5.4 – Menu Settings and Parameter Descriptions
This section gives a description of the individual menus and the functions that their parameters
perform.
• Menu Settings and Parameters are presented in the same groups and sequence as they appear
in the Keypad Menu Structure.
5.4.0 – Restoring Defaults
There are two methods of restoring the SR44 parameters and settings to their default values:
1) Through the ‘Applications’ menu; choose ‘Default (keypad)’ or ‘Default Auto’.
2) Through the ‘Permanent Store’ menu; choose ‘Default Param’.
Refer to the applicable menu descriptions for further details.
5.4.1 – Example of Menu Settings and Parameters Descriptions
* Scaling:
• Scaling applies ONLY when using SERIAL COMMUNICATION to read and write parameters.
• When READING from parameters, MULTIPLY the serial comm value by the scaling factor.
• When WRITING to parameters, DIVIDE your desired value by the scaling factor (multiply by the
inverse of the scaling factor).
• Refer to “Chapter 6: Serial Communications” for scaling example.
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.)
We highly recommend that you configure the SR44 by first selecting and setting an application from the
“Applications” menu that is similar to your application. If necessary, you can then ‘fine-tune’ your
configuration by changing the settings of other parameters and menu items.
Start Time
Range: 1 to 255 seconds Default: 5s Scaling: 1 Type: R/W
‘Soft Start Time’ sets the soft-start time period over which the unit ramps voltage to the motor.
• Start times are normally in the 5–30s range.
• Long ramp times over 1minute are for special applications only.
• The start (without current limit) is purely a voltage ramp.
• Lightly loaded motors will normally reach full speed before the end of a long ramp.
