13.5 Connector: resolvers/analogue Hall
encoders [X2A]
Two different encoder types can be connected to the 9-pin D-Sub connector:
l Resolvers
l Analogue Hall generators with tracks that are offset by 90° (sine/cosine)
Diverging from the analogue evaluation via the X2B interface, this input has a higher
resolution and it is possible to read in higher amplitudes.
Configuration on the device [X2A]
D-SUB connector, 9-pin type, female
Mating connector [X2A]
l D-SUB connector, 9-pin type, male
l Housing for a 9-pin D-SUB connector with locking screws of type 4/40 UNC
Pin assignment [X2A]
Figure 136: Pin assignment: resolver connector [X2A]
l The outer shield is always connected to PE (connector housing) on the servo drive
side.
l The three inner shields are connected to PIN 3 of X2A on one side of the servo
drive.
