(always reference the manuals that come with your robot) |
|
Robot PM Checks or actions to perform |
| Back up Software (both image and separated files if possible) |
| Clean limit switches and check for free movement |
| Replace robot batteries 1/year |
| Replace RAM B/U batteries 1/year |
| Clear alarms and check cycle power after replacing batteries |
| Clean controller cooling fans, check operation |
| Check fans on drives are running in controller cabinet |
| Check fans exchanging outside air into controller |
| Replace controller air intake filter |
| Control connections |
| Robot cables for damage or wear |
| Robot cable connections |
| Incoming voltage |
| Mechanical hardware for looseness (end of arm tooling, robot base, fixtures, etc.) |
| Axis following error |
| Axis brake functionality |
| Axis vibration- hold hand on axis casting and jog robot in slow and fast speed |
| Axis repeatability and backlash |
| Check belts if used for some of the axis |
|
Robot Grease and oil replacement |
| (Use recommended grease!!! Or Serious damage will occur) |
| Be sure to burp the grease out by moving the robot after pumping through |
| If using a pneumatic or electrical grease gun. Make sure the output pressure is within |
| Robot manufacturers recommendations |
| Move robot to proper position to check oil levels (some models) |
| Axis 1 reducer |
