1.1 Safety
 Always adhere to the professional safety and accident prevention regulations
applicable to your country during device installation and operation;
 installation and maintenance operations have to be carried out by qualified
personnel only, with power supply disconnected and stationary mechanical
parts;
 device must be used only for the purpose appropriate to its design: use for
purposes other than those for which it has been designed could result in
serious personal and/or the environment damage;
 high current, voltage and moving mechanical parts can cause serious or fatal
injury;
 warning! Do not use in explosive or flammable areas;
 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 equipment;
 Lika Electronic assumes no liability for the customer's failure to comply with
these requirements.
1.2 Electrical safety
 Turn off power supply before connecting the device;
 connect according to explanation in the "4 - Electrical connections" section
on page 9;
 if not used, connect Preset / Offset and Counting direction inputs to 0Vdc;
- to set the Preset / Offset, connect Preset / Offset input to +Vdc for 100 µs at
least, then disconnect +Vdc; normally voltage must be at 0Vdc; zero must be

  • Page 11 Hx58x BiSS C-mode + Sin/Cos WARNING The counting direction can be set also via BiSS interface. The parameter Code sequence in the Configuration register allows the operator to choose the options CW (clockwise direction) and CCW (counter-clockwise direction). When the counting direction is set to CW (default option) -Code sequence = CW-, if the Counting direction input has LOW logic level (0Vdc) the encoder will provide the increasing count when the encoder is turning clockwise (and the decreasing count when the encoder is turning counter-clockwise);...

  • Page 20 Hx58x BiSS C-mode + Sin/Cos Code sequence It allows to set whether the position information output by the encoder increases when the shaft rotates clockwise or counter-clockwise. Clockwise and counter-clockwise rotations are viewed from the shaft side. Please note that the counting direction affects the absolute position information, not the sine/cosine signals.
  • Page 21 Hx58x BiSS C-mode + Sin/Cos Number of revolutions [4E and 4F, rw] These registers set the number of revolutions (multiturn resolution). Possible values are less than or equal to the number of physical revolutions. We suggest always setting a value which is a power of 2 (1, 2, 4, …2048, 4096, …) in order to prevent the encoder from working within the limits of the so-called “red zone”...
