Stepper Motor Connection Hints
BESSRC uses the standard stepper motor connectors used at the APS. These are available
from at least two manufacturers - EDAC & ELCO. Part numbers and pictures for the EDAC connectors
are shown in the table below.

NOTES
|
|
|
An adapter cable to connect the ACS 5-phase
motor driver to the DB-25 connector for the 5-phase
motors on the Huber Diffractometers
|
Connect to microstep drivers only!!!
If the direction is wrong, either swap
the connections to one of the motor phases
(e.g. A & E) or swap the limit switches over
(e.g. W <> X & T <> U)
|
|
The photo shows a typical connector used with a Superior Electric
Slo-Syn six-wire motor. Notice that wire links have been inserted for
the limit switches (between T&W and U&X) - all the BESSRC
motor drivers are set up to expect the limit switches to be normally
closed.
Unipolar vs Bipolar Drives.
Be aware that the two kinds of ACS Step Pak drives that we use are
not fully interchangeable with each other. The microstepping drivers
are bipolar and do not drive pins B,D,F & J at all. If you wire
up a six-wire or eight-wire motor according to the chart above then
it should work with both the microstepper and the non-microstep
drivers. Four lead motors will ONLY work with the microstep driver.
If you wired a six-wire motor according to an earlier version of this
chart - which had the white wire going to pin J rather than pin H -
then the motor will NOT work with the microstep drivers. When using
an ACS microstep driver in this way you will only drive half of the
available coils in the motor. If you need more torque you should make
a small adapter cable to use all of the motor coils. The connections
should be as follows:

Huber Slit Adapter for moving 2 slit motors with constant slit
opening
This adapter may be used to drive two huber slit motors from a
single driver. The two slits move in the same direction, keeping a
constant slit opening. The two motors rotate in opposite directions
to acheive this.
