Notes:
• Intermediate values are not permitted (parameterization error).
• Exceeding the computing time on the speed controller clock cycle level is not permissible
and will lead to tripping of the drive.

The interrupt clock cycle is used for high-priority monitoring purposes. Note: The input value
for the clock cycle must be a whole multiple of 4 ms (parameterization error). For the default
value, the monitoring cycle time is 100 ms.
m x 4000 µs m = 1, 2, 3 ... 25
Note:
The interrupts level must not be exceeded. If it is, the drive shuts down.
