SI MM: Write request for Safety Integrated parameter rejected

What does 230659 mean?

A write request for one or more Safety Integrated (SI) parameters on the Motor Module (MM) was rejected. This typically occurs because an attempt was made to enable a safety function (like STO, SBC, SS1, motion monitoring, or PROFIsafe) that the specific Motor Module does not support, or there is a version mismatch in PROFIsafe drivers. This fault does not trigger a safety stop.

• Attempting to enable or modify a Safety Integrated function (e.g., STO, SS1, SBC) while the drive is not in a safe operating state (e.g., motor running, protective door open).
• The safety acceptance procedure (e.g., S_0_1230 acceptance parameter) has not been correctly performed or acknowledged after parameter changes.
• Checksum mismatch in the safety parameter set, indicating that parameters were modified without proper safety acknowledgement.
• Incompatible firmware versions between the Control Unit (CU) and the Motor Module (MM), leading to safety parameter communication issues.
• Incorrect parameterization of safety-related parameters (e.g., S_0_1230, S_0_1231) required for activating safety functions.

Click steps to track your progress.

1. 1

   1. Ensure the machine is in a safe, de-energized state (e.g., emergency stop active, motor stopped, protective doors closed) before attempting to write SI parameters.

2. 2

   2. Follow the safety acceptance procedure outlined in the drive safety manual, specifically acknowledging changes using the relevant acceptance parameter (e.g., S_0_1230).

3. 3

   3. Verify that the firmware versions of the Control Unit and all Motor Modules are compatible according to the manufacturer's documentation.

4. 4

   4. Use the Safety Integrated commissioning tool (e.g., within STARTER or Startdrive) to check the integrity and consistency of the safety parameter set.

5. 5

   5. If attempting to enable a specific safety function, ensure all preconditions for that function are met (e.g., input signals, internal states).
