1.2.4 Explanation of concepts
The setting of current I
e
is the setting for the rated operational current (main cur-
rent) of the motor.
U
e
= Rated operational voltage on the motor’s operational current (three phase
main voltage feeding the motor).
U
s
= Rated control supply voltage, feeding the electronics in the softstarter.
U
c
= Rated control voltage, used for controlling the softstarter.
