Drive Diagram - Motor Documentation

[Tasty_Tech]

Hello All,

I was looking in to the speed- torque diagram in the documentation.

Could anyone please help me understand the Light blue dotted line and Dark blue dotted line in the drive diagram? Please find the screenshot below. I would also like to know why its is suddenly decreasing to zero at speed 4000 in first diagram ? if we had coupled the motor with the ctrlx Drive then I can understand that drive might restrict the motor performance but in this case why there is dotted blue lines.

Thank you in advance for your answer.

The light blue or dark blue dotted lines contrary to the solid light blue or dark blue lines are valid for operation in conjunction with drive amplifiers which have no capabilities in making the field weakening area work (like older firmware versions with IndraDive) or where the parameters are set in a way that field weakening is not activated.

The difference between the first diagram is operated at at a non-controlled power supply unit like XVE or XCS at mains voltage 3x AC 400 V whereas the second diagram shows the behavior at controlled power supply unit like XVR where the mains voltage doesn´t matter.
