Technical Description
FieldBusPlug / Issue: 03.2012
Motor Wiring
Have a look at the wiring of the motor to set the correct nominal current I
e
for perfect motor protection.
Example:
For inner delta wiring the parameter Current Factor can be changed to 1.73 to display the actual currents
on the Control Panel and in the control system. The delta 3 circuitry is normally used for larger motors to
reduce the current transformer size.
