13bit SIN/COS Encoder converter - Interpolator
Overview
NL-NQ6D is an advanced interpolator for all kinds of SIN/COS 1Vpp encoders. This DIN-rail-mounting device converts the SIN/COS 1Vpp analog signal into quadrature digital output AB with TTL 5V level. Furthermore, it can convert the SIN/COS 1Vpp analog signal into digital output BiSS-C or SSI. This is necessary when the servo drive cannot directly use the SIN/COS signal as feedback.
Programming interface - Driver & Software
The interpolator can be programmed using the programming cable DE23500555-1M in combination with programming software.

Connectors
X1 connector is male d-sub 9, X2 connector is female d-sub 9, X3 connector is female d-sub 15.
Power supply
Using programming cable
When the programming cable is used, the power supply for the interpolator and the connected SIN/COS encoder can be provided by USB (in this case check that the current is sufficient for correct operation) or by an external 5V power supply connected on port X1.
Using Servo Drive
When connecting a servo drive BiSS interface, the 5V power can be provided by the feedback port of the servo drive, or by an external 5V power supply connected on port X1.
