2.5. Connecting Stepper Motor
MK-200 supports standard stepper motor amplifiers operate with PWM
and Direction mode. When stepper operation is selected, MK-200 does
not support encoder inputs (CHA and CHB).
Figure 9 shows the typical connection of stepper motor to the MK-200.
Note that the Stepper Select, Stepper A, is connected to ground.

2.6. Connecting the Limits
There are two directional limits per axis, which can be used to prevent
collision due to over travelling. Leave these limits unconnected (inactive) if
we do not wish to use them.
Both Forward and Reverse limits are active low.
If the Forward Limit (FL) is active, it inhibits the forward motion
immediately. If the Reverse Limit (RL) is active, it inhibits the reverse
motion immediately. After a limit has been activated, further motion in the
direction of the limit will not be possible until the state of the limit returns
back to inactive state. This usually involves physically moving the
