POWER-UP/COMMISSIONING<br />
P21 -Motor Current Setting:<br />
Motor overload protection (Standard: OFF)<br />
This setting is set OFF at factory. This means that it is<br />
disabled and there is no motor overload protection. For<br />
an efficient motor protection, set as described in Section<br />
6.5.1 of this manual.<br />
P25 - Thermal classes of the overload protection:<br />
Selects the class of the overload protection suitable for<br />
the motor application (Factory Setting: 30)<br />
According to the thermal class curves in Section 6.5.2.<br />
Class 30 takes the longest time to activate the motor<br />
overload protection.<br />
To achieve a correct setting of this thermal class, proceed<br />
as follows:<br />
1. Verify the motor data sheet the locked rotor time<br />
and the starting current (I p<br />
/I n<br />
) for DOL tarting. Select<br />
a thermal class that in this condition trips in a time<br />
shorter (Section 6.5.2 - Figure 6.10) than the<br />
indicated motor data.<br />
2. Also check, if the selected thermal class, as<br />
described above, allows to start with reduced<br />
current. In this case, the actuation time, according<br />
to chart in Figure 6.10 - Item 6.5.2 - must be longer<br />
than the starting time of this motor with Soft-Starter.<br />

P28 -<br />
Motor service factor:<br />
Also applied for motor overload protection<br />
(Standard: 1.00), obtained from motor nameplate.<br />
Selection of the Operation Mode:<br />
It defines the connection type of the Soft-Starter to<br />
the motor (standard: OFF = standard connection).<br />
The Soft-Starter SSW-03 Plus can be connected in two<br />
ways to the motor: standard connection or connected<br />
within motor delta connection, as described in item<br />
6.4.1 of this manual.<br />
