PowerFlex 4M & PowerFlex 4

[slcman 9]

What's the difference between PowerFlex 4 and powerflex 4M? Thanks

The 4M is cheaper and a little smaller if I remember right. Th4 4M measures the motor current differently than the 4. All parameters are renumbered. Make sure you use V2 firmware with 4M or you may have many false overload faults.

Also, the 4M has feed-through wiring (power in on top, motor leads on bottom) so it will more readily replace a motor starter or 160 series drive.
