Why PowerFlex Drives Fail After a Plant Shutdown
When a plant experiences a planned shutdown, turnaround, holiday outage, or utility maintenance window, one or more PowerFlex drives fail within minutes or hours of re-energization. This is a distinct, recurrent pattern that maintenance engineers in the heavy industry can quickly identify. After years of trouble-free operation, the drive suddenly malfunctions, trips a breaker, or, in the worst situations, literally destroys an IGBT module. It is a foreseeable result of power electronics deteriorating when idle, contaminants and moisture building up when a drive isn’t producing heat, and a plant’s restart cycle interacting with both. The difference between considering every shutdown-related failure as a mystery and creating a restart strategy that stops it is an understanding of these mechanics. The internal parts of a PowerFlex drive are designed to operate continuously or almost continuously. Long-term proper operation of the DC bus electrolytic capacitors, IGBT gate driver boards...

The Hidden Cost of Running Oversized VFDs
When designing or making electrical installations, the first thoughts often turn to how much safety margin to build into the electrical design so it will withstand a certain amount of overcurrent during an emergency or surge. But when we install a VFD, the idea of putting an oversized one to build in a safety margin actually backfires. An oversized drive does not provide any safety margin — it decreases energy efficiency and motor protection while increasing harmonic distortion and costs. A good rule of thumb is that any drive should not be larger than twice the rating of the connected motor. Drive manufacturers go further and specify that the motor must carry a rating above 50% of the drive. Combining a 150 kW drive with an 11 kW motor gives only a 7.3% ratio. The issue comes from the large difference between the motor’s operating current and the VFD’s rated current range. A VFD measures the output current and uses it for motor control, torque estimation, and electronic overload...

How PowerFlex Drives Handle Regenerative Loads
DC Drive regen technology isn’t anything new. In fact, they’ve been around since the late 1800s and have been evolving to make industrial systems more efficient. In Rockwell Automation’s PowerFlex lineup, regeneration can be handled through several different architectures, including active front end systems, common-bus systems, regenerative DC drives, and medium-voltage regenerative drives. Today, this lineup extends its regenerative technology to the PowerFlex 755TR, PowerFlex 755TM, PowerFlex 755TL, PowerFlex 7000, PowerFlex DC , and the PowerFlex 700AFE. To understand how a PowerFlex drive handles regenerative loads, it’s best to start at the drive’s front end. In a traditional AC drive with a passive diode front end, incoming AC power is rectified into DC power before the drive inverts it back into controlled AC power for the motor. Under normal motoring operation, that power path is one-directional from the line, through the drive, and out to the motor. When the motor...
