Overview
Example: Output reactors for Power Modules frame sizes FSA and FSB
Output reactors reduce the voltage loading on the motor wind-
ings. At the same time, the capacitive charge/discharge cur-
rents, which place an additional load on the power section when
long motor cables are used, are reduced.
Output reactors are only provided for the PM240 and PM250
Power Modules. An output reactor is not required for the PM260
Power Module due to its integrated sine-wave filter.
The maximum permissible output frequency is 150 Hz when an
output reactor is used – the pulse frequency must not exceed
4 kHz.
The output reactor must be installed as close as possible to the
Power Module.
Output reactors are approved for use only in conjunction with
“Vector” and “
V/f control” modes.
