2.5.11. Installation of cooling fan for motors, axes 1-3 (option)
General
A cooling fan can be installed on the motors of axes 1, 2 and 3. However, cooling fans for
axes 1 and 2 can not be combined!
The cabling for the fans is available in different designs:
• complete cabling, including connections for both cooling fans and position switches,
at axes 1, 2 and 3. Installation of this complete cabling is detailed in section
Installation of cable harness for position switches and fans on page 118.
• separate cabling for axis 1 or 2, including only connections for the cooling fans on
axes 1 or 2. Installation of this cabling is detailed in section Installation, separate fan
cabling axis 1 or 2 on page 101.
If both cooling fans and position switches are installed on the robot, the complete cabling
must be used! It can not be combined with the separate cabling.
