Commissioning Chapter 4
Capturing Data When all of the final commissioning procedures are completed and the drive is
running, it is VERY IMPORTANT TO CAPTURE ALL THE DRIVE DATA
for future reference.
The last step should be to PRINT DRIVE SETUP. This will print all the
parameters (regardless of the user access level), the various firmware revisions, the
exploded fault masks, the PLC links, and the Analog configuration.
All of this information is required to address future customer issues.
This section provides some guidelines for capturing required commissioning data and
setting up oscilloscope to capture the waveforms. For detailed instructions, always
refer to PowerFlex 7000 user manual. Some sample waveforms have been included
for reference purpose.
Drive Input Voltage Phasing
Checks After applying medium voltage to the drive, perform an input voltage phasing
check.
Summary:
• Drive input contactor should be closed. If the drive input contactor
configuration is set to NOT RUNNING, you will have to temporarily
change it to ALL FAULTS.
• Ensure that the drive is not running when capturing these waveforms.
• Capture the three line voltage waveforms at ACB test points
•
Master winding: V2uv, V2vw & V2wu
• In the case of 18 Pulse drive, verify 20 deg phase shift between the Master
and two Slave windings for each phase voltage and capture the waveforms
at ACB test points:
•
Slave 1 winding: V3uv, V3vw, V3wu
• Slave 2 winding: V4uv, V4vw, V4wu
• Label the waveforms as “V2uv”, “V2vw” and “V2wu”, etc.
• Save the worksheet as “Input Phasing”.
