Electronic digital switching cam encoder model NOCN Description General functional principle Switching outputs (cams) This involves a play-free electronic switching cam encoder (abbreviated to: NOCN) with a maximum of four galvanically separated switching outputs (cams), which can be set by the customer and which are activated or deactivated depending on the relevant position of the drive shaft. A parameterisable multiturn absolute encoder with CANopen interface plus the switching cam encoder printed circuit board with separate controller are integrated into the compact housing. The...

Find details on page 11 Order code number, remarks V1: This version provides complete galvanic separation. Power supply and CAN_GND is galvanically separated. The housing and the screening of the cable is galvanically separated as well. The screening of the cable comes to the housing of the NOCN via the housing of the mating plug. V2: This version provides partly galvanic separation. Power supply and CAN_GND are not galvanically separated. The housing and the screening of the cable are galvanically separated from power supply and CAN_GND. The screening of the cable comes to the housing of...

Switching outputs Function The function of the switching outputs (cams) is implemented by means of relays and PhotoMOS semiconductors. The relays provide changeover contacts and the PhotoMOS semiconductors provide normally open contacts (NO). All switching outputs are galvanically separated in terms of operating voltage and the CANopen bus. The information regarding when which relay is to pick up and drop off again is made available to the relay control system by the internal controller. If receives the shaft position data from the NOCN's absolute encoder. The precise position of the...

Electronic digital switching cam encoder model NOCN Switching outputs Parameterisation of the switching outputs (cams) Each of the switching outputs can be parameterised via the CANopen bus. To achieve this, a range of objects is assigned to each switching output in the CANopen profile according to CiA, DS 406 revision 4.01. These objects enable each switching output to be set individually: Object 6310: Low limit Cam 1 > Cam 1 switches on in this position (relay picks up) Object 6320: High limit Cam 1 > Cam 1 switches off in this position (relay drops off) Object 6330: Hysteresis Cam 1 >...
