2.1 Introduction to motor units and gear units
Product overview
The motor units and gear units function as external axes in the IRC5 system. They
are controlled by drive units mounted in the IRC5 controller. The units are designed
for optimal performance, installation, and application.
The motor units and gear units use much of the same components and are therefore
described together.
SMB box
The SMB box (optional) contains a serial measurement board (with battery backup)
and brake release buttons (optional).
Note that if the motor unit is used in an arc welding station, the SMB box must
always be insulated from the weld circuit. See
Insulation in arc welding stations
on page 64 .
Axis selector
The axis selector (optional) is mounted inside the IRC5 controller and makes it
possible to cut the power for selected connected external units. The function is
controlled by instructions in the robot program.
