7.2 Additional parameter information
Due to its user-friendliness and simplicity of use, the most parameters of the VACON
®
100 X Solar
Pump Application only require a basic description which is given in the parameter tables in chapter
7.1.
In this chapter, you will find additional information on certain most advanced parameters of the
VACON
®
100 X Solar Pump Application. Should you not find the information you need contact your
distributor.
7.2.1 Motor Control
P3.1.1.2 M
OTOR NOM FREQ
NOTE! When this parameter is changed, parameters P3.1.4.2 and P3.1.4.3 will be automatically ini-
tialized depending on the selected motor type. See Table 130.
P3.1.2.1 C
ONTROL MODE
P3.1.2.2 MOTOR TYPE
This parameter defines the used motor type.
When this parameter is changed, parameters P3.1.4.2 and P3.1.4.3 will be automatically initialized
according to the selected motor type.
