Time interval of forced dynamization exceeded

What does E3110 mean?

The configured time interval for forced dynamization (a safety function test) has been exceeded, meaning the safety function test has not been performed within the required period. This typically leads to a safety-related shutdown.

• The drive has not been brought to a standstill or the required safety function test has not been initiated within the parameterized interval.
• Safety controller or PLC logic is not commanding the dynamization test.
• Incorrect parameterization of the forced dynamization interval.
• Issue with the safety feedback loop preventing the test from completing.

Click steps to track your progress.

1. 1

   Initiate the forced dynamization (safety function test) as required by the safety concept and machine documentation.

2. 2

   Review the safety PLC or machine control program to ensure the dynamization test is being commanded correctly and periodically.

3. 3

   Verify the parameter setting for the forced dynamization interval and adjust if necessary, according to safety regulations and application needs.

4. 4

   Check the safety feedback signals and wiring to ensure the test can be properly executed and acknowledged by the drive.
