Motion Coordinator Technical Reference Manual
Hardware Overview 2-17
Motion Coordinator Euro205(X)
Registration Inputs
The registration inputs are 24 volt non-isolated inputs referenced to 0v. The
Euro205(X) can be programmed to capture the position of an encoder axis in
hardware when a transition occurs on the registration input.
Differential Encoder Inputs
The encoder inputs on the Euro205 and Euro205X are designed to be directly con-
nected to 5 volt differential output encoders. On the Euro205X the encoder
ports are bi-directional so that when axes are set to stepper, the encoder port for
that axis becomes a Differential Stepper output.
Voltage Outputs
The Euro205(X) can generate 4 +/-10volt analog outputs which are primarily
designed for controlling servo-amplifiers. Euro205 requires a DAC chip (Burr-
Brown DAC4814AP) to be fitted in the socket provided, whereas the Euro205X has
the DAC chip soldered to the PCB. Note that for servo operation the necessary
feature enable codes must have been entered into the Euro205/Euro205X. To use
the voltage outputs the +/-12volt supplies must be present.
Using End of Travel Limit Sensors
Each axis of the Motion Coordinator system may have a 24v Input channel allo-
cated to it for the functions:
Switches used for the FORWARD/REVERSE/DATUM/FEEDHOLD inputs must be
NORMALLY CLOSED type.
Each of the functions is optional and may be left unused if not required. Each of
the 4 functions are available for each axis and can be assigned to any input chan-
nel in the range 0..31. An input can be assigned to more than one function if
desired.
The axis parameters:
FWD_IN
,
REV_IN
,
DATUM_IN
and
FH_IN
are used to assign input
channels to the functions. The axis parameters are set to -1 if the function is not
required.
FORWARD Limit
Forward end of travel limit
REVERSE Limit
Reverse end of travel limit
DATUM Input
Used in datuming sequence
FEEDHOLD Input
Used to suspend velocity profiled movements until the
input is released
