Chapter 9 Additional requirements for the servo drives concerning the UL approval
on
page 113.
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.
8.7.4 Cable type and design [X2B]
We recommend using the encoder connection cables released for their product by the corresponding
manufacturer (Heidenhain, Sick-Stegmann, and so on). If the manufacturer does not recommend a
particular cable, we recommend the assembly of the encoder connection cables as described below.
For the angle encoder supply US and GND, we recommend
a minimum cross-section of 0,25 mm² for an angle encoder cable length up to 25 m
and
a minimum cross-section of 0,5 mm² for an angle encoder cable length up to 50 m.
