II. DRIVE
1. Make sure the motor to be used is compatible with the drive.
Refer to the Section 3.3 for a list of compatible motors.
2. Use the motor connection diagrams shown in section 2.2 for
connection 4-, 6- or 8-lead motors. When using a 6-lead
motor, be sure to insulate and isolate the unused motor leads
to prevent inadvertent shorts to ground or to each other.
3. Install a resistor of appropriate value between the REDUCE
CURRENT- pin and the LOGIC COMMON pin. Refer to the
speed versus torque data in section 4 and the resistor ver-
sus current table in Section 3.7. If you desire to run the
REDUCE CURRENT- manually, refer to the circuit shown in
Figure 3.
4. Caution: The Drive Module case is connected to the Vom
and LOGIC COMMON pins internally. Do not connect your
power supply to ground at any other location.
5. Caution: Erratic operation may occur at speeds less than
350 steps per second due to motor resonance. Avoid this
speed range if a problem exists.
