4-56 Parameter Adjustments & Application Considerations
Using the PF Key to Move to the Manual Control Level
1. When the PF Setting parameter is configured to A-M (Auto/Manual),
pressing the PF Key for at least one second while in the adjustment or
operation group will change the mode to manual mode and move to the
manual control function group. During manual operation it is not
possible to move to any displays other than PV/MV (Manual MV).
Press the PF Key for at least one second from the PV/MV display in the
manual control mode to change the mode to automatic mode, move to
the operation function group, and display the top parameter in the
operation function group.
2. For 900-TC8 and 900-TC16, when MANU (Auto/Manual) is selected
for an event input, the Auto/Manual Switch parameter is not displayed.
In that case, switching between auto and manual mode is executed by
using an event input.
Auto/Manual Select Addition
The Auto/Manual Select Addition parameter must be configured to ON in the
Advance Setting function group before it is possible to move to manual mode.
The default is OFF.
Note: 1. Priority of Manual MV and Other Functions
Even when operation is stopped, the manual MV is given priority
over other functions. Auto-tuning and self-tuning will stop when
manual mode is entered.
Note: 2. Manual MV and SP Ramp
If operating, the SP ramp function will continue even when man-
ual mode is entered.
