16bit SIN/COS Encoder converter - Interpolator with Hall commutation signal outputs
Overview
NL-NQ8D is an advanced interpolator for all kind of encoders with SIN/COS 1Vpp. This device with DIN rail mounting converts the SIN/COS 1Vpp analog signal into Quadrature Digital output AB with TTL 5V level output. Furthermore, it can also convert the SIN/COS 1Vpp analog signal into digital output BiSS-C or SSI. Additional UVW output signals for commutation purpose are programmable from 1 to 32 polepairs.
This is necessary when the servo-drive is not able to use directly the SIN/COS signal as feedback.
Programming interface - Driver & Software
The interpolator can be programmed using programming cable DE23500555-1M in combination with programming software.

Using programming cable
When the programming calbe is used the power supply for Interpolator and the connected SIN/COS encoder can be provided
by USB (in this case check is the current will be enought for the correct ioperation) or with external 5V power supply connected
on the power X1.
Edit
Using Servo Drive
Connecting a servo drive BiSS interface, the 5V power can be porvided by the feedback port of the servo drive or
using external 5V power supply connected on port X1.
