Possible Causes & Resolutions:

• No supply of a Profibus participant (slave) on the bus system.
  • Check 24Vdc supply of Linmot controller. Is supplied by 24Vdc terminal X10. For more details check wiring diagram.
  • Check 400Vac supply of Pacemaker. The circuit breaker Q5 may have tripped. For more details check wiring diagram.
• Address of Profibus on Linmot controller is set wrong.
  • Check the two rotary switch S1 and S2 on front side of Linmot controller. Both should be set according wiring diagram.

• Dip switch for interface on Linmot controller is set wrong.
  • Check the Dip switch S3 on bottom side of Linmot controller. Dip switch 4 must be set to ON to activate the Profibus interface, all other must be set to OFF.

• Wrong position of the switch for end resistant on the bus plug.
  • Check all switches on the complete bus system. Follow the cable seriously from first to last Profibus participant . Plug of first Profibus participant and plug of last Profibus participant must be set to ON, all other to OFF.
• Pacemaker™ settings lost because of empty ram battery
  • Replace battery. You can find more information here => Pacemaker – Support (canman.ch)
  • If the ram battery of the Pacemaker is empty and the settings are lost, the profibus communication may no longer start and also the analogue outputs, which control the speed for the wire drive and downstacker, are switched off (0Vdc).
  • After a battery change, the Pacemaker™ may have to be rebooted 3 – 4 times. To do this, disconnect Pacemaker™ from the mains and reconnect it (fuse breaker Q5 off and on again). Check the parameter settings before start the welding machine. If you have no access please open a ticket to get support => Can Man Support

• PLC program has been lost due to empty ram battery and missing program on the memory card. Red LED IF is on.
  • Program has to be loaded again by DP/MPI adaptor and laptop with installed Siemens Step7 software or from memory card (MMC) with program file. => Contact Canman.
  • Possibly PLC or memory card are defective and has to be replaced.
  • Important: The ram battery in the PLC cannot be replaced! This is charged when the machine is switched on and guarantees that the program is retained for a maximum of 30 days. If the PLC loses the program due to an empty ram battery, it automatically loads it from the memory card (MMC) when the machine is started. Of course only if a memory card is inserted and there is a valid file on it.
