Okuma OSP Alarm A 1692 - MCS Linear scale 4 initialization failure
MCS Linear scale 4 initialization failure
The MCS drive failed to initialize linear scale 4 (an auxiliary/other scale) on the axis named in the object during power-up. The axis has no valid scale feedback until initialization completes.
Common Causes
- Failed linear scale 4 unit
- Scale cable or connector fault preventing the initialization handshake
- Scale power supply problem from the drive
- Contamination or damage at the scale read head
Troubleshooting Steps
- 1Identify the axis from the alarm object and inspect the cable and connector of linear scale 4 for damage, oil ingress or bent pins; reseat both ends.
- 2Cycle power and watch whether the scale initializes; a persistent failure on the same axis points to the scale or its dedicated cable rather than a transient glitch.
- 3Swap the scale cable with a known-good cable to rule out a wiring fault before condemning the scale.
- 4If wiring is good, replace linear scale 4 with the specified unit as the manual's corrective action directs, then re-establish the axis reference position.
