IMS-MN-LMDE42C_A
Components and Interfaces
Liberty MDrive Ethernet TCP/IP
Components
Motor
The motor is a two phase brushless stepper motor. The step angle of the motor is 1.8°.
Electronics Housing
The electronics system is comprised of control electronics and power stage.
The drive system is controlled by streaming commands via the service interface, embedded
programming, or by pulse and direction input signals.
Interfaces
DC Power Supply Voltage
The supply voltage
VDC
supplies the control electronics and the power stage of the drive,
including a +12V to +24V Aux-Power input to supply power to logic circuits in the event of main
supply interruptions.
The ground connections of all interfaces are galvanically isolated with the exception of the
analog input. For more information on ground connections and protection against reverse
polarity, see “Ground (Earth) Design” on page 41.
Multifunction I/O Interface
The multifunction I/O interface operates at the following signal levels:
• +5V to +24V input signals (opto-isolated)
• 5.5 mA output signal (opto-isolated)
NOTE:
For information on how to increase the Output current, refer to “Output 3”
Knowledge Based Solutions, available from:

• 12-bit analog signal (not isolated)
The +5V to +24V input signals are programmable as general purpose or to predefined
functions.
The output is a 5.5 mA signal output, which can be defined as a high speed trip.
The reference voltage or current that is applied to the analog input can be used for a number of
programmatically defined operations.
Ethernet Interface
The service interface provides a connection to an Ethernet network.
Commissioning software is used to configure the device IP address and subnet mask. The
Ethernet Interface is available via the LSS Ethernet firmware upgrades are performed through
the Ethernet Interface.
NOTE:
Additional setup will be required for initial setup on devices with CyberSecurity enabled.
Devices with CyberSecurity enabled will have a “CSE” marking on the packaging and product
label. For additional information on CyberSecurity, refer to:

Protective Earth
Protective earth provides a means of grounding to the device chassis.
