Control cable connection procedure R1…R9
WARNING! Obey the instructions in chapter Safety instructions on page 13. If
you ignore them, injury or death, or damage to the equipment can occur.
1. Stop the drive and do the steps in section Precautions before electrical work on
page 16 before you start the work.
2. Remove the front cover(s) if not already removed. See page 97 (R1…R4), page
105 (R5) or page 63 (R6…R9).
Analog signals
The figures for frames R1…R2 and R3 (page 128), R4 (page 129), R5 (page 130)
and R6…R9 (page 131) show an example of connecting a cable. Make the
connections according to the macro in use.
3. Cut an adequate hole into the rubber grommet and slide the grommet onto the
cable. Slide the cable through a hole in the cable entry and attach the grommet to
the hole.
4. Ground the outer shield of the cable 360 degrees under the grounding clamp.
Keep the cable unstripped as close to the terminals of the control board as
possible.
Frames R5…R9:
Secure the cables mechanically at the clamps below the control
board.
Ground also the pair-cable shields and grounding wire at the SCR terminal.
5. Route the cable as shown in the figures on pages 128 (R1…R2 and R3), 129
(R4), 130 (R5) or 131 (R6…R9).
6. Connect the conductors to the appropriate terminals of the control board and
tighten to 0.5…0.6 N·m (0.4 lbf·ft).
Digital signals
The figures for frames R1…R2 and R3 (page 128), R4 (page 129), R5 (page 130)
and R6…R9 (page 131) show an example of connecting a cable. Make the
connections according to the macro in use.
7. Cut an adequate hole into the rubber grommet and slide the grommet onto the
cable. Slide the cable through the hole in the cable entry and attach the grommet
to the hole.
8. Ground the outer shield of the cable 360 degrees under the grounding clamp.
Keep the cable unstripped as close to the terminals of the control board as
possible.
Frames R5…R9:
Secure the cables mechanically at the clamps below the control
board.
If you use double-shielded cables, ground also the pair-cable shields and
grounding wire at the SCR terminal.
