Chapter 5 Electrical Interface
5.1 Introduction
This chapter describes all the electrical interfaces of the robot and the control cabinet.
These interfaces mainly include:
• Front panel interface of the control cabinet
• Bottom interface of the control cabinet
• Input and output interface of tool flange (TIO)
These three interfaces are described as follows, and use examples of most types of interfaces are provided.
5.2 Electrical Warnings and Precautions
When designing and installing robot applications, you must obey the following warnings and precautions. The
implementation of maintenance must also comply with these warnings and precautions.
File Version: 3.2
Danger:
1. Do not connect safety signals to non-safe PLCs with inappropriate
security levels. If you do not obey the warning, severe injuries or even death
may be caused by the failure of a security stop function. Be sure to separate
the safety interface signal from the ordinary I/O interface signal.
2. All safety-related signals are constructed redundancy (two independent
channels). Keeping two channels separate can ensure that the security
function will not be lost when a single failure occurs.
3. For the introduction of the I/O function in the control cabinet, refer to 5.3.
Danger:
1. Ensure that all equipment strictly prohibited to get wet with water is kept
dry. If water gets in the product, cut off the power in time and contact the
integrator authorized by JAKA.
2. Use original cables of the robot only. Do not use robots in applications
that need to bend cables. Contact your supplier if longer or flexible cables
for frequent bending scenarios are needed.
3. For protective grounding (PE), use the bolt connectors in the control
cabinet to mark the grounding position. The grounding connector should at
least withstand the highest current in the system as its rated current.
4. When installing interface cables on the I/O of the control cabinet, open
the cabinet door, remove the metal board of the cable hole, and ensure that
the I/O cable avoids rubbing with the edge of the cable hole.
Caution:
1. The robot has passed the electromagnetic compatibility test specified in
the corresponding standard. Interference signals beyond the standard will
cause abnormal behaviors of the robot. Extremely high signal level or
excessive exposure will cause permanent damage to the robot. JAKA is not
responsible for any loss caused by the EMC problem beyond the scope.
2. The length of the I/O cable to connect the control cabinet and other
machines or factory equipment must not exceed 30 meters, unless the result
