Commissioning the Drive

Key Steps to Commission a
PowerFlex 7000 Drive

As a guide for a commissioning engineer, the major steps involved in the
commissioning of medium voltage PowerFlex 7000 drives are outlined below in a
sequential order. For detailed instructions, always refer to the relevant PowerFlex
7000 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 Lockout Tagout procedures 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.
