3.6.1 Installing the axis interface SPC−AIF−...
Warning
Faults due to electromagnetic influences can cause fast
compensating movements of the axis. Observe the follow
ing installation instructions in order to avoid faults due to
electromagnetic influences.
· Connect the earth connection of the axis interface with
low impedance (short cable with large cross−sectional
area) to the earth potential.
· Only with measuring system type MLO−POT−...−LWG:
In order to earth the device, connect the earth strap (sup
plied with the measuring system) to the flat plug of the
measuring system and to the earth connection of the axis
interface (see Fig.A/9).
· Only with rotary module type DSMI−...:
In order to earth the device, connect the earth connection
of the DSMI−... and the earth connection of the axis inter
face with an earth strap or an earth cable (cross−sectional
area min. 2.5 mm
2
, length max. 0.5 m; see Fig.A/16).
· Do not place the axis interface cable, CP cable, measuring
system cable or proportional directional control valve
cable near or parallel to cables with high levels of inter
ference.
· Use only the original cables. Fasten the plugs with the aid
of the union nut in order to prevent unintentional loosen
ing, e.g. due to shock.
· Seal unused connections with the protective caps sup
plied. Only in this way can you comply with protection
class IP65.
Please note
Maximum two axis interfaces may be connected to an axis
interface string. Types for different measuring systems
may be mixed.
