This involves a play-free electronic switching cam encoder (abbreviated to: NOCN) with two (At version 79 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. An absolute mulitturn encoder with CANopen interface, adjustable parameters and an electronic switching cam module is realized in the compact housing. A separate controller unit monitors the function of the cams.
The encoder's CANopen position signal and the switching outputs can be parameterised separately. The parameterisation (cam limits, resolution, measuring range a.s.o.) has to be verified to the NOCN via a checksum. This checksum can be calculated by a TWK program or the standard algorithm recommended by the CiA. After verification the device can be set operational.
Preset and resolution of the position signal also influence the cams which refer to the position signal. Parameterisation is carried out via the relevant CANopen objects in accordance with the encoder profile according to CiA, DS 406, revision 4.0.2.
The 79 mm housing styles can be supplied with an ATEX certificate to Zone 2/22 on request.
