Connection of CanOpen bus cable
The bus cable shield can be grounded in three different ways:
a)
clamping the cable to the frequency converter frame
b)
to the frame of the frequency converter through an RC filter
c)
directly to the converter frame
Note: Normally, the option board has already been installed in slot E of the control board. It is not
necessary to detach the whole board for the grounding of the bus cable shield. Just detach the
terminal block.
4.4.1
Grounding by clamping the cable to the converter frame
This manner of grounding is the most effective and especially recommended when the distances
between the devices are relatively short (see 4.4.2.1).
In this manner of grounding, the position of jumper X1 is of no importance
Figure 4-3. Grounding by clamping the cable to the converter frame
1
Strip about 5 cm of the CanOpen cable in the same way as shown in Figure 4-4 but cut off the
grey cable shield.
Remember to do this for both bus cables (except for the last device).
2
Leave no more than 1 cm of the data cable outside the terminal block and strip the data cables at
about 0.5 cm to fit in the terminals. See Figures 4-5 and 4-6.
Note: Do this for both bus cabels
3
Insert the data cables of both CanOpen cables into terminals #2 and #4. See Figure 4-7.
4
Strip the CanOpen cable at such a distance from the terminal that you can fix it to the frame with
the grounding clamp. See Figure 4-4.Error! Reference source not found.
