Permissible motor cable lengths for SINAMICS S120 Booksize units with motor reactors
The motor reactors are designed for a pulse frequency of 4 kHz. Higher pulse frequencies are not permissible. The
maximum permissible output frequency when a motor reactor is used is 120 Hz. Motor reactors are approved for use
only in combination with "Vector" and "V/f control" modes.
When SINAMICS S120 units in Booksize format are used within the S120 Cabinet Modules range, please read the
supplementary information in the section "Options" of the chapter "Modular Cabinet Unit System SINAMICS S120
Cabinet Modules".

Chassis units

As standard (i.e. without motor reactors or motor filters (dv/dt filters, sine-wave filters) connected to the Motor Module
output), the following permissible cable lengths apply to SINAMICS S120 Motor Modules (Chassis and Cabinet
Modules).
Line supply voltage
380 V – 480 V 3AC
500 V – 690 V 3AC
Permissible motor cable lengths as standard for SINAMICS S120 Motor Modules in Chassis and Cabinet Modules format
When a motor reactor is used or two motor reactors are connected in series, the permissible cable lengths can be
increased. A second motor reactor is not a standard option for the S120 Cabinet Modules and may require an
additional cabinet (available on request).
The table below specifies the maximum motor cable lengths with motor reactor(s) that can be connected to S120
Motor Modules in Chassis and Cabinet Modules format. The values apply to the motor cable types recommended in
the tables and to other standard types of cable.
Line supply voltage
380 V – 480 V 3AC
500 V – 690 V 3AC
Maximum permissible motor cable lengths with 1 or 2 motor reactors for Motor Modules in SINAMICS S120 Chassis and
Cabinet Modules format
The motor reactors are only approved for use in combination with control types "Vector" and "V/f control".
The specified motor cable lengths always refer to the distance between the S120 Motor Module and motor along the
cable route. They allow for the fact that several cables must be routed in parallel for high-output drives. The
recommended and maximum connectable cross-sections as well as the permissible number of parallel motor cables
are unit-specific values. You must, therefore, refer to the technical specifications for the relevant Motor Modules.
For more information, see section "Motor reactors" of the chapter "Fundamental Principles and System Description".
