4 Electrical Interface
4.1 Introduction
This chapter describes all the electrical interfaces of the robot arm and control box.
The different interfaces are divided into five groups with different purposes and prop-
erties:
• Controller I/O
• Tool I/O
• Ethernet
• Mains connection
• Robot connection
The term “I/O” refers both digital and analog control signals going from or to an
interface.
These five groups are described in the following sections. Examples are given for most
types of I/O.
The warnings and cautions in the following section are relevant for all five groups and
must be observed.
4.2 Electrical warnings and cautions
The following warnings and cautions must be observed when a robot application is
designed and installed. The warnings and cautions also apply for service work.
DANGER:
1. Never connect safety signals to a PLC which is not a safety
PLC with the correct safety level. Failure to follow this warn-
ing could result in serious injury or death as one of safety stop
functions could be overridden. It is important to keep safety in-
terface signals separated from the normal I/O interface signals.
2. All safety-related signals are constructed redundantly (Two in-
dependent channels). Keep the two channels separate so that a
single fault cannot lead to loss of the safety function.
3. Some I/O inside the control box can be configured for either
normal or safety-related I/O. Read and understand the com-
plete section 4.3.
