Chapter 5: Program Parameter Descriptions
5-1 Defining Program Parameters
Parameter 0 – Exit to Running Mode
When parameter 0 is selected in Parameter-Selection Mode, the unit will return to Running
Mode and display the running value. This should be selected once changes to parameters are
completed.
Parameter 10 – Operating Mode
This parameter defines the operating mode for the entire unit. There are two basic modes of
operation, master and follower. In master modes, the unit controls the load using rate or time
units. In follower mode, the unit controls the load in percentage of master rate.
Mode 1 – Master, Rate Mode
In Rate Mode, the drive displays in user-defined rate units such as RPM, Gallons per
Hour, or Feet per Second.
Mode 3 – Follower Mode
In Follower Mode, the drive displays in percentage units, where 1000 equals 100.0
percent of the master rate. For example, if the display indicates 985, 98.5, or 9.85, the
drive will attempt to run at exactly 98.5% of the master rate. Display settings are
always entered ignoring the decimal point's position.
Parameter 13 – Decimal Point (DP) Position
This selects the format of the display with respect to the decimal point’s position. This
parameter does not affect the value entry for other parameters. For example, if the user
desires to display 10.00 at 300RPM, then parameter 30 would be set to 1000, parameter 31
would be set to 300, and parameter 13 would be set to 2.
Mode 0: Fixed XXXX
Mode 1: Fixed X.XXX
Mode 2: Fixed XX.XX
Mode 3: Fixed XXX.X
Mode 4: Fixed XXXX.
Parameter 14 – Keypad Mode
This parameter selects the operating mode of the front-panel push buttons. In some
applications, increasing or decreasing the scroll rate provides the user more controllability
when entering settings. Parameters 14 and 15 affect only the Up and Down buttons when the
user interface is in Running Mode.
Mode 1: Linear, Constant Rate
In linear mode, pressing and holding the Up or Down buttons will cause the display to
continuously change value in the requested direction until either the Display Minimum
or Display Maximum is reached. The displayed value will scroll at a constant rate which
is specified using parameter 15.
