INFORMATION
The Motor temperature sensor can either be connected to X2A or X2B. It is not
possible to connect multiple sensors.
INFORMATION
In addition, a low-impedance connection of the outer cable shield to the housing of the
servo drive has to be established. Therefore, the outer cable shield of the angle
encoder cable must be connected to the housing of the angle encoder connector.

The outer shield is always connected to PE (connector housing) on the servo drive.
The three inner shields are connected on one side of the servo drive ARS 2300 FS to Pin 3 of [X2A].
