2.13 Commissioning SIMOTICS 1FW6 built-in torque motors
Checking the phase sequence, EMF phase U - EMF phase V - EMF phase W
For a positive direction of rotation of the drive, the phase sequence must be EMF phase U -
EMF phase V - EMF phase W
Checking the phase position, EMF phase U - EMF phase V - EMF phase W
In the following diagram, the phase shift of the individual voltages with respect to each other
is 120°.
