Wiring the Motor Thermostats
Some motor manufacturers provide the motors with integrated thermostat overload detection capability.
Typically, it is in one or two forms: a contact switch that is normally closed or a PTC. These sensors can
be wired into the Geo drive’s front panel at connector X1 and X2.
Motor 1 thermostat output is wired to pin 23 of X1,
In_Therm_Mot1 , and referenced to the GND
pin13 or 25. In addition, if dual axis drive is
ordered, Motor 2 thermostat output is wired to pin
23 of X2,
In_Therm_Mot2 , and referenced to the
GND pin 13 or 25.

Wiring the Motor Thermostats
MS{node},MI100 has special functions for Geo MACRO drives ( firmware 1.006 and above) to enable
the motor over-temperature function of the drive, default this function is disabled (firmware 1.006 and
above). If someone wants to enable the motor #1 over-temperature input to his Geo then he needs to set
MS{node},MI100= $4. For motor #2 over-temperature input to be enabled MS{node},MI100=$8 and if
the user wants both motor over-temperature inputs enable then MS{node},MI100=$C.
For earlier drives (firmware 1.005 and before) If the motor over-temperature protection is not required,
In_Therm_Mot1/2 should be connected to GND, pin 13 or 25. Otherwise, the drive status display will
show a warning error code
5
for motor #1 over -temperature, or an
A
for motor 2 over -temperature. If
both pins are not shorted to GND, display will show
5
(the first error gets triggered)
Wiring the Regen (Shunt) Resistor, J5
The Geo Drive family offers compatible regen resistors as optional equipment. The regen resistor is used
as a shunt regulator to dump excess power during demanding deceleration profiles. The GAR48 and
GAR78 resistors are designed to dump the excess bus energy very quickly.
The regen circuit is also known as a shunt regulator. Its purpose is to dump power fed back into the drive
from a motor acting as a generator. Excessive energy can be dumped via an external load resistor. The
Geo product series is designed for operation with external shunt resistors of 48
Ω
for the 10 and 15 amp
versions or 78
Ω
for the 1.5, 3, and 5 amp versions. These are available directly from Delta Tau as
GAR48 and GAR78, respectively. These resistors are provided with pre-terminated cables that plug into
connector J5.
Each resistor is the lowest ohm rating for its compatible drive and is limited for use to 200 watts RMS.
There are times the regen design might be analyzed to determine if an external Regen resistor is required
or what its ratings can be. The following data is provided for such purpose.
