2-6 Hardware Overview
Motion Coordinator MC202
Trio Motion Technology
either as an input or an output. They are numbered from 8 to 11 for greater com-
patibility with other Trio Motion Coordinators. The inputs channels 0 to 3 are not
bi-directional. Inputs 0 and input 1 can be used as registration inputs for axes 0
and 1 for use with the
REGIST command.
Bottom 14 Way Connector:
This is a 14 way 3.81 pitch connector. The connector provides for 2 axes of 5v dif-
ferential encoder inputs, 2 axes of step and direction encoder inputs and a 5 volt
output for powering external encoder only.
Axis 0 Encoder Inputs:
6 pins are used to provide dedicated encoder inputs for Axis 0. If axis 0 is used as
a stepper axis these connections are not required. The inputs are 5 volt differen-
tial encoder inputs. The inputs must be connected to the encoder via a screened
cable and the screen connected to the panel ground.
Encoder Power Supply:
2 pins provide a low power output at 5v (150mA maximum). This supply is pro-
vided for driving one or two encoders (if current consumption permits). The
power supplies should be included within the encoder screened cable. Do not use
the 0V as a screen ground point.
Stepper Outputs / Axis 1 Encoder Inputs:
6 pins are used to provide encoder inputs for Axis 1. Alternatively 4 of the pins
can be used as step and direction open-collector outputs for axes 0 and 1. The
inputs are 5 volt differential encoder inputs. Whatever the use of the pins they
must be connected to the stepper drive or encoder using screened cable and the
screen connected to the panel ground.
