DBL / DBK
The synchronous servomotors of the series DBL/DBK are brushless three-phase motors for high quality servo-applications. This is a Service product: the DBL/.DBK servo motors are not available for new applications but replacement motors are available.

|DBL / DBK with Encoder||Feedback has no defined commutation offset. The commutation offset is determined with the help of the servo amplifier and stored in the encoder memory.|
|AKM with Hiperface encoder||Encoder is installed arbitrarily. The commutation offset is determined with the aid of the servo amplifier and stored in the encoder memory.|
|AKM with BiSS encoder||Encoder is installed arbitrarily. Commutation offset is set to zero electronically.|
|AKM with EnDat encoder||Commutation offset is mechanically set to zero.|
That depends on the servo amplifier that is used.
See page Synchronism.
That is an AKM72M (480V). A list of all motor numbers can be found in the Motor Database, available from the Downloads page.
See page Four Quadrant Operation.
No, this is forbidden. Connecting a motor directly to the main supply will destroy the motor. Refer to the chapter "Use as directed" in the instructions manual.
See the Reference table.
Low rotor inertia is the source for this problem, ironless linear motors show a similar behavior.
Solution for drives with S300/S700 servo amplifiers:
Increase the bandwidth of the current control loop with the Smith Predictor (FILTMODE = 2). Refer to page Tuning: Delay Time Compensation with Smith Predictor.
