Danger!
Danger to life through improper installation
Improper installation of the safety engineering systems can cause
anuncontrolled starting action of the drives.
Possible consequences:
ƒ Death or severe injuries
Protective measures:
Total cable length between X82 and its connected components (e.g. sensors,
devices, ...) > 3 m:
ƒ A shielded laying system must be used for the cable between X82 and its
connected components:
– The shield must at least cover the shield connection at the installation
backplane.
– The shield should also cover the connected component if possible.
ƒ Unshielded wiring is permissible from hardware version 1A.
Total cable length between X82 and its connected components (e.g. sensors,
devices, ...) < 3 m:
ƒ Unshielded wiring is permissible.
Residual hazards
In case of a short−circuit of two power transistors a residual movement of the motor of up
to 180 °/number of pole pairs may occur! (Example: 4−pole motor
Þ residual movement
max. 180 °/2 = 90 °)
This residual movement must be considered in the risk analysis, e.g. safe torque off for main
spindle drives.
