6.3 WIRING AND GROUNDING
All the following cables must be shielded,
with 85% minimum shielding coverage:
- power motor cable (see Fig.6.2 and 6.3)
NOTES: if a power terminal board is used at motor
side, the shield must be RF connected to the
ground screw via the proper clip.
- connectors at motor side can have a threaded
clamp. Cable shield must be grounded in the same
way as in Fig.6.3.
- resolver cable (see Fig.2.3 and 6.3 motor
side)
FIG. 6.3 - GROUNDING OF SHIELD TO
CONNECTORS AT MOTOR SIDE
FIG. 6.2 - GROUNDING OF SHIELD TO
MOTOR CONNECTOR AT DRIVE SIDE
In case of Sub-D connector, cable shield
must be grounded to the metallic hood.
When there is not connector at drive side,
a kit with stand-off, screws and hose
clamps is provided.
The shield of the cable must be uncovered
from insulation coating and RF connected
to the stand-off through the hose clamp, as
in Fig.6.4.
- recovery resistor cable
- Reference, Enable and OK cable
- RS485 cable (flat cable between modules
excluded)
- simulated encoder cable (if applicable)
The shields of the cables must be
connected at both ends to the proper
housing via full circumferential bond to
metallic connectors or hose clamps.
