Absolute value encoder EnDat® 2.1 or EnDat® 2.2
- Optical or inductive measuring principle
- High system accuracy with up to 23 bits resolution 
- Up to 4096 recordable resolutions in multiturn version
- Electronic nameplate ensures fast and easy commissioning
- Additional information transferred with the position value (EnDat® 2.2)
- Compatible with STOBER drive controllers and drive controllers of many third-party manufacturers

- High temperature resistance
- High vibration strength and shock resistance

Power and Encoder Interface

- Rotating plug connectors with quick lock.
- Option: Supplied with mating connectors.

Encoder One Cable Solution (OCS)

HIPERFACE DSL One Cable Solution (OCS)
- Significantly reduced wiring effort by eliminating the encoder cable
- Significantly reduced space requirements by eliminating the encoder plug connector
- High system accuracy with up to 20 bits resolution 
- Up to 4096 recordable resolutions in multiturn version
- Electronic nameplate ensures fast and easy commissioning
- Additional information transferred with the position value

Power and Encoder Interface One Cable Solution (OCS)

- Rotating plug connector with quick lock (connection lines between the encoder and drive controller are routed along in the motor's power cable).
- Option: Supplied with mating connector.

Winding Protection

PTC thermistors are installed in STOBER synchronous servo motors as a configuration feature to implement thermal winding protection. This makes it possible for the motor to exceed the maximum permitted winding temperature with the appropriate devices turned off.

Drive Controller Recommendation

- POSIDRIVE MDS 5000 with power range 0.75 to 45 kW
- POSIDYN SDS 5000 with power range 0.75 to 45 kW
- SD6 with power range 0.75 kW to 45 kW
- SI6 with power range 0.75 kW to 25.9 kW



What drives the requirement for accurate, high-quality labels? With so much hanging in the balance for manufacturers and retailers competing on a global scale, there's no good reason to ignore the need for label quality. Mislabeled packaging could have consequences that range from wasted product to (potentially severe) consumer health issues.

Let's take a look at four major areas that illustrate the importance of ensuring the accuracy and legibility of product and packaging labels and discuss a solution that can help avoid errors.

Area 1: General product traceability

Product traceability, in a general sense, is essential for consumer safety, regulatory compliance and overall quality perception. If there’s a problem with a product, traceability allows the consumer, retailer or another entity to quickly locate and segregate defective products in the event of a recall.
