Chapter 5: Keypad Menu Items and Parameters
5.1.5 – Data Entry Mode
The Data Entry Mode is entered as soon as the bottom level of the menu structure for that
particular menu branch is reached, i.e., a menu item or parameter name is displayed in the top
line of the keypad display, and the associated value is displayed in the bottom line of the display.
Not all parameter values can be changed by the user, as some are read-only.
A user can tell whether the menu item or parameter is writeable, as there will be a flashing cursor
present on the bottom line of the display if writing is permitted. Writeable values may be changed
by using the Up and Down keys (for a numerical value), or by pressing ENTER (for a change in a
logic value). In the first case (a numerical value), the ENTER key must be pressed to confirm the
changed value. The user interface display will flash once to confirm the change.
5.1.6 – Changing Parameter Values
All parameters can be read by the user, and some parameters can also be written to by the user.
The full list of parameters and their values can be found in the Parameter Menu and subsequent
sub-menus. The most commonly read and written to parameters can also be found under the
other Level 1 (see Figure 5.2.1) menus such as ‘Basic’ and ‘Applications’. A simple example of
how to view and change a parameter value is given in Appendix A.1.3.
5.1.7 – Soft Starter Data Types
There are basically four types of data held in parameters: Analog, Multiple, Percentile, and Bit
data. Their definitions are given below:
Analog Data
One of a range of values between two extremes (usually 0–255, 0–50 or 0–10) that represent units
such as Volts, Amps, seconds, etc. For example: ‘Start Time’ (‘Stopped & ready’ --> ‘Basic’ -->
‘Start Time’) would be set at 5 seconds by default, but can be set to a maximum of 255 seconds.
Multiple Data
A multiple of an absolute quantity. For example: the running current displayed by the unit is a
multiple of the value of the unit’s ‘Rated Current’ (e.g. 1.0 x ‘Rated Current’ to 8.0 x ‘Rated
Current’). Note that the unit’s ‘Rated Current’ normally approximates the motor or load Full Load
Current.
Percentile Data
Percentage value of an absolute quantity, ranging from 0–100%. For example: the ‘Kick Pedestal’
(‘Stopped & ready’ --> ‘Advanced’ --> ‘Kick Pedestal’) is the percentage of supply voltage applied
to the unit during an optional start-up kick.
Bit Data
This represents the selection or non-selection, turning ‘On’ or turning ‘Off’ of whichever bit
parameter is in question.
To keep Menu Item and Parameter setting changes, they must be permanently saved using the ‘Permanent
Store’ menu. (See section A.1.5 for more information.)
