Chapter 4 Commissioning the Drive
Capturing Data
The last step should be to upload “black box” data from the DPM. This captures
all parameters (regardless of the user access level), the various firmware revisions,
the exploded fault masks, the PLC links, and the Analog configuration.
Always upload the seven files from the black box. The “Variables.csv” file should
be taken with the drive running with MV.
All of this information is necessary as reference to address future customer issues.
Guidelines For Data Capture
This section provides some guidelines for capturing required commissioning data
and setting up oscilloscope to capture the waveforms. 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”.
IMPORTANT Once you complete the final commissioning procedures and the drive is
running, CAPTURE ALL DRIVE DATA for future reference.
