Configuring Micro Step Resolution
The micro step resolution configuration is required.
Use pin 4, 5, and 6 of the 6-pin DIP switch (Figure 12) of a
stepper drive module to configure the micro step resolution for the driven stepper motor. Refer to Table 3 for
available micro step resolution settings.

Connecting the DB25 Connector
Refer to “
Appendix A
” for detail specification for the MX3660 DB25 connector pin-out. The DB25 connector is
used to connect, directly / indirectly (e.g. via a circuit board), to a source of control signals (“controller”
hereafter) such as a motion controller, a PLC, an indexer, PC-based control system (e.g. Mach 3, Mach 4, EMC,
WinCNC, etc.).
The controller is the “Brain” of the whole motion control system for: (1) sending signals of step, direction, and
charge pump, to control the MX3660; (2) sending digital/analog signals for the controls of external devices,
which are connected at the MX3660 digital output connector; (3) accepting “Fault” output from the MX3660; (4)
take input signals sent from the external devices connected at the MX3660 digital input connector.
We will only depict the pin connections for step & direction, fault output, charge pump, and PWM. Refer to
Appendix A
for pin outs for other optional I/O’s
13.1.
Connecting the DB25 Step & Direction Pins
The step and direction pin connections are required.
Step signals are sent to the MX3660 via pin 2, 4, 6 of the
DB25 connector. Direction signals are sent to the MX3660 via pin 3, 5, 7. Refer to Figure 13.
Step and direction signal voltage should be 3.3-5 VDC and “Active High”. In the controller configuration, the step
width should be configured to a value at least 2.5 uS, and direction setup time needs to be at least 5 uS.
Otherwise, it could cause loss of steps, or no motion at all for the controlled stepper motors.
