Common Causes

  • MC runs no test of the motor brake line although it is necessary according to parameter settings.
  • The call for testing a brake line lasts longer than 10 seconds.

  1. 1

    Verify the parameters related to motor brake testing are correctly configured, ensuring the test is enabled when necessary.

  2. 2

    Check the motor brake wiring and connections for any damage, looseness, or incorrect installation, including the brake supply voltage.

  3. 3

    Inspect the motor brake unit itself for proper mechanical function, signs of wear, or sticking.

  4. 4

    Monitor the execution time of the brake line test; if it consistently exceeds 10 seconds, investigate potential delays in brake activation or release mechanisms.

  5. 5
