Typical applications
What a fieldbus stepper drive is
A fieldbus stepper drive receives motion commands over a network such as CANopen, Modbus RTU, EtherCAT or another industrial Ethernet protocol, rather than step and direction pulses. Commands set position, velocity and current targets, and the drive reports status, position and faults back to the controller. Many support standard device profiles such as CiA 402, so a PLC or motion controller can treat them like servo axes. Open-loop and closed-loop versions are common.
When engineers choose a fieldbus stepper drive
Choose a fieldbus stepper drive for machines with several stepper axes controlled by a PLC or motion controller, where wiring, diagnostics and parameter management matter. It replaces many pulse cables with one network. The trade-offs are configuration effort and network dependency: the drive needs network set-up and configuration files, and a network fault stops all axes. For a single simple axis, pulse control can be quicker to commission.
How to specify the Leadshine EM-CAN (EM522-CAN, EM556-CAN)
Send these with your enquiry and an engineer can confirm the right Leadshine EM-CAN (EM522-CAN, EM556-CAN) variant:
- Network protocol and device profile
- Supply voltage (V DC)
- Phase current (A)
- Open or closed loop
- I/O and homing functions
- Cycle time and synchronisation
- Configuration files and software
Common mistakes to avoid
- Choosing a protocol the controller does not support
- Not planning node addressing and network topology
- Overlooking cycle time for synchronised motion
- Missing configuration files for the controller
Leadshine EM-CAN (EM522-CAN, EM556-CAN): frequently asked questions

What model codes are in the Leadshine EM-CAN (EM522-CAN, EM556-CAN) range?
The Leadshine EM-CAN (EM522-CAN, EM556-CAN) range includes EM522-CAN, EM556-CAN. The table on this page lists each published model code with its key figures. Send us the code you use, or the one you need to replace, and our engineers will confirm availability, lead time or the closest equivalent.
What is the current of the Leadshine EM-CAN (EM522-CAN, EM556-CAN)?
The published series maximum current is 5.6 A. Individual models and sizes in the Leadshine EM-CAN (EM522-CAN, EM556-CAN) range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
What is CiA 402?
CiA 402 is a standard device profile for drives and motion control, originally for CANopen and also used on EtherCAT and other networks. It defines modes such as profile position, velocity and homing, and a standard state machine. Drives supporting it are easier to integrate with compatible controllers.
Is EtherCAT better than CANopen for stepper drives?
EtherCAT offers much higher bandwidth and precise synchronisation, which suits coordinated multi-axis motion. CANopen is simpler, cheaper and adequate for many point-to-point axes. Choose by controller support, number of axes, required cycle time and whether axes must be tightly synchronised.
