Schneider Electric NEMA 23 Lexium MDrive Pulse/Direction Input

NEMA size 23 Pulse/Direction Input

The Lexium MDrive Pulse/direction input is an integrated motor + driver with numerous enhanced features for a complete motion control solution.



Communications interface

The LMDxP uses an isolated RS-422/485 communication interface with selectable BAUD rate ranging from 4.8 to 115 kilobits per second via a standard 9-pin D-subminiature connector. An optional USB to RS-422/485 Comm converter with cable is available and is compatible with all 32 and 64 bit operating systems.



Power and I/O

DC power and the I/O are interfaced via robust locking connectors: a 2-pin screw lock connector for power, and a pair of 7-pin spring-clamp terminal blocks with side-locking tabs for I/O. The isolated I/O bank consists of +5 to +24 VDC inputs for step, direction and bridge enable/disable, one (1) 5.5 mA Attention output, a 12-bit analog input and six TTL level differential encoder outputs, which are not isolated. The clock and direction inputs may be programmable to multiple clock types in software, either pulse/direction, quadrature or CW/CCW.



Selectable modes of operation

Unlike traditional pulse/direction devices, the Lexium MDrive Pulse/direction input may be configured to operate in the following modes of operation:


  • Pulse/direction mode: The LMDxP will perform motion in response to step clock and direction signals on the inputs.
  • Speed control mode: The LMDxP will intelligently control the axis velocity based upon parameter configuration in software and a signal applied to the analog input.
  • Torque control mode (Closed Loop Only!): The LMDCP will intelligently control the shaft torque based upon parameter configuration in software and a signal applied to the analog input.
  • Constant velocity mode: The LMDxP will intelligently control the axis velocity based upon parameter configuration in software and the value of a slew at velocity command sent over the RS-422/485 interface.


Software

The Lexium MDrive Pulse/direction uses the powerful, yet easy to use Pulse/direction Configuration Utility which is part of the Lexium MDrive Software Suite. The Pulse/direction Configuration Utility is used to set all the available parameters of the LMDxP and can be used in either basic or advanced modes. Basic, for standard pulse/direction functionality with basic parameters, or Advanced, for configuring hMTecnology and advanced operating modes.
