6.7 Checking Fan Operation
The robot uses fans to cool the motors. The 24 VDC Control Power will need to be applied to
the robot during this procedure.
Use the following procedure to check the fan operation on joints 1 and 2.
1. Ensure the motors are cool before performing this check.
2. Remove the iCS-ECAT but do not disconnect any cables. Refer to Replacing the iCS-
ECAT Unit on page 113 for more information.
IMPORTANT:
Do not remove the encoder cable connectors from their
sockets on the motors. If they are removed, the calibration data will be lost
requiring factory recalibration.
3. Turn Control Power ON to the robot. This will start the fans and they will continue to
run for about 1 minute. Verify that joint 1 and joint 2 fans are running by looking
through the iCS-ECAT opening.
4. After checking the fans, turn Control Power OFF.
5. Reinstall the iCS-ECAT to complete this procedure. Refer to Replacing the iCS-ECAT
Unit on page 113 for more information.
