Interfacing Outputs
The MDrive Motion Control Outputs may be configured as either general purpose or set to one of two dedicated functions, Fault or
Moving. These outputs will sink up to 700 mA max and may be connected to +5 to +24VDC. Note that a current limiting resistor may
be required to limt the current to 700 mA.
As with the inputs the MDrive Motion Control Outputs may be used singularly or collectively as a group.

Interfacing Outputs as a Group Example
To write to the outputs as a group the OT instruction is
used. This will give you a binary output of 0000 to 1111
from a decimal entry of 0-15. Output 1 will be the Least
Significant Bit (LSB), Output 4 will be the Most Significant
Bit (MSB).
See Table 2.4 for Truth Table.
