Product Information
Specifications
- Product Name: EVL Evaluation Encoder
- Encoder Type: Absolute Rotary Encoder
- Resolution Range: 16-23 bits
- Protocols: SSI, BiSS
- Shaft Turn Counter: Optional
- Built-in Test (BIT): Optional
Product Usage Instructions
1. Configuring the EVL Encoder
The EVL encoder can configure 4 parameters:
- Protocol: SSI/BiSS
- Resolution: 16-23 bits
- Shaft Turn: A-B Enable/Disable
- BIT (Built-in Test): Optional
Changing parameters does not require new calibration; initial
calibration remains valid.
Click on “Apply Changes” after making modifications.
2. Resolution Settings
The native bit count varies per encoder model. It is recommended
to use native bit value for better performance, especially in noisy
environments.
3. Software Shaft Turn Counter
This feature is optional and is for applications requiring shaft
counting. Enable the Software Type box before selecting Resolution.
The number of rotations is determined by the selected number of
bits.
4. Built-in Test (BIT)
Enabling this option allows performing a Built-In Test on the
encoder’s operation. Click “RESTORE DEFAULT” to revert to factory
settings.
Frequently Asked Questions (FAQ)
Q: How many bits are available for SSi and BiSS protocols?
A: SSi Protocol has 23 bits available, while BiSS Protocol
offers 20 bits with BIT functionality provided separately.
Q: Is the Software Shaft Turn Counter mandatory?
A: No, it is optional and intended for specific applications
requiring shaft counting.
Q: Can I revert the encoder to factory settings?
A: Yes, you can click on the “RESTORE DEFAULT” button to reset
the encoder.

1. Precision with Flexibility, Engineered for Early Design Implementation
Designing mechanical systems with integrated controls requires precise and adaptable feedback solutions, especially during prototyping. That’s why we developed the EVL Evaluation Encoder: a configurable tool that puts you in control of key encoder parameters from day one. Fully configurable from your workbench Resolution – Adjustable Bits per Revolution Interface – BiSS-C or SSi Software Multi-Turn Counter Built-in Test (BIT) The EVL comes in the standard VL form factor (Ø13247 mm) and is supplied with a 750 mm cable terminating in a female D-type connector, ready for immediate evaluation.
Encoder Explorer software provides full parameter control, plus Limits View to avoid out-of-spec operation Mapping View to understand protocol behaviour and system impact
EKIT Contents When ordering EKITs, you receive encoder and 4 items — or 5 in the case of the VLX family: 1. Blue Box USB to RS-422/485 converter. 2. Cable for connecting the Blue Box to the computer (USB A to B). 3. Dynamic jig varies according to the product size. 4. Cable with a male D-type connector and flying leads for connecting to your controller/system 5. VLX family only Cable with a connector to the encoder on one end and a D-type connector for the Blue Box on the other. By experimenting with different parameter combinations during the evaluation process, you can determine the optimal configuration for your system – leading to a precise encoder part number that you can confidently move forward with for production.

2. How do you configure an EVL encoder?
The EVL encoder can configure 4 parameters:
Parameters Protocol Resolution Shaft turn BIT (built in Test)
Range SSI/ BiSS 16-23 A-B Enable/Disable
Required Must Must Optional Optional
*For your attention, changing the parameters does not require a new calibration, and the initial calibration remains valid.
Note: The maximum bits for the encoder is 32. Therefore, we made a visual Light bar that helps to understand how many you can add.

4. Resolution (in bits)
For each encoder, the native bit count may vary, as there is an option to enable a distinct capability. In noisy environments, using the native bit value is recommended for better performance. Please refer to the native bit table below.

5. Software Shaft Turn Counter
This option is not mandatory and is intended only for applications that require shaft counting. The Software Type box [] must be enabled before selecting the Resolution [bit]. The calculation of the number of rotations is determined by the number of bits you select. For example, if you choose 12 bits, the number of possible rotations will be 4096 (219).
The “Mapping View” can be accessed by clicking on the box.
In this view, you can see how the bits have been allocated according to the requirements you defined for the encoder.

6. Built-in Test (BIT)
This option is also not mandatory. If you would like to perform a BIT (Built-In Test) on the encoder’s operation, you should enable this option.
For your information, you can always click the “RESTORE DEFAULT” button to revert the encoder to the factory default settings as it was shipped from our plant.
