001135 (CR Motor Cable Disconnection Error)
Error contents
- A fixed current is supplied to the CR motor and motor rotation is observed by the scale and encoder and the presence of an encoder signal is checked, but no signal is detected correctly.
- The CR Encoder cannot detect the value of the CR Scale.
- CR Unit operation cannot be detected.
Suspected cause
- CR Encoder failure
- CR Motor failure
- CR Motor cable connection abnormality/broken
- CR Encoder FFC cable connection abnormality (connection, broken)
- CR Scale coming off
- CH83 SUB (On-CR) Board failure
- CH83 DRV-H Board failure
- CH83 Main-B Circuit Board failure
Parts/Components to be checked
- CR Scale
- CR Motor
- CR Encoder
- CR Encoder FFC cable
- CH83 SUB (PW/IMS) Board
- CH83 DRV-H Board
- CH83 Main-B Circuit Board
Troubleshooting
| Step | Confirmation points and methods | Page | YES | NO |
|---|---|---|---|---|
| 1 | Check for abnormalities in CR operation
Does the product recover from the error? | --- | End | Go to step 2 |
| 2 | Check if the CR Scale is coming off the CR Encoder. Does the product recover from the error? | CR Scale | End | Go to step 3 |
| 3 | Check if there are any abnormalities in the CR Motor cable connection. If an abnormality is found, reconnect it. Does the product recover from the error? | CR Motor | End | Go to step 4 |
| 4 | Replace the CR Motor. Does the product recover from the error? | CR Motor | End | Go to step 5 |
| 5 | Check the FFC connection of the CR Encoder, and reconnect it. Does the product recover from the error? | CR Encoder | End | Go to step 6 |
| 6 | Replace the CR Encoder. Does the product recover from the error? | CR Encoder | End | Go to step 7 |
| 7 | Replace the CR Unit (including CR Encoder Sensor cable). Does the product recover from the error? | CR Unit | End | Go to step 8 |
| 8 | Replace the CH83 SUB (PW/IMS) Board. Does the product recover from the error? | CH83 SUB (PW/IMS) Board | End | Go to step 9 |
| 9 | Replace the CH83 DRV-H Board. Does the product recover from the error? | CH83 DRV-H Board | End | Go to step 10 |
| 10 | Replace the CH83 Main-B Circuit Board. Does the product recover from the error? | CH83 Main-B Circuit Board | End | Escalate to person in charge |
