Problem:

Everything looks fine but the drives do not start if the green button “Production On” is pressed.

Possible Causes & Resolutions:

The main power supply 72 VDC of the Linmot controller is missing:

Check the power supply G5 inside the control panel on the second table (see attached picture). Most probably the 15 Amp. fuse is melted. Replace the broken fuse with a new one.

Problem:

• Speed of the drives changes during production

Possible causes & resolutions:

• Wrong position of the switch for the terminating resistor on the bus plug.
  Check all switches on the complete bus system. Follow the cable thoroughly from first DP bus device (PLC) to last DP bus device. The terminating resistor switch of first and last must be set to „ON”, all other to „OFF“.
• Bus connector/plug defect
• Check wiring of all profibus cables, especially the connection of the cable shield inside the plug.
• Problem of terminating resistor supply by last device on bus. Try to change the profibus wiring to use on another device as last client.
