5.2. Sections and cable specifications
Power cable specifications
- Maximum length 35m
- mobile or fixed installation depending on the applications
- max. conductor capacity 150pF/m
- use only stranded copper wire rated for 60/75°C
- Use only appropriate crimping tools to fix terminal lugs.
The cable used for the analogue reference must be a shielded twisted pair.
The cable used to connect the signals of the simulated encoder must consist of three twisted
pairs with a general shield.
Shielded cables are also recommended for digital inputs and outputs.
All cables must have a minimum section of 0.22 mm

Resolver cable
The cable must consist of three individually shielded and insulated twisted pairs protected by
a shield. The conductor-conductor capacity for the length used cannot exceed 10 nF and the
section cannot be less than 0.22 mm

. The maximum length is 35 m.
Connect of an EMI filter, if any
In case of direct connection to mains, the converter-filter connection cable length should not
be over 30cm.
In case of auto-transformer, the EMC filter can be connected upstream or downstream from
the auto-transformer. If it is connected upstream, it may be necessary to use a shielded cable
between the auto-transformer and the SLVD-N.
