CCBU40 COMPACT CONTROLLER BOARD - PRODUCT AND WARRANTY INFORMATION
Version 1.21
V.2. CCBU40 CONFIGURATION
FACTORY CONFIGURATION
On customer request and depending on the associated mechanism, the CCBu20 could have the following
configuration:
•
Sensor conditioning
In default configuration, the CCBu40 is equipped with a sensor conditioning. When the associated mechanism
is already equipped with a sensor conditioning (a strain gauge or any other sensor with integrated conditioning
stage providing a ±10V signal).
This information is given in the mechanism user manual.
•
Closed loop order
In default configuration, the gain between the sensor feedback and the analog command is 1. Which means
that if the sensor feedback is between -4V and +4v for the full mechanism stroke, the user must send an analog
order between -4V and +4V to reach the full stroke.
Some other configurations are available. The gain could be higher to maximise the input voltage resolution
measurement (the maximum is for an analog signal between -10V and +10V). An offset could be added (for
example to have an analog input voltage only positive).
This information is given in the mechanism Factory Verification
Sheet in the ‘displacement VS input voltage in
close loop’ test.
USER CONFIGURABLE CONFIGURATION
•
Control parameters
In default configuration the control parameters are the following: P=0.05, I=200, D=0. Output filter is a second
order lowpass filter with cutoff frequency of 200Hz.
When the CCBu40 is associated with a mechanism, these parameters could be tuned to reach the mechanism
performances. This information is given in the the mechanism Factory Verification Sheet.
•
Configuration switches
3 mode selections switches are present on the CCB. The position of the switches must be set before the CCB
power up.
o
Switch 1
When this switch is down (default configuration) the RS communication is forced to 57600 bauds. When this
switch is up, the RS baud rate is set to the user configurable one. On delivery, this speed is set to 937.5kbps.
For more information refer to chapter XI.
o
Switch 2
When this switch is down, it forces the CCB on analog command. The user must send the movement order on
the AiX and AiY input.
When this switch is up (default configuration) the user can select, through the RS communication, the order
mode (analog or digital). On delivery the analog mode is set.
o
Switch 3 (reserved)
This switch must always remain up
