8.3 Checking Robot Mounting Bolts
Check the tightness of the base mounting bolts every 6 months. Refer to Table 3-2 on
page 44 for torque specifications.
8.4 Checking Robot Gear Drives
Adept Quattro s650H robots use gear drives, which use oil in their components for
lubrication. It is recommended that you periodically inspect the robot for signs of oil on
and around the gear drives.
NOTE: Check the operation of the fans while the motor covers are off.
See Section 8.5.
1. Remove all power to the robot before starting this check.
2. Wait for the motors to cool before performing this check.
3. Check for oil inside the base of the robot after removing the motor covers.
• Look through the venting slots under each motor for oil leakage.
• Feel the bottom of the motors with your finger through the venting slots.
4. Check the outside of the motors and gear drives for any signs of oil.
5. Contact Adept if you find any signs of oil in these areas.
8.5 Checking Fan Operation
The motor fans are PWM controlled. This needs to be done with 24 VDC to the robot ON
Verify that all four motor fans operate:
1. Remove all motor covers.
2. Toggle power to the AIB.
Motor fans run for about 1 minute before shutting off. (If the robot is hot, they will
continue to run.)
3. Verify that each motor fan is running.
4. Verify that the AIB fan is running.
NOTE: The AIB fan runs continuously, but its speed will vary.
5. Reinstall all motor covers.
WARNING: Do not remove the encoder cable connectors
from their sockets on the motors. If they are removed, the
calibration data will be lost and the robot must be
recalibrated, which requires special software and tools
