Page 5: Safety
Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture and intended use of the device. • WayCon assumes no liability for the costumer’s failure to comply with these requirements. 1.2 Electrical safety •... -
Page 6: Mounting Instructions
- 6 - 2. Mounting instructions 2.1 Dimensions 2.2 Magnetic Tape Only pair the sensor with magnetic tape WBA2. For detailed information on the WBA2 magnetic tape and how to mount it please refer to its installation guide. The figures 1 and 2 shows how the sensor and the tape must be installed. Please note that the WBA2 magnetic tape is fitted with two tracks: an absolute track on one side and an incremental track on the other side. - Page 7 - 7 - Figure 2 Please note that the WBA2 magnetic tape can be equipped with a stainless-steel cover strip (provided in delivery) to protect its magnetic surface. Therefore, the distance between sensor and tape is different whether the cover strip is applied or not. The following table shows the range within which the distance between sensor and magnetic tape must be: Distance (D) between sensor and magnetic tape...

Position control register to perform an automatic position control. ATTENTION: The use of both the Position control register and this Warning bit is strictly reserved to WayCon technicians. 5.2.4 CRC (6 bits) CRC (Cyclic Redundancy Check) is the error checking field resulting from a “Redundancy Check” calculation performed on the message contents. -
Page 14: Control Data Cd
- 14 - 5.3 Control Data CD For complete CD structure information please refer to the official BiSS documents: “Protocol description C- mode”. Main control data is described in the section below. 5.3.1 Register address (7 bits) This is the address of the register. It specifies the register you need to read from or write to. 5.3.2 RW (2 bits) It sets whether you need to write to register (RW = “01”) or to read from the register (RW = “10”). -

MXS2-BISS-10-... MXS2-BISS-5-... MXS2-BISS-2-... MXS2-BISS-1-... See “Standard encoder profile”, “data format”, “Variant 0-24”. -
Page 16: Command
As soon as the command is sent the default parameters are uploaded and activated. All parameters which have been set previously are overwritten, thus previously set values are lost. The complete list of machine data and the relevant default parameters preset by WayCon are available at the last page of this manual. -

- 17 - Enable preset / offset It enables / disables the preset / offset functions. After having enabled the use of the functions you have to choose whether to activate the preset or the offset in the Set preset / offset parameter. Then to activate a new value, set it next to the Preset / Offset register and send the Save and activate Preset / Offset command (set “02”... -
Page 18: Device Type
- 18 - Preset The Preset function is meant to assign a value to a desired physical position of the sensor. The chosen physical position will get the value set next to this item and all the previous ad following positions will get a value according to it. -
Page 19: Position Control
This is used along with the Warning bit (see on page 13) to perform an automatic position control. Default = 00h ATTENTION: Do not change the value in this register, its use is strictly reserved to WayCon technicians. 5.5 Application note Device communication specifications: Parameter... -
Page 20: Ab Incremental Output Signals
2000 Interpolation factor = 40 Thus, in the case of the MXS2-SSII-50-… sensor, the system will provide 40 AB pulses per each pole. NOTE: Please note that the Counting direction parameter available in the BiSS-C interface (see on page affects the absolute position information, not the AB incremental signals. -

Page 22: Maintenance
- 22 - 8. Maintenance The magnetic measurement system does not need any particular maintenance. It should be handled with utmost care as any delicate electronic equipment. From time to time we recommend the following operations: • Periodically check the soundness of the structure and make sure that there are no loose screws. Tighten them if necessary. -
