4.1.2 Instructions for reading the following sections
The subsequent sections describe the type of on-site maintenance that can be performed by
the customer's own maintenance staff. Some maintenance jobs require special experience or
specific tools and are therefore not described in this manual. These jobs involve replacing the
faulty module or component on-site. The faulty component is then transported to ABB for
service.
Calibration
The robot must be re-calibrated when a mechanical unit or part of one is replaced, when the
motor and feedback unit is disconnected, when a resolver error occurs, or when the power
supply between a measurement board and resolver is interrupted. This procedure is described
in detail in section Calibration information on page 131.
Any work on the robot signal cabling may cause the robot to move to the wrong posi-
tions.
After performing such work, the calibration position of the robot must be checked as
described in section Calibration information on page 131.
Tools
Two types of tools are required for the various maintenance jobs. It may be necessary to use
conventional tools, such as sockets and ratchet spanners, etc., or special tools, depending on
the type of servicing. Conventional tools are not discussed in this manual, since it is assumed
that maintenance staff have sufficient basic technical competence. Maintenance jobs which
require the use of special tools are, on the other hand, described in this manual.
Foldouts The chapter on spare parts comes with a number of foldouts which illustrate the parts of the
robot. These foldouts are provided in order to make it easier for you to quickly identify both
the type of service required and the make-up of the various parts and components. The item
numbers of the parts are also shown on the foldouts.
In the subsequent sections, these numbers are referred to in angle brackets < >. If a reference
is made to a foldout, other than that specified in the paragraph title, the foldout's number is
included in the numeric reference to its item number; for example:
<5/19> or <10:2/5>. The digit(s) before the stroke refer to the foldout number.
The foldouts also include other information such as the article number, designation and
related data.
NB! This manual is not considered as a substitute for a proper training course. The informa-
tion in the following chapters should be used only after an appropriate course has been com-
pleted.
