4.2 – CONNECTION OF THE SERIAL LINK RS-232
REMARK:
For PCs which are not equipped with the serial link RS232, RS232/USB converters must be used. But, since
RS232/USB converters are generally an office equipment, they are not meant to be used in an industrial
environment subjected to EMC disturbances. So, the serial link RS232 must be mandatorily shielded and
equipped with metal connectors at both ends for the 360° shield connection.
The RS232/USB converter must also be correctly shielded with a 360° shield connection at both ends.
4.3 – CONNECTION OF A BACKUP BATTERY
The consumption of the GD1 drive is 320 mA with 24 V
DC
. So, a 24 V / 30 A/h battery can keep the drive powered
during i.e. a long 3 days week-end. This backup method is very interesting for saving the machine initialization as
well as the axis position even when moving with the mains switched off.
4.4 – WIRING RECOMMENDATIONS
(according to EN61000.4-2-3-4-5-6 and EN61800-3-Part 3 standards. See diagram "Shield connection on the
connectors", section 4.2.2).
4.4.1 – G
ROUND CONNECTIONS AND GROUNDING
A shield has no effect if it is not connected:
♦
to a reference potential,
♦
by a connection as short as possible (a few centimetres; 10 centimetres is prohibited),
♦
by a "360°"shield connection. This means that the whole circumference of the shield sleeve must be
connected to the reference conduction via a metal collar.
The connectors used for the compliance with the EN61000.4 standard must be made of metal or metallized and
must allow the 360° shield connections.
CAUTION !
Each potential conducting element
must be shielded . Several potential conductors in the
same sleeve must be twisted and shielded .
