Open a new plot window and plot the output current I(RL). Does the limiter do an accurate job? Check the output stage's currents by adding traces I(D1) and I(ROUT). Do they add up to I(RL)? Decrease RL. Does the output maintain its current limit?

(See Current Limiting) But, there's an easier way. By adding an amplifier, you can create an accurate current limiter that's independent of the diode voltage or final stage current. If your output current attempts to exceed the limit, the amplifier servos the output to your maximum current.

Hello, I am a student and I have to install a simple motion system (1 axis) for my current project. Before I start programming I would like to limit the current output to the DC motor from the drive to <1 amps to avoid any fast motion.
