CCBU40 COMPACT CONTROLLER BOARD - PRODUCT AND WARRANTY INFORMATION Version 1.21
This command requests the sensor feedback.
This command operates in the same manner
whatever the axis selected.
The electronic answers with 4 data bytes followed
by acknowledgement character. The 4 data bytes
represent a signed integer value. Based on this
value, the status of the system is as follows:
Sensor feedback [V] = Value / 3276.8
1: Sensor feedback for
axis X is requested.
2: Sensor feedback for
axis Y is requested.
‘Q2E’ requests the sensor
feedback for axis Y.
The electronics will reply
0xFFFFEAE258:
-> 0xFFFFEAE2 corresponds
to a -1.65V sensor feedback.
-> 0x58 at the end corresponds
to the ‘X’ acknowledgement.
This command requests the parameter set of one
axis. This command operates in the same
manner whatever the axis selected.
The electronic answers with 15 x 4 data bytes
followed by acknowledgement character. Each 4
data bytes represent a signed integer value
corresponding to a single parameter. The
parameter readback description is given in the
Table 3: Description of parameter set read back.
1: Requests the
parameter set for axis X
2: Requests the
parameter set for axis Y
‘R1E’ requests the parameter
set for axis X.
This command allows the user to change the
baud rate in fast mode i.e. when the configuration
switch N°1 is up.
The effective baud rate (in Mbps) is:
BR = 11.25/(Reg+1)
Reg = 11.25/BR -1
Please refer to Table 2 : Parameter value for
typical baud rate for typical values.
‘Reg’ is in the range:
[0 ; 65535]
[0 ; 0xFFFF]
‘b11E’ set the baud rate to
937.5kbps
