Earthing the drives/displacement encoders...
Depending on the drive or displacement encoder used, these
must be earthed. See Tab.3/1.
Drive Description Earthing instructions
DGCI Linear drive with permanently
integrated position measuring
system.
·
Make a low−impedance connection (earthing
strap) between the flat pin of the position
measuring system and the earth potential!
Flat pin (DIN 46246−2, width: 4.8 mm)
DGP(L) Linear drive with external position
measuring system MLO−POT−...−TLF.
·
Mount the position measuring system so that it
is electrically isolated.
1)
DNCI Standard cylinder with integrated
position measuring system.
·
Make a low−impedance connection (short
cable with large cross section) between the
earth terminal on the cylinder and the earth
potential.
1)
A self−tapping screw for mounting an earth strap
is supplied with the displacement encoder.
DNC Standard cylinder with external
position measuring system
MLO−POT−...−LWG.
·
Make a low−impedance connection (earthing
strap supplied) between the flat pin of the
position measuring system and the earth
potential!
DNCM Standard cylinder with external
position measuring system already
mounted on delivery. No earthing is required.
DSMI Semi−rotary drive with integrated
position measuring system.
·
Make a low−impedance connection (earthing
strap) between the earth terminal of the DSMI
and the earth potential.
1)
Alternatively: Mount the drive on an earthed machine frame.
