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.   
I1013 was specially created ( firmware 1.17C and above) for Geo PMAC drives to enable the motor over-
temperature function of the drive, default this function is disabled. If someone wants to enable the motor 
#1 temperature input switch to his Geo then he needs to set I1013=1. For motor #2 over-temperature input 
to be enabled I1013=2 and if the user wants both motor over-temperature inputs enable then I1013=3. 
For earlier drives (firmware 1.17A and 1.17B) If the motor over-temperature protection is not required, 
In_Therm_Mot1/2 should be connected to GND, pin 13 or 25 of X1/X2 respectively.  Otherwise, the 
drive status display will show a warning error code 5 for motor #1 over -temperature, or an for motor 
#2 over-temperature. If both pins are not shorted to GND, display will show (the first error that gets 
triggered). 
On the right side there is an example on how the 
user could wire to the thermostats.

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.
