Stop!
If the monitoring is switched off, the machine can reach very high speeds in the event of faults (e. g.
system cable is disconnected or not correctly screwed), which can result in the damage of the motor
and of the driven machine! The same applies if "warning" is set as a response.
·
For commissioning, always use the Lenze setting C0586 = 0 (TRIP).
·
Only use the configuration C0586 = 2 (warning) and C0586 = 3 (monitoring switched off) if
monitoring is triggered without any obvious reason (e.g. due to long cables or intense
interference injection caused by other devices). Despite faulty feedback, the pulses are
enabled.
If a fault has occurred in the actual speed detection, it is possible that the overspeed monitoring
(NMAX) does not respond as expected.
·
This monitoring
– is automatically activated if the resolver is selected as an actual speed value encoder under
C0025 (C0025 = 10).
– is automatically deactivated if another actual speed value encoder is selected.
·
The response is set under C0586:
