Man Roland 305

Need help with the following error

Speed Reading: Malfunction
See picture

 

hello,
check following things
1. main drive motor encoder
2. encoder cable and plugs
3. armature and field supply
4. D.C drive input supply
5. brake is releasing?

 

see the video: https://youtube.com/shorts/xsHwZXDtMPU?si=MJU76WVXh2e1N4N5

Brake releases but engages again right away
Encoder cables are good and continuity are good in all pins

 

I need more details about the trouble you are having with the machine. You may have other errors from UWR/RTR or the machine control system.

 

Guards errors are cleared only know errors currently are that of the empty water the moment we try to jog motor reacts but cuts out and we get the “ speed reading malfunction “ error the brake releases but seems to engage right away

 

Is this a new installation or did the machine stop during operation?

 

Uhmmm other video

 

Yes this is a new installation

 

write down the machine series and attach the UWR slot 9 picture

 

Check the RTR to HA inverter cable. And the encoder signals.
!!!! RUESTEN (make ready) on the center console.

 

I think.... I need to see status of main motor controller. machine séries ? Main drive is Siemens?? Baumüller ? I suppose you have checked make ready function.... Then as druckman says you must check RTR to HA . All coneztion from encoder main drive etc. another think... you must release brake by hand and looking in the RTR input encoder there you.cam see each bit, but... don't looks for my an encoder failure for example ... If encoder error occurs machine must turn and then fail. There's many possibilities of failure

 

you can change A358/04 slot card

 

Change encoder motor
