Omron · NJ/NX-series Machine Automation Controller
A missing serial incremental encoder phase-Z pulse was detected. This means the encoder is not providing its reference zero-position pulse correctly, essential for accurate homing and absolute positioning.
Click steps to track your progress.
Inspect the serial incremental encoder cable for physical damage, proper routing, and secure connections at both the encoder and the Omron NJ/NX controller's input module.
Verify the encoder's power supply voltage at its input terminals against the manufacturer's specifications to ensure stable operation.
Check the encoder configuration parameters within the Omron Sysmac Studio project, specifically verifying the encoder type, resolution, and Z-phase input settings.
Examine the mechanical coupling between the encoder and the motor shaft for looseness, slippage, or damage that could prevent accurate pulse generation.
