L04
Infeed module one size smaller
With this option, the infeed (Active Line Module/Active
Interface Module) is rated one power level lower than the
Motor Module (inverter).
This option is suitable for the following applications,
for example:
• When the Motor Module is operated at pulse frequencies
greater than the rated pulse frequency, which means that
the output power is reduced (current derating as a function
of the pulse frequency).
• If the rated power is required in regenerative mode and the
system losses are covered by the Motor Module.
• With motors that have a higher efficiency and/or a lower
power factor compared to typical standard induction motors.
• The application requires high current of the Motor Module
only at lower speeds (maximum power demand than the
maximum power rating of the unit), e.g. drives with a high
breakaway torque.
When using option
L04
, the following restrictions apply:
• The rated output current of the Motor Module is only
available as long as the infeed (Active Line Module) is
not loaded with the rated power.
• In the event of line undervoltage, the output power is
reduced in proportion to the line voltage.
• The unit should be operated at unity line power factor
(this corresponds to the factory default setting) to provide
only active power. (no reactive power compensation).
Option
L04
is available only for the following units:
L08
Motor reactor
Motor reactors reduce the voltage load on the motor windings
by reducing the voltage gradients (dV/dt) generated by the
drive at the motor terminals. (Note that a motor reactor does
not increase the maximum motor cable length for SINAMICS
S150 – refer to engineering information).
L10
Output dV/dt-Filter with VPL (Voltage Peak Limiter)
The dV/dt filter plus VPL allows the connection of non-
inverter duty motors to the SINAMICS S150 drive.
For motors insulated per NEMA MG1, part 30 (voltage peaks
<1,000 V and dV/dt <500 V/µs) the maximum allowable
motor cable length is as follows. Note that longer cable
lengths of up to 450 m are possible, but voltage peaks may
exceed 1,000 V. Please refer to engineering information for
additional details.

The dV/dt filter plus VPL consists of two components: the
dV/dt reactor and the VPL (Voltage Peak Limiter), which limits
voltage peaks and returns the energy to the DC link. It is
housed in an add-on options cabinet. Option L10 cannot be
combined with option M78 (Motor side top cable exit).
L17
Feeder for external auxiliaries (line volts) 3ph. AC
An outgoing circuit fused at max. 10 A for external auxiliary
equipment (for example, a motor blower). The voltage is
tapped at the converter input and, therefore, has the same
level as the supply voltage. The circuit includes a motor
circuit protector (MCP) and a contactor (120 V coil) that
can be controlled internally by the drive or externally.
L40
Filter (AIM) monitoring
The very low line harmonics of the Active Infeed can only
be guaranteed if the clean power filter functions correctly.
Option
L40
is recommended especially for weak and
sensitive line supplies where the harmonic quality must be
guaranteed, and where a reduction of filter performance is
not acceptable. This option monitors the filter characteristics
and reliably identifies any changes. The following
characteristics are monitored:
• Filter capacitance: The capacitance of the filter is calculated
using the current and voltage. The calculated value is
compared with the installed capacitance. An alarm is
issued if a capacitor fails.
• Short-circuit: A short-circuit in the filter is identified by
monitoring the current and voltage. The current is
monitored against a maximum value and the voltage
against a minimum value. An OFF 2 trip command (coast
to stop) is issued to the main circuit breaker if a limit value
is exceeded.
L50
Enclosure light with power outlet 120 V, 1 ph AC, 5 A
One universal light with an integrated service socket (3 pin
US style) is installed in the line connection cabinet of the
drive as well as in the add-on options cabinet (if applicable).
The light is switched manually. This option requires an
external power source.
