MC206 - Stepper Outputs / Encoder Inputs
The MC206 controller is designed to support any combination of servo and step-
per motors on the standard controller hardware. Each of the first four axes (0-3)
can be enabled as either servo or stepper according to the users requirements.
The function of the 9-pin ‘D’ connectors will be dependant on the specific axis
configuration which has been defined. If the axis is setup as a servo, the connec-
tor will provide the encoder input. If the axis is configured as a stepper, the con-
nector provides differential outputs for step/direction and boost/enable signals.
The encoder port also provides a current-limited 5v output capable of powering
most encoders. This simplifies wiring and eliminates external power supplies.
Once the axes have been enabled, using the
FEATURE_ENABLE
function, the con-
troller will enable the appropriate hardware for each axis and the connector will
function as below.
