Cut an adequate hole into the rubber grommet and slide the grommet onto the cable.
Slide the cable through a hole in the bottom plate and attach the grommet to the
hole.
Route the cable as shown in the figures below.
Secure the cables inside the drive mechanically.
Ground the pair-cable shields and grounding wire at the grounding terminal (SCR) of
the control unit.
Connect the conductors to the appropriate terminals of the control unit (see page
31-32) and tighten to 0.5...0.6 N·m (0.4 lbf·ft).
Note:
Leave the other ends of the control cable shields unconnected or ground them
indirectly via a high-frequency capacitor with a few nanofarads, eg, 3.3 nF / 630 V.
The shield can also be grounded directly at both ends if they are in the same ground
line with no significant voltage drop between the end points.
Keep any signal wire pairs twisted as close to the terminals as possible. Twisting the
wire with its return wire reduces disturbances caused by inductive coupling.
