Setting possible
This monitoring function monitors the resolver cable and the resolver with regard to open
circuit and protects the motor.
Stop!
If monitoring is disconnected, the machine can achieve very high speeds in
case 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.
ƒ
For commissioning C0586, always use the Lenze setting (TRIP).
ƒ
Only use the possibility of disconnection via C0586 if the monitoring is
activated without apparent reason (e. g. by very long cables or intense
interference injection of other drives).
ƒ
Configure C0586 = 2 (warning) only on the above−mentioned condition,
because the pulses are enabled despite faulty feedback.
If a fault with regard to the actual value acquisition is available, it is not
definitely ensured that monitoring is triggered by overspeed (NMAX,

is automatically activated if a resolver is selected as an actual speed value encoder
via C0419.

is automatically activated if another actual speed value encoder is selected.
The response is set via C0586.
