Cause : Illegal monitoring clock cycle comes when one of the Safety Integrated monitoring clock cycles is not permissible.

- the monitoring clock cycle integrated in the drive cannot be maintained due to the communication conditions required in the system.
- the monitoring clock cycle for safe motion monitoring functions is not permissible (p9500).
- the actual value sensing clock cycle for safe motion monitoring functions is not permissible (p9511).
- The sampling time for the current controller (p0112, p0115[0]) cannot be supported.

1. For enabled SI monitoring integrated in the drive (p9601/p9801 > 0): - Upgrade the firmware of the Control Unit to a later version.
2. For enabled motion monitoring function (p9501 > 0): - correct the monitoring clock cycle (p9500) and carry out POWER ON.
