High: On the up edge, the motor driver is configured for clock-in stepping or serial communication control based on the input state of the MODE0, MODE1, MODE2, and MODE3 pins.

Low: Motor driver is in standby and the motor is released from any of the control methods.

This pin is used to either place the motor driver in standby or initiate one of the control methods. (Click to enlarge)įor more details on the functions of the pins listed below, check out the datasheet for the TC78H670FTG. The input control connections on the ProDriver. ( *Occasionally, it wasn't apparent to us, until we looked closely at the latches.) This can be a head scratcher when the wires look like they are attached, but aren't properly connected.

This usually results in connections occasionally failing or secure wires slipping loose, moments after the board was working. Looking to the right end of the picture, below, you will notice that with the latch partially closed, it is relatively easy to accidentally insert a wire above the jaws.This should be fairly obvious however, we have found overconfidence to be an Achilles' heel, in this case. Make sure you are inserting the wire between the jaws.add a little solder) the wire leads and thicken the wires just enough to be clamped.

On some stepper motors, you may need to tin (i.e.

Just like screw terminals, there is a minimum and maximum wire thickness for the jaws to physically clamp onto wires.

If you look closely at the closed jaws or clamping mechanism, you will notice a small gap.

These should be fairly obvious, once you take a closer look at the jaws or clamping mechanism: When working with the latch terminals, there are two things to keep in mind. Details for the 3V3 and VM pins are described in the power section above. More details on these pins are laid out in the following sections below, excluding the power pins. The control and motor connections on the ProDriver.
