20-line ribbon cable
(PWM signals)
April 2007
The 20-line ribbon cable connects the PWM outputs of the control with the
corresponding UM 1xx(D) power modules. One 20-line ribbon cable is required
for each axis or spindle.
Ribbon cable length
100 mm
200 mm
300 mm
400 mm
500 mm
600 mm
700 mm
How to select the cable length:
See the table for distance a of the PWM input on the power module.
Add the widths b of all modules (including UP 110 and UV 105) between the
corresponding power module and the LE 4xx M or CC 42x.
Then add the distance c
Select the next-longer cable length, unless there is an exact match.
