Commissioning the Drive Chapter 4
Monitor the Line Voltage pu (P#135), and increase the tap setting on the drive
feed if the measured value is less than 1.03 pu. It is desirable to have Line Voltage
pu read in the 1.03 to 1.07 pu range. Alpha Rectifier (P#327) should be greater
than 15
o
while running at rated speed and load, indicating how far forward the
rectifier is phased. The input voltage should be increased by tapping up the
transformer.
Fill in the following table with data from the various load points. If possible,
capture the running parameters with the printer, DriveTools, or Hyperterminal as
a substitute for recording the data in the table below. This should be forwarded
with all commissioning data back to Product Support for future reference.
