Commissioning the Drive
Key Steps to Commission a
PF7000 Drive As a guide for a commissioning engineer, the major steps involved in the
commissioning of medium voltage PF7000 drives are outlined below in a
sequential order. For detailed instructions, always refer to the relevant PowerFlex
7000 drive’s user manual.
• Review the drawings and identify all sources of energy that apply to the
drive system and get better understanding of the application to which the
drive system is applied.
• Follow safety procedures and apply LOTO before working on the
equipment.
• Complete all power off checks and note down motor and drive nameplate
data.
• Apply control power and perform power on checks.
• Perform gating test.
• Program the drive after verifying the information on EDs and DDs against
the equipment nameplate data.
• Ensure the drive hardware and parameters are correct, such as HECS/CT
ratio and burden resistors installed in the drive are accurately programmed
in drive parameter settings
• Perform system test and verify operation of the drive and the associated
controls.
• Remove any jumpers used during system test.
• Inspect the drive line-up and ensure that no tools are left inside the
cabinets before closing them.
• Apply medium voltage and complete incoming line phasing checks and
take harmonic measurements.
• Perform DC test. Ensure that the Diagnostic Trend is setup and ready
before attempting the DC test.
• Perform Stationary Autotune tests (first 2 autotune tests).
• Bump the motor for rotation check.
• Complete Rotating Autotune tests (last autotune test) .
• Save the parameters in NVRAM and also transfer them from drive to
memory and also print the drive setup to your laptop.
• Start the drive in normal operation, print variables and capture waveforms.
• Complete commissioning documentation.
