Control cable connection procedure R0…R8
WARNING!
Obey the instructions in chapter Safety instructions . If you ignore them, injury or
death, or damage to the equipment can occur.
1. Stop the drive and perform the steps in section Electrical safety precautions (page 14)
before you start the work.
2. Remove the front cover(s) if not already removed. See section Connection procedure:
frames R0…R2 (page 72) , Connection procedure, frames R3...R4 (page 76) or Installing
the drive vertically, frames size R5…R8 (page 48) .
Analog signals
The figures for frames
R0...R2 (page 91) , R3...R5 (page 92) and R6...R8 (page 93)
show an example of connecting a cable. Make the connections according to the macro
in use.
3. Frames R4...R8: Cut an adequate hole into the rubber grommet and slide the grommet
onto the cable. Slide the cable through a hole in the lead-through plate 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…R8: 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 R0...R2 (page 91) and R6...R8 (page 93) .
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).

If you use double-shielded cables, ground also the pair-cable shields and grounding
wire at the SCR terminal.
9. Route the cable as shown in the figures R0...R2 (page 91) , R3...R5 (page 92) and
R6...R8 (page 93) .
10. Connect the conductors to the appropriate terminals of the control board and tighten to
0.5…0.6 N·m (0.4 lbf·ft).
11. Tie all control cables to the provided cable tie mounts.
