Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.

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 CS3E Series
Send these with your enquiry and an engineer can confirm the right Leadshine CS3E Series 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 CS3E Series: frequently asked questions
Can you help replace Leadshine CS3E Series or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Leadshine CS3E Series?
Single-axis closed-loop EtherCAT stepper drive (CoE/CiA402) up to 8 A and 110 VDC, pitched as at least 40% cheaper than a networked servo. Published series figures include axes 1, current 8 A. It is available through our supply network, and our engineers can confirm the right variant for your application.
What model codes are in the Leadshine CS3E Series range?
The Leadshine CS3E Series range includes CS3E-D503, CS3E-D507, CS3E-D1008, CS3E-D503B, CS3E-D507B, CS3E-D503E, CS3E-D507E. 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.
Who makes the Leadshine CS3E Series?
The Leadshine CS3E Series is made by Leadshine (Leadshine Technology) available through our supply network. Send us your requirement for pricing, lead time, datasheets and CAD.
What is the axes of the Leadshine CS3E Series?
The published series maximum axes is 1. Individual models and sizes in the Leadshine CS3E Series 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.
Is there an alternative to the Leadshine CS3E Series?
We can assess suitable replacement options. On published figures, Kinco FD1 (FDxS) Series Low-Voltage DC Servo Drives (FD114S-FD164S) and Kinco JD2 Series AC Servo Drives are options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
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.
