We have a vertical Axis which was overheating while not moving.
After further investigation I found that when the axis moves upward to a position then stops at that position, the kinetix 5500 drive still outputs around 4amps to the Servo motor while at standstill indefinitely (slightly less then it was using to actually drive the axis upwards to the position)
causing the servo to overheat over time.
but if I do the same thing as above but move the axis downward when it reaches its position the current is very low.
I have implemented a band aid fix where whenever I drive upward to a position I then drive downward 10mm after reaching the top position and this clears the high standstill current.
Is there a parameter or something I'm missing here... this behavior seems very odd to me..
TIA
