¨float Cycle-T¨ trip cannot be reset

Which products are affected?
EPL-10200 (Drive PLC V7.2 and lower)
EVS93xxEI (Servo PLC V7.2 and lower)
EVS93xxET (Servo PLC with technology function V7.2 and lower)
ECS axis module: ECSxx operating software V7.4 and lower

What happens?
The float Cycle-T trip (C0168/1 = 210) cannot be reset (e.g. via C0043).

When does the problem occur?
If a numerical overflow or a division by 0 occurs in case of calculations with REAL data type variables, the PLC target system activates the float Cycle-T trip. It is not possible to reset this trip via Trip Reset (C0043 = 0).

Possible diagnostics?
Check if code C0168/1 indicates 210.

Short-term measures/recommendations?
Carry out mains switching of the PLC target system in order to reset the float Cycle-T trip.

Evaluation:
The float Cycle-T trip cannot be reset. This trip is only activated if a numerical overflow or a division by 0 occurs in case of calculations with REAL data type variables. REAL calculations are used quite rarely in Lenze PLC target systems.
