Wow, I totally missed that they were driving 2 CIMs with 1 Victor. Yes, that is a problem. And No that is not legal.

There are only a handful of motors that let you have 1 Speed Controller and 2 motors, and the CIM is definitely not on that list.

See "Table 4-4: Legal Power Regulating Device Use" in R53.

Only the following motors can have 2 motors on one speed controllers:
  • Automotive Window/Door/Windshield
  • Wiper/Seat/Throttle Motors
  • AndyMark PG
  • Snow-Blower Motor
