Problem / unsteady Reliance MaxPak DC drive
We have a 1972 Reliance MaxPak 40HP DC drive which has developed an erratic behavior, the motor's speed varies without reason. When a constant speed is set, it will work steady for some time, slow down for 0-5 minutes, ramp up in speed past the set speed for a few seconds and then settle back...- LucCx
