Using the 20-HIM-A6 HIM with the LiquiFlo 2.0 AC Drive
Loading and Saving User Device Sets
Drive configuration, called user sets, can be saved and recalled for use at any time.
Up to three user sets can be saved in the LiquiFlo drive.
• To save the current drive configuration, select Save to Device User Set
under the ‘Device User Sets’ option of the MEMORY folder.
• To recall, or load, a user set, select Load from Device User Set under the
‘Device User Sets’ option of the MEMORY folder.
To identify which user set is active, select Show Active Device User Set under
the ‘Device User Sets’ option of the MEMORY folder. The name of the last user
set to be loaded into the drive is displayed. Active Set means factory defaults have
been restored.
Monitoring the Drive Using
the Process Display Screen on
the HIM The Process Display screen ( Figure 11 ) enables you to monitor up to three
process variables. You can select the display, parameter, scale, and text for each
process variable being displayed.
The ESC ‘soft key’ toggles between the Status screen and the Process Display
screen. In addition, the Process Display screen becomes active if no keys have
been pressed before the display timeout period expires. The timeout period is set
using HIM parameter 7 (User Dspy Time).
Displaying and Changing the
HIM Reference You can display the reference value that the HIM is sending to the drive by
pressing the REF ‘soft key’. The HIM reference can be used for the speed
reference.
To change the displayed reference, use the numeric keys along with the decimal
‘soft key’ for the decimal.
The value of the HIM reference is saved through a power cycle if drive parameter
192 (Save OIM Ref ) is set to save at power down.
TIP Changing the value of the HIM reference does not affect the value of any other
port reference.
