To identify more complex issues, the CMMO-ST provides several diagnostic methods:
Check the motor cable for breaks and ensure the encoder is properly connected. Verify that the holding brake is releasing correctly if one is integrated. Diagnostic Interface Overview
Verify that both safety channels are receiving identical signals. Inspect the safety relay or PLC output providing the STO signal. 3. Communication Timeout cmmo-st-c5-1-diop error codes
This often indicates a discrepancy between the two safety channels ( STO1 and STO2 ) at the [X3] connector or a logic failure in the safety circuit.
Protects the motor and power stage from thermal overload. To identify more complex issues, the CMMO-ST provides
The is a compact stepper motor controller widely used in industrial automation for precise positioning tasks. Like any sophisticated piece of automation hardware, it can encounter errors related to power, communication, or safety systems.
The logic supply voltage at the [X9] connector has dropped below the required threshold (typically 24V DC ±15%). Inspect the safety relay or PLC output providing
A dual-channel safety function (Category 3, PL e) that safely disconnects the power to the motor.
