5.9.1 General settings
Encoder open-circuit monitoring
In the Lenze setting the resolver/encoder cable is monitored for open circuit.
When does the open-circuit monitoring system respond?
0x2C45 | 0x3445 - feedback system: Response to open circuit
Display parameter
0x2C46 | 0x3446 - feedback system: Specifiable number of revolutions
Danger!
If the encoder/resolver is used as motor encoder:
Safe operation of the motor is no longer ensured in the event of an error!
• For safety reasons, always select "Fault" (Lenze setting) as a response for the (open-
circuit) monitoring of the encoder/resolver!
• To avoid the injection of interference when an encoder is being used, only use
shielded motor and encoder cables!
Resolver Multi encoder
• If there is an open circuit in the encoder cable.
• If the impedance of the resolver is too high.
• In the case of interference injections (EMC
interferences).
• If there is an open circuit in the encoder cable.
If there is an open circuit in the encoder cable, the response set here is triggered.
Selection list (Lenze setting printed in bold) Info
0 No response
1Fault • In the device statuses "not ready to start" and "switch-
on inhibited", a warning is output.
• In all other device statuses, the error response set
here is executed.
