Figure 139: Pin assignment: incremental encoder with a serial interface [X2B]
Pin Name Specification
1 MT+ Motor temperature sensor, normally closed contact, PTC,
NTC, KTY
9 U_SENS+ Sensor cables for the encoder supply. In case of long
cables, connect to US/GND at the motor end.

incremental encoder
7 #COS_Z0 / B-
15 SIN_Z0 / A+ SINE track signal (differential) of the high-resolution
incremental encoder

Avoiding EMC interferences
The outer cable shield must be connected to the housing of the angle encoder connector
with the greatest possible surface area (with low impedance).
