Motor Connection
The EMX4i can be connected to the motor in-line or inside delta (also called
three-wire and six-wire connection). When connecting in inside delta, enter the
motor full load current (FLC) for parameter 1B. The EMX4i will automatically detect
whether the motor is connected in-line or inside delta and will calculate the correct
inside delta current level.
NOTE
If the starter is not correctly detecting the motor connection, use parameter
