I am new to the MM420 and have noticed that while the drive is powered up (480VAC three phase) but the motor being controlled is OFF, the cooling fan never kicks on to keep the drive cool. Once the motor kicks on, the fan will turn on and cool the drive properly.

While setting up the drives via the BOP, I noticed the drive gets quite hot to the touch on the right side after 10-15 minutes of being powered up with the motor off. Is this typical of these drives? All three drives being used for this project exhibit the same issue and the heat seems excessive to me. Is this amount of heat normal?

Thanks in advance.
