About This Product
Liberty MDrive Ethernet TCP/IP
About This Product
This manual is valid for the NEMA 17 (42mm) Liberty MDrive (LMD) Ethernet products with M12
circular connectors. This chapter lists the type codes for these products. The type code can be
used to identify whether the product is a standard product or a customized model.
Unit Overview
The LMD Ethernet TCP/IP consists of a stepper motor and integrated electronics. The product
integrates interfaces, drive and control electronics, and the power stage. There are three basic
control modes:
Closed Loop with hMT
:
Loop is closed by a 1000-line (4000 edge) magnetic encoder. May be
operated as:
•
hMT off:
standard encoder functions for position and stall monitoring
•
hMT on:
enhanced closed loop functions such as anti-stall and position maintenance.
Absolute with hMT
:
Closed loop with multi-turn absolute encoder, which will retain/update
position information upon loss/removal of power. Standard encoder and hMT features will
function as on a closed loop model. Refer to Appendix D on page 78 for details.
Open Loop
:
Standard open loop stepper control.
LMD Ethernet TCP/IP Products (LMDxE)
Included protocols on all Ethernet LMDxE devices include the Ethernet/IP, Profinet IO,
MODBUS/TCP, and MCode/TCP on a single device.
Setup parameters are set via the fieldbus interface using a software utility, available for

LMD Ethernet TCP/IP Protocols
Ethernet/IP
The LMD Ethernet may be used as a fully ODVA compliant Adapter class device on Ethernet/IP
networks.
MODBUS/TCP
The LMD Ethernet may be used in MODBUS/TCP networks, a standard open industrial
convention supported by a variety of machine components, such as programmable controllers,
drives and controls, I/O modules, and switches.
Profinet IO
The LMD Profinet may be used as an IO-DEVICE on Profinet networks with Siemens PLCs.
Motion commands, variables, and flags from the standard MCode control language are mapped
to input and output registers of the device. There are 38 output registers and 34 input registers.
MCode/TCP
The LMD Ethernet TCP/IP products are fully programmable motion control systems allowing
for complex program and I/O interaction. The following operating modes may be used
interchangeably:
