5.9. Serial Measurement Board memory
Serial Measurement Board, SMB
The Serial Measurement Board, SMB, primarily gathers resolver data from the robot’s (or
additional axes) motors. This data is used to measure the speed and position of each axis.
Each SMB is capable of measuring up to 7 axes. It also stores a number of data pertaining to
each robot.
This data is used by the controller and can be transferred between the SMB and the controller.
Normally, the data is transferred automatically, but it can also be done manually.
The SMB data is affected when:
• the robot is replaced
• the SMB is replaced
• the controller (or its flash disk or mass memory unit) is replaced.
• updating with new calibration data
The following data is stored on the SMB:
• serial number for the mechanical unit
• joint calibration data
• SIS data (Service Information System)
Note that if the IRC5 controller is to be connected to a robot with an older SMB, not equipped
with data storage capability, the SMB must be replaced.
SMB data update
If... then...
the flash disk or mass memory or the
complete controller is new or replaced by an
unused spare part...
the data stored in the SMB is automatically
copied to the controller memory.
the SMB is replaced by a new, unused, spare
part SMB...
the data stored in the controller memory is
automatically copied to the SMB memory.
the flash disk or the complete controller is
replaced by a spare part, previously used in
another system...
the data in the controller memory and the
SMB memory is different. You must update
the controller memory manually from the
the SMB memory.
the SMB is replaced by a spare part SMB,
previously used in another system...
the data in the controller memory and the
SMB memory is different. You must first clear
the data in the new SMB memory, and then
update the SMB memory with the data from
the controller memory.
new calibration data has been loaded via
RobotStudio Online or using the FlexPendant
and the system has been restarted...
the data in the controller memory and the
SMB memory is different. You must update
the SMB memory manually from the
controller memory.
Check that the new calibration values belong
to a manipulator with the serial number
defined in your system.
