Given a 24V 1A motor with no actual load connected (just a piece of orange tape so we can see the shaft moving). How much current will the motor use if I configure the driver board for 2A maximum hold current?
This is the scenario:
We have a breadboard that is configured for 2 motors at 24V 2A. However, we only have 1 motor and axis configured for now. So until we get the second motor, I asked for just any motor to be connected to the second channel so that I can see that the software is working. The project EE found a 1A motor and connected that. The EE then warned me to reduce the maximum hold current to 1A. I was told that the driver board would "push" 2A of current to the motor.
This is where I get confused:
I don't understand how the motor could draw 2A when there is no load, even if there was no current limit at all.
I thought that the "maximum hold current" was the current limit. Not that the board would push 2A to the motor. At 24V, supposing that the motor was drawing say 200mA just sitting there idle, wouldn't the driver board have to supply 24V x 2000mA/200mA = 240V to get 2A of current into the motor?
