OEM650/OEM650X • INTRODUCTION
1 Introduction
Chapter Objective
The information in this chapter will enable you to:
❐ Understand the product’s basic functions and features
OEM650 Description
The OEM650 Drive is intended to be a high-performance basic
engine around which the original equipment manufacturer (OEM)
designs his motion control system. Its single-power DC input makes
it a convenient and cost effective motion control module. The drive
offers a basic set of customer configurable features. These features
are designed to meet the needs of most customers. The OEM650 is
optimized to operate size 23 and 34 motors.
The OEM650 is a bipolar, recirculating, microstepping drive designed
to drive two-phase permanent magnet hybrid step motors. The drive
uses a custom ASIC, surface mount, and MOSFET technologies to
give high performance in a small package while providing short
circuit protection. The OEM650 is compatible with all Compumotor
indexers.
The mechanical design is a fully enclosed product that uses a
heatplate technique to provide a heat dissipation path. The user
must attach the OEM650 module to a suitable mounting surface.
OEM650X Description
The OEM650X Drive/Indexer is the same drive product as the
OEM650, but it includes an indexer (position controller). The
OEM650X is the same size as the OEM650 and it incorporates the
same design technologies (bipolar, recirculating, microstepping drive
designed to drive two-phase permanent magnet hybrid step motors,
custom ASIC, surface mount, and MOSFET technologies).
The indexer utilizes commands from Compumotor’s popular and
easy-to-use X Series Language. The indexer also provides additional
I/O control and communication
OEM350/350X Description
The OEM350/OEM350X is a low power version of the OEM650 drive.
It is designed for use with step motors that have lower current
ratings and higher inductance (10 mH to 80 mH) than Compumotor
1
INTRODUCTION • OEM650/OEM650X
step motors. Operation of the OEM350/OEM350X is identical to that
of the OEM650/OEM650X. For clarity, instructions in this manual
use only the name OEM650/OEM650X. Except where differences are
specifically noted (resistor values for motor current settings, for
example), OEM650 instructions also apply to the OEM350, and
OEM650X instructions also apply to the OEM350X.
Features
The OEM650 requires an external power supply. It uses 24VDC 75VDC for its power input. Compumotor’s motors are two-phase
hybrid motors (permanent magnet type). Four, six, or eight leaded
motors may be used with the internal phases connected for either
parallel or series operation. The motor’s inductance cannot drop
below 0.5 mH. For best performance, motor inductance should be
between 1 mH and 10 mH, but motors with inductance ratings as low
as 0.5 mH may be used. Use the OEM350/OEM350X with motors
whose inductance is in the 10 mH to 80 mH range. The OEM650/

3. Slide the drive cover back on.
4. Attach the motor (to A+, A-, B+, B-). Do not connect the motor to
the load at this time (refer to Figure 2-2 for 23 size motors or
Figure 2-3 for 34 size motors). OEM size 23 motors may be wired
in a series or parallel configuration. If you are using a 75VDC
power supply (OEM300) with the drive or drive indexer, Compumotor recommends that you use a series configuration, however; a
parallel configuration should be used when the power supply is
24VDC - 48VDC. Parallel configurations will cause the drive to
dissipate slightly more heat than a serial configuration. This
increase in drive temperature will not affect the unit's performance,
but it may adversely affect heat-sensitive devices that are stored
within the same enclosure.

OEM size 34 motors are internally wired in parallel. A 75VDC
power supply (OEM300) must be used to achieve maximum performance; however, lower voltage power supplies may be used (less
than 75VDC but must be greater than 24VDC). The lower voltage
power supply will not adversely affect the system's low-speed
performance, but it will not yield the optimum high-speed performance achieved by using the 75VDC power supply.

Table 2-7. OEM Drive Motor Current (Compumotor Motors)
If you use a non-Compumotor motor, carefully follow the motor
manufacturer's instructions regarding motor wiring and the
proper operating current. Compumotor recommends a motor
inductance of 2 mH measured in series or parallel (0.5 mH - 10
mH is acceptable). Table 2-8 shows resistor values that you must
use to properly set motor current when using the OEM650/
OEM650X with a non-Compumotor motor. When the motor
current range jumper (jumper 1—see Figure 2-1) is installed, the
drive can generate 2.5 to 7.5 amps. When jumper 1 is removed,
the drive can generate 0.83 to 2.5 amps. If you use the OEM350/OEM350X, use Table 2-9 for resistor and current values to use
with high-inductance (10 mH to 80 mH), low current motors.

1. Complete steps 1- 6 from the OEM650 Quick Test, but do not
remove jumper #11 (Auto Test Function).
2. To connect a Compumotor indexer to the OEM650’s 25-pin D
connector refer to Figure 2-6.
To connect a non-Compumotor indexer to the OEM650's 25-pin
D connector, refer to Figure 2-7.
3. Apply power. The OEM’s green power LED should be on. If the
red FAULT LED is on, consult Chapter 5, Troubleshooting.
This test assumes that your indexer’s motor resolution is set to
25,000 steps/rev. This is the default motor resolution setting
for the OEM650.
4. Using the indexer, send step pulses to the drive that will rotate the
motor one CW revolution (25,000 step pulses) at 1 rps (25,000
steps per second).
5. Using the indexer, send step pulses to the drive that will rotate the
motor one CCW revolution at 1 rps. The drive's default direction
is CCW (i.e., if the the direction input is not activated, the motor
will rotate CCW—if the direction input is activated, the motor will
rotate CW). If the motor does not rotate in the desired direction,
reverse the direction sense for your system by reversing the leads
going to the A+ and A- terminals.
WARNING
Never connect or disconnect any component to or from the drive with power
applied. System damage or personal injury may occur.
