Click steps to track your progress.

1. 1

   Reduce the programmed feed rate and shaft speed before opening the safety doors or engaging SRG operating mode.

2. 2

   Verify the position of the key-operated switch to ensure the correct operating mode (e.g., BA2, BA3, BA4, Special operation) is selected and active.

3. 3

   Check the parameter values: MP540.x/MP541 (Operating mode BA3/BA4), MP552.x/MP551 (Special operation), and MP590.x/MP591 (Operating mode BA2) to confirm their settings match the machine's safety configuration.

4. 4

   Inspect the safety door interlocks and the axis speed monitoring system for proper function and calibration.
