I have a standalone app with a freq drive. I just need to control the motor speed by allowing an operator to input the speed (in scaled units, not motor freq) through a very simple, inexpensive HMI.
I am finding it difficult to find a freq drive/hmi combo that actually does this. I have talked with AB, SqD, and others and all tell me they only allow input in motor frequency, unless I use a plc or other comm device in between that makes the hardware too expensive. I need a low cost solution. It seems too simple for no one to offer what I am looking for. Any advice?
