Design of the cables
ƒ The cables used must comply with the approvals required for the location (e.g. UL).
ƒ It is imperative to comply with the regulations concerning minimum cross−sections
of PE conductors. The cross−section of the PE conductor must be at least as large as
the cross−section of the power connections.
ƒ The effectiveness of a shielded cable is reached by:
– Providing a good shield connection through large−surface shield contact.
– Using only braided shields with low shield resistance made of tin−plated or
nickel−plated copper braid.
– Using braided shields with an overlap rate > 70 % and an overlap angle of 90 °.
– Keeping unshielded cable ends as short as possible.
Use system cables or shielded cables for these connections:
ƒ Motor
ƒ Motor holding brake (shielding is required when being integrated into the motor
cable; connection to optional motor brake control)
ƒ Motor temperature monitoring
ƒ Analog signals (inputs and outputs)
ƒ System bus CAN
ƒ Resolver
ƒ Encoder
The following connections need not be shielded:
ƒ Mains
ƒ 24 V supply
ƒ Digital signals (inputs and outputs)
Tip!
Parameter setting and configuration can be carried out using the
L−force »Engineer«. For this purpose the Online Help and the Software Manual
for the standard device will guide you.
