Polar 115 E/C

Hello
I am new in this forum and need some help with this error: NO REFERENCE POSITION (653) and AUX OPERAT (74)
Polar E/C CP4 V3.0.0-0
Thank you

 

Hi Sir
the problem 1) 74:machine is in the emergency mode.Go to start menu"Scan reference point" Is the only possibilit to operate the machine in case of malfunction or defective in drive unit .
Do this: Remove the malfunction in the drive unit and make a reference Run.Then check backgauge drive functioning and check parameter in service menu "machine data"

2) 653: -No electrical reference pulse is detected during the reference run
-No electrical reference pulse is detected when moving over the reference position stored.
Posssible solution: Make a reference run and move the backgauge along the entire width of the table, if the position mechanical
reference point has been modified
Check funtioning and positioning sensor B 341.
Check cable fro B 341
Check position value in service menu:"machine data"
Check/Replace pulse generator
Checl/replace SAP board.

 

Thak you Sr.
Check and replace the sensor under the table (i do not have schematics or manuals)
