5.5 – Definitions for Chapter 5
Dwell
This is the period between ‘Top of Ramp’ and ‘Run’, which is designed to give unstable loads a
chance to settle down, and to ensure that they are up to speed.
Index Rating
The Index Rating defines the duty of the starter.
Jog
Small movements of a three-phase induction motor, usually used when commissioning the motor
or load.
Keypad
The keypad is the internally mounted user interface. The user can start/stop, program, and query
the unit’s status through this interface. Fitting of the keypad precludes fitting of a remote keypad.
Keypad, Remote
The remote keypad is the externally mounted user interface. The user can start/stop, program, and
query the unit’s status through this interface. Fitting of the remote keypad precludes fitting of the
internal keypad.
Kick Start
This is an optional extra ‘kick’ of voltage to start ‘sticky’ loads.
Load Current
The current drawn by the application or load.
Optimize
This is an optional energy saving feature. The SR44 will reduce voltage to a lightly loaded motor.
(Refer to the “Applications” chapter of this user manual for a detailed explanation.)
Overload
An Overload is a sustained over-current, with a duration of seconds or minutes rather than cycles,
that might or might not end in a trip. Changes in the load characteristics might cause an overload.
(An Overload generally draws less current than a Shearpin.)
Parameter
A parameter is a menu item that directly relates to an internal parameter of the Soft Starter.
Rated Current
This is the nominal current (in Amps) at which the unit has been designed to run.
Shearpin
Shearpin is also an over-current, but of a much shorter duration (cycles rather than seconds), and is
generally a higher current than an Overload.
Stall
The point at which the load placed on a motor threatens to stop a motor’s rotational movement.
