Cable selection depends on the cable construction, so refer to the
cable technical documentation to choose wire sizes
Some drives have cable limitations or recommendations; please refer
to the drive technical documentation for any further information.
Cable selection
At standstill, the current must be limited at 80% of the low speed
current I
o
and cable has to support peak current for a long period. So, if
the motor works at standstill, the current to select wire size is
2 x 0.8 Io
1,13 x I
