communications module installed in the
drive. Because the internal communication is designated as Port 5, [Speed Ref A
Sel] is set to “DPI Port 5” with the drive running from the Auto source. Since the
Manual speed reference is issued by an analog input (“Analog In 1 or 2”), [TB
Man Ref Sel] is set to the same input. To switch between Auto and Manual,
[Digital In3 Sel] is set to “Auto/Manual.”
• Attain Manual Control
–
Close the digital input.
With the input closed, the speed command comes from the pot.
• Release to Auto Control
–
Open the digital input.
With the input open, the speed command returns to the PLC.
