GECKO MOTOR WIRING
--------------------
Excerpts from Gecko 201 manual and other sources for actual wire colors.
Motors rated phase current: 0.3 AMP - 7 AMP. Power supply voltage should
be between 4x and 20x the motor rated voltage. The current set resistor
may be 1/4W, 5%. Current set resistor goes across T11 and T12. Values:

|---------------------------------------------------------------------|
| Terminal# | Description |
|-----------|---------------------------------------------------------|
| T1 | Supply Ground |
| T2 | Supply Power (+) (+18VDC to +80VDC) |
| T3 | Phase A |
| T4 | Phase B |
| T5 | Phase C |
| T6 | Phase D |
| T7 | Disable windings (when connected to ground T12) |
| T8 | Direction (ground-going signal relative to +5V common) |
| T9 | Step (ground-going signal relative to +5V common) |
| T10 | +5V Common |
| T11 | Current set resistor |
| T12 | Current set resistor (ground) |
|___________|_________________________________________________________|
Use heat sinks for current settings above 3 amps.
Drive should be heatsinked to a piece of aluminum, preferably with
fins and a fan to increase heat dissipation and surface area.
GECKO OPTION JUMPERS

GECKO COMPUTER CONNECTIONS
--------------------------
On the Kuper cards and A800 boards, connect STEPS to T9, DIRECTION to T8,
and +5v from card (pin 20) to T10, e.g.
Kuper RTMC/A800 Pin Gecko Drive Terminals

GECKO MOTOR CONNECTIONS
-----------------------
In the following table, T3, T4, T5 and T6 refer to the numbered
terminals on the drive. Colors indicate the wire colors that come
off the motor. NOTE: These are derived from Centent docs, which
/should/ be compatible. From what I could find, Gecko doesn't
provide diagrams showing wire colors, but they seem to be
terminal compatible with the Centent drives (which does).
