Description of options

SMC20 Sensor Module Cabinet-Mounted
The SMC20 Sensor Module Cabinet-Mounted connects
to an incremental encoder to simultaneously sense the
speed and the rotor position angle of a motor, and make
this information available to the regulator via the
DRIVE-CLiQ interface.
The following encoder signals can be evaluated:
•
Incremental encoder sin/cos 1 VPP
• EnDat absolute encoder
•
SSI encoder with incremental signals sin/cos 1 VPP
(firmware version 2.4 and later)
The motor temperature can also be detected using
KTY84-130 or PTC thermistors.
Description of the SMC20 Sensor Module Cabinet-Mounted –
Chapter 3.
K50
SMC30 sensor module for speed feedback
The SMC30 encoder module is used to connect a speed
feedback encoder to the drive. Rotary pulse encoder signals
are converted for evaluation via the DRIVE-CLiQ interface of
the controller.
The following encoders are supported by the SMC30:
• TTL encoders
• HTL encoders
The motor temperature can also be detected using a
KTY84-130 sensor or PTC thermistors. Description of the
SMC30 Sensor Module Cabinet-Mounted – Chapter 3.
K51
VSM10 voltage sensing module
The VSM10 Voltage Sensing Module reads the voltage
waveform at the drive output to allow implementation of
the following functions:
• Flying restart of a permanent-magnet synchronous motor
without encoder.
• Quick flying restart of large induction motors: The voltage
sensing function eliminates the delay incurred by
demagnetization of the motor.

Chapter 3.
K52
Additional SMC30 Sensor Module
This option code is to add a second SMC30 sensor module
(in addition to one specified by option K50). Two SMC30
with associated encoders may be required for Safety
Extended functions.
K82
Terminal interface for controlling the “Safe Torque Off”
and “Safe Stop 1” safety functions
This terminal interface offers a wide voltage range (24 V to
240 V DC or AC) for easy integration of the following basic
Safety Integrated functions into the plant controls:
• Safe Torque Off (STO)
• Safe Stop 1 (SS1) (time-controlled)
The components inside the drive (Control Unit and Power
Module, from the terminals on these devices) are certified
in combination with firmware versions to satisfy the
requirements of the following standards. With option K82
the enclosed drive unit also meets the requirements of:
• Machinery Directive 98/37/EC
• IEC 60204-1
• ISO 13849-1 Category 3, for Performance Level (PL) d
• IEC 61508 SIL 2
These Safety Integrated functions of SINAMICS S150 are
generally certified by independent institutes. An up-to-date
list of certificates is available on request from your local
Siemens office.
K87
TM54F Terminal Module
The TM54F Terminal Module provides fail safe digital inputs
and outputs for hardwired control of the Safety Integrated
extended functions (as opposed to control via bus
communications with PROFIsafe).
Safety Integrated extended functions require a safety license
(option
K01
).
The TM54F must be connected directly to the Control Unit
via DRIVE-CLiQ.
Note: It is not permissible to connect Motor Modules and
Line Modules to a TM54F. The TM54F has 4 fail safe digital
outputs and 10 fail safe digital inputs. A fail-safe digital
output consists of one 24 V DC switching output, an
output switching to ground and one digital input to check
the switching state. A fail-safe digital input consists of two
digital inputs.
K88
Safe Brake Adapter SBA, 230 V AC
Safe Brake Control (SBC) is a basic safety function that is
used in safety-relevant applications, for example in presses
or rolling mills. In the no-current state, the brake is applied
to the drive motor shaft using spring force. The brake is
released when current flows in it (low active).
The Safe Brake Adapter 230 V AC is factory installed in the
drive. A source of power is connected to terminal -X12 on
the Safe Brake Adapter. For control, a connection is
established between the Safe Brake Adapter and the Control
Interface Module in the factory using a wire harness.
On the plant side, to control the brake, a connection must be
made between terminal -X14 on the Safe Brake Adapter and
the brake.
Note: The safe brake adapter is not yet UL listed. Option
K88 cannot be included in a UL listed drive.
