CCBU40 COMPACT CONTROLLER BOARD - PRODUCT AND WARRANTY INFORMATION
Version 1.21
Important note: Since no flow control is implemented in the serial configuration, the flow control is
performed with the acknowledgement characters. It is thus recommended to wait for acknowledgement
‘X’ before sending the next command. In case a new command is issued while acknowledgment of the
previous command has not been received, an overflow of the serial buffer could occur, leading to a
communication error, and the command would be ignored
LIST OF COMMANDS

Description of the command
Parameter range
Examples
‘V’
This command allows selecting the axis on which
the next digital commands will be applied.
Once an axis is selected, all following
commands apply to this same axis, until
another selection is made.
Upon power-up, the axis X is selected by default.
1:
The
axis
X
is
addressed
2:
The
axis
Y
is
addressed
‘V1E’ selects the X axis for the
next commands.
‘B’
This command allows selecting open-loop or
closed-loop operation.
0: Open-loop operation
of the selected axis
1: Closed-loop operation
of the selected axis
‘B1E’
selects
closed-loop
operation.
‘T’
This command allows between digital command
or analog command.
This configuration is ignored if configuration
switch N°2 is mounted. In that case, analog
commands are used on both axis.
0:
Analog
command
‘AIX/Y’ is used for the
selected axis
1: Digital command is
used for the selected axis
‘T1E’ selected the digital
command.
‘Z’
This command sets the digital order value for the
selected axis.
This command should be used for sending
commands in real-time (faster execution time).
The digital order will be used only if the
corresponding axis is setup for working with
digital commands.
[-10V ; +10V]
‘Z2.435V’ sets a digital order of
2.435V.
‘W’
This command sets the digital order value for the
selected axis and saves it to the memory (longer
execution time).
The digital order will be used only if the
corresponding axis is setup for working with
digital commands.
[-10V ; +10V]
‘W-5.335E’ sets a digital order
of -5.335V.
‘M’
This command sets the upper limit for the output
to the power amplifier, for the selected axis. If the
controller output is larger, it will be saturated to
this value.
[-1V ; +7.5V]
‘M4.678E’ sets the upper limit
of the output at 4.678V.
