Hii

I'm using simocode pro s for DOL( crusher) feeder. I have given hardware interlock in series for another(belt conveyor) feeder. If I switch off belt conveyor, then crusher getting off. It is due to interlock. But after crusher feeder getting off simocode having feedback off fault. 

How to avoid this fault ?

Split from SIMOCODE giving odd feedback off fault.

Hi,

first of all i would check the manual for that failure:

There you will find informations regarding Troubleshooting (PDF-Page 330)

SIMOCODE pro monitors the status of the feeder (ON or OFF) via FB ON. If the status of FB ON changes - without a corresponding switching command - "Fault-Feedback(FB)" switches off the feeder.

Default setting: 0.5 s

Thefeedbacktime can be used to suppress such "feedback faults" for a defined period of time, e.g. in the case of network switchover.

When the motor is switched off, SIMOCODE pro continuously checks whether FB ON = 0.

If the current flows longer than the setfeedbacktime without the "ON" control command being issued, afaultmessage "Fault-feedback(FB) ON" is issued. The contactor controls can only be connected after thefaulthas been rectified.

When the motor is switched on, SIMOCODE pro continuously checks whether FB ON = 1. If no current flows for longer than the setfeedbacktime without the "OFF" control command being issued, afaultmessage "Fault-feedback(FB) OFF" is issued. The contactor controls are deactivated.
