CONNECTING THE STEP MOTOR
Phase 1&3 of the Step Motor is connected between pins 7 and 8 on connector P2. Phase
2&4 of the Step Motor is connected between pins 5 and 6 on connector P2.
Refer to Figure 1 for TYPICAL APPLICATION HOOK-UP
NOTE: The physical direction of the motor with respect to the direction input will
depend on the connection of the motor windings. To reverse the direction of the motor
with respect
to the direction input, switch the wires on Phase 1 & Phase
3
.
WARNING: Do not connect or disconnect motor wires while power is applied!
CONNECTING POWER
Pins 3 and 4 on connector P2 are used to connect the DC Power Supply to the
MDM40001. Wire size used to connect the power source to the driver should be at least
16 gauge. Heavier wire should be used for longer distances between the power supply
and the driver. The power supply requirements are as follows:
Switching Power Supplies and regulated linears with overcurrent protection are not
recommended because of their inability to handle surge currents. Adding a capacitor to
the output will alleviate this problem.
When multiple drivers are run from one power supply, each driver should have separate
power and ground wires that connect directly to the output capacitor of the power supply.
Refer to Figure 1 for TYPICAL APPLICATION HOOK-UP.
WARNING: When using an unregulated power supply, care should be taken to ensure
that the output voltage DOES NOT exceed the maximum driver input voltage because
of line voltage fluctuations. It is recommended that a input line filter be used on the
power supply to limit voltage spikes to the driver.
