that they can operate as individual stand-alone units with their own programming language, power
supplies and separate sets of inputs and outputs. This means that the 10GM and 20GM can be used
with or without a PLC to control logic instructions and standard positioning operations.

Overview of control

Along with the capability to be used for independent control, the FX
FX -20GM (2 axes of control) can be used as special function blocks in conjunction with an FX
2N
FX PLC to transfer data back and forth via dedicated buffer memory addresses. These addresses
3U(C)
overlap with and replace the special M and special D registers in the 10GM and 20GM. One particular
advantage to using a PLC with the FX
positioning operations can be defined and saved for consecutive execution.
The FX
2N
mum output frequency of 200,000 pulses/second (200 kHz). This offers the same speed as the FX
high speed positioning adapters, except that the GM controllers use open collector type outputs
instead of differential line driver type.
Combined with standard positioning operations such as 1-speed and 2-speed positioning, the 10GM
and 20GM include an electrical zero return function to return the motor(s) to a specific user-defined
address without the use of a hardware DOG switch. This feature is unique since it is not available with
any of the other FX Series controllers.
