Configuration
Permissible cable lengths
In the case of long cables between the converter and the motor,
reflection phenomena lead to overvoltages and recharging
currents on the cables and at the motor terminals and, in turn, to
a higher level of stress on the motor insulation. The motor insula-
tion is additionally subject to stress as a result of the voltage
rates of rise (voltage gradients).
The increased stress on the cables and motor as a result of
reflection phenomena in the case of long cables can be signifi-
cantly reduced using a sine-wave filter at the converter output
(option
Y15
).
The recharging currents in the cables and in the motor can be
significantly reduced by using reactors at the converter output
(option
L08
).
Maximum cable lengths without and with output reactor
Data regarding cable lengths when using option
L08
(output reactor) can be obtained for specific systems from
your local Siemens sales contact.
