Description
The ASF01 board monitors position information sent from the encoder. If communication error occurs during a control cycle, it monitors based on the last position data. At that time, if the correction data exceeds the specified value, the alarm occurs.
Subcode description
Sub Code: Signifies the axis in
which the alarm occurred
Causes and remedies
| Cause | Remedy |
|---|---|
| Cable (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, check that the following cables and connectors are connected and fully inserted. [Robot axes] • Cable between encoders • SDCA01 board-CN508 • CNBX connectors on the SDCA01 board and ASF01 board [External axis] • Cable between encoders • SDCA01 board-CN534, CN535, CN536 • CNBX connectors on the SDCA01 board and ASF01 board |
| Encoder (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the encoder. |
| ASF01 board (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the ASF01 board. Save CMOS.BIN before replacing the board. |
| Other | If the alarm occurs again after implementing the countermeasures, contact our service department and describe the circumstances when CMOS.BIN was saved (operating procedure, etc.). |
