We will select the sensorless vector method with feedback, to have a better torque
behavior, which is needed to perform the cycle consistently every time.
The motor heating calculation should be verified with the method of RMS power
during a complete cycle, or other method, shown later in this note.
The line reactor to be used is the GS-4100-LR, for 460 Volt, and the fuse kit
including the fuses is the GS-4100-FKIT. Please note that the fuse is sized for 600A,
600 Volt and is fast blow, to protect the drive and not the wire feeding the drive; In
general the branch circuit fusing is of a lower rating than that sized to protect the
AC drive.
Next we show the Durapulse wiring diagram for this specific application.

Note that it is necessary to determine the motor parameters for use with sensorless
vector control. This is done with the auto-tuning procedure.
The auto-tuning procedure should be done during the start up procedure. This is not
described here. Refer to the auto-tune procedure in Chapter 3 of the DURApulse
user manual.
