Power cable between
motor and Motor Module I
Cable between the Braking Module and braking resistor
For longer lengths, the user must connect a suitable protective circuit in order to provide overvoltage protection (refer to
1)
the chapter "Overvoltage protection" under "24 V DC supply")
To comply with EMC limit values, shielded cables (preferably MOTION CONNECT cables) must be used.
2)
Restrictions regarding the total cable length and the secondary conditions required to comply with the corresponding
3)
radio interference suppression category are listed in Chapter "Possible line reactor and line filter combinations".
The total lengths specified for power cables in the drive line-up include motor cables, DC link cables, and the line feeder
4)
cable, line filter to the Line Module.
Note
Total cable lengths
also referred to Basic Line filter for Active Line Modules (Page 62) as well as Possible line
reactor and line filter combinations (Page 136).
