Application area for these motors is the food and beverage industry, without direct contact with unpacked foodstuffs, according to EN 1672-5.3.2. Applications can be cutting, packing and filling without direct contact with foodstuffs. The motor should be placed laterally or below the food. The motors can be mounted to the linear actuators ERD.
Motors can be ordered with cables or with connectors, both meeting IP69K. For applications where hygiene is critical, we recommend our cable version.
- The one cable solution supports digital feedback system SFD3, and HIPERFACE DSL.
- The two cable solution is necessary for support of Resolver, Comcoder, HIPERFACE, and ENDAT feedbacks.
- Technical data of all available motor windings can be found in the motor manual.
- Technical data of the built-in holding brakes are on page Holding Brake.

|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.
Yes, for the Servostar line it is possible with S300 and S700. See page Cogging Suppression for details. For AKD drive family the feature is available in firmware version 1.15 See Cogging Compensation for details.
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.
