● Motor cable length 50 m ... 100 m: set the pulse frequency to 2kHz.
● Motor cable length > 100 m: the permissible base load output current decreases by 1 %
for each additional 10 m cable length.
Longer motor cables for Power Modules FSA ... FSC
For EMC Category C2, second environment, cable lengths of up to 150 m are permissible, if
you use an unfiltered Power Module with an external Class B line filter and an output reactor.

Motor connection

Star and delta connection
Siemens motors have a diagram inside the
terminal box showing both connection meth-
ods:
• Star connection (Y)
• Delta connection (Δ)
The motor rating plate provides data about
the correct connection.
Connecting the motor
