    Easy to use. Runs cool. Read the manual, set the switches, wired them up and have not had to do anything else. 60+ running hours on 3 drivers.

    Works great, barely get warm running for an hour on 3A. Better than G540

    This product works great. Normally i would like to give it 5 star but i have a mobile application for what it is essential to plug and unplug the wires. Here comes the big problem. The two voltage wires and the four motor wires are connected to the same green six-screw plug. Whenever i need to unplug the six-screw plug from its terminal, i have to unscrew the two voltage wires to take the cables out from its case through different holes in the case. There are three solutions for this problem: 1. The fast one Take a cutter knife and cut out the wall of the 2-pin Enable terminal at the border of Dir + Pul. Use the six-screw plug for Ena+Dir+Pul and use the two-screw plug for power and the four-screw plug for the stepper motor. This way the power and motor cable can go out of its case in different holes. 2. The cheap one Dump the six-screw plug and get one more two-screw plug and one more four-screw plug. 3. The best one Get a driver what has the correct terminals to connect a six-screw plug for Ena+Dir+Pul, a four-screw plug for the motor and a two-screw plug for power. So every cable with plug can go out of different holes of its enclosing case.

    This driver is very the easy to setup and use. The documentation does not mention this, but to run a 200 steps per rev motor at full steps, all switches (5,6,7,8) must be on. However your motor will seems somewhat jerky, and running at 400 or 800 will be much smoother. Using an S-350-48 supply @ 47 volts I was able to drive a NEMA 24 motor up to 1350.4 RPMs. The motor must be accelerated to this speed or a stall will occur. The driver did not show any signs of over heating, or stress. Per documented specs, the pulse on duration was 2.5 micro seconds but it will operate at 0. (though not reliably). I was able to drive my NEMA 24 motor up to 172.4 kHz. I have no doubt the driver will run at the advertised 200kHz, but the motor must be able to respond to a frequency so high. For the money, this is a fantastic driver. Actually, even a more expensive driver probably wont perform much better.
