I saw this in a post a new member wrote in the Monarch Lathe section. I was thinking this would be the forum or Rigging forum.

First i want to thank everybody for their knowledge sharing, but still i am not able to solve my problem.
"I have a overhead crane it has problem with its braking resistor for long travel.. But when I connect the braking resistor to the drive it starts heating to very high temperature Even the crane is not in motion, I tried to adjust the parameters but all in vain.. Could you help me solve my problem.. I am using sk commander inverter EMCSKC3400400. Q
