If you are looking for the part number for PanDrive Series stepper motors from Trinamic, you may see two suffixes, “CANOpen” & “TMCL” at the end of the part number.
These are the protocol name the motor uses.
CANOpen: CANopen is a communication protocol and device profile specification designed originally for embedded networking applications. Based on the CAN (Controller Area Network) protocol, CANopen offloads the system from CAN hardware-specific details, such as bit-timing and acceptance filtering.
TMCL: Trinamic Motion Control Language is a versatile protocol that can be used with a CAN, RS232, RS485, or USB interface.
Therefore, if the part number indicate the specific protocol, that mean the motor module is designated for that protocol.
Some base part numbers have two versions available, such as PD42-3-1241-CANOPEN and PD42-3-1241-TMCL.
