Components and Interfaces
LMD CANopen
Multifunction Interface
The multifunction interface operates at the following signal levels:
• +5 to +24V input signals are opto-isolated.
• 5.5 mA output signal is opto-isolated and current limited.
• 12-bit analog signal is not isolated.
The +5 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 high speed trip.
The reference voltage or current is applied to the analog input and may be used for a number
of programmatically defined operations.
Interface is accomplished via a 12-position M12 (male, A-coded) connector (P2).
CANopen Interface
The CANopen interface provides a connection to the CAN bus.
A computer may be connected to the interface via a Universal Serial Bus (USB) to CANopen
converter or the unit may be connected to a CANopen master device such as a Programmable
Logic Controller (PLC).
Commissioning is accomplished by using Layer Setting Services or by using the CANopen
Configuration Utility, which is part of the LMD Software Suite (LSS), available for download at
https://novantaims.com/dloads/
The CANopen interface is also used for firmware upgrades. Upgrades require the CANopen
Configuration Utility and the MD-CC502-000 or equivalent PEAK/Phytec CANopen converter.
The CAN bus is interfaced via a 5-pin M12 (male, A-coded) connector (P3).
Protective Earth (PE)
PE provides a means of grounding to the device chassis.
