Okuma OSP Alarm C 3698 - MCS Linear scale 1 initialization failure
The control failed to initialize Linear scale 1 (MITUTOYO) on the axis shown in the object field. The code field carries the same XXYYZZZZ detail as alarm 0865 MCS Encoder initialize failed.

Okuma OSP Alarm C 3698 - MCS Linear scale 1 initialization failure
MCS Linear scale 1 initialization failure
The control failed to initialize Linear scale 1 (MITUTOYO) on the axis shown in the object field. The code field carries the same XXYYZZZZ detail as alarm 0865 MCS Encoder initialize failed.
Common Causes
- Faulty Linear scale 1 (MITUTOYO)
- Faulty motor encoder
- Encoder link cable or connector problem
- Faulty control base of the inverter unit
Troubleshooting Steps
- 1Read the code number shown with the alarm: code XXYYZZZZ = Same decode as alarm 0865 MCS Encoder initialize failed
- 2Note the axis name in the object field and record the XXYYZZZZ code value, which is decoded the same way as alarm 0865 MCS Encoder initialize failed.
- 3Lock out the machine and inspect the Linear scale 1 (MITUTOYO) read head and scale tape for coolant, chips or physical damage; clean carefully if contaminated.
- 4Check the encoder link cable and connectors between the scale and the inverter unit for damage or poor contact; reseat or swap with a known-good cable.
- 5The manual also lists the motor encoder and the inverter unit control base as suspects: swap or substitute these one at a time to isolate the faulty item.
- 6If it returns after these checks, record the alarm number, code and object and contact Okuma service.
