1.2 Document Guidance
The subsequent chapters describe the type of service work possible to carry out by the
Customer’s own service staff on location. Some service wors requiring special experience or
special aids are not described in this manual. The latter work requires replacement of the
failed

or
component
on
location.

ROBOTICS for service.
Commutation. A re-commutation has to be carried if a motor has been separated from its
feed back unit. The procedure is detailly described in Chapter 8, Commutation.
Calibration. A new calibration of the robot has to be carried out after replacing
mechanical unit parts or when the motor and feedback unit have been separated, a resolver
error has occurred or when the power supply between measurement board and resolver has
been interrupted. The procedure is described in detail in Chapter 9, Calibration.
A
Any work on the robot signal cabling may result in the robot moving to incorrect
positions.
After performing such work, the robot calibration position must be checked
according to chapter 9, ”Calibration”..
Tools. Two types of tools are required for the various service works, on one hand
conventional tools like sockets and ratchet spanners, etc. On the other hand special tools
may be necessary to use, depending on what type of service being carried out. The
conventional tools are not dealt with in this manual, based on the assumption that the
service personnel has sufficient technical basic competence. Service works requiring use of
special tools are described in this manual.
Foldouts. The manual's Spare Part chapter is provided with a number of foldouts
illustrating the robot's details to facilitate a quick identification of both the type of service
required, both the composition of the various details and components. The details are
position numbered on the foldouts. Those numbers are referred to in the Manual text
within "arrow heads” (< >). Where reference is made to other foldouts than specified in the
paragraph title, the foldout's number is included in the position number reference, for
example <5/19> or <10:2/5>, the digit(s) before the stroke referring to the foldout number.
The foldouts also include information such as article number, designation and
corresponding data.
N.B. This manual is not to be considered as a substitute for a proper training
