NOTICE
Important wiring information
In order to meet EMC requirements, all cables must be shielded cables.
The cable shields of shielded twisted-pair cables should be connected to the shielding plate
or the hose clamp of the servo drive.
NOTICE
Drive damage caused by short-circuiting between the shielding wire and the unused pin on
the setpoint connector
The shielding wire may inadvertently be short-circuited to the unused pin on the to-be-
assembled setpoint connector. This can cause damage to the drive.
Exercise caution when connecting the shielding cable to the setpoint connector.
You can see the assembly method of encoder connector in Section "Assembly of cable
terminals on the drive side (Page 349)" for reference.
