Notes on this data
igus says D1 and D2 are identical except for the housing.
Specify Motion is not affiliated with igus SE & Co. KG. igus and dryve D1 / D2 are used only to identify the product. Comparisons use published figures; always confirm against the current datasheet.
igus dryve D1 / D2 replacement and alternative options
Use these supply-network options as a starting point for an engineering check. We can also help source the original igus part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.

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 igus dryve D1 / D2
Send these with your enquiry and an engineer can confirm the right dryve D1 / D2 variant or an equivalent:
- 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
igus dryve D1 / D2: frequently asked questions
Can you help replace igus dryve D1 / D2 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 Motion Control Products options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the igus dryve D1 / D2?
igus motor controller for stepper, DC and EC/BLDC motors with CANopen or Modbus TCP, digital and analogue I/O and browser-based set-up; the D2 is rated to 21 A peak at 48 V. Published series figures include voltage 48 V, peak current 21 A. It is made by igus SE & Co. KG; Specify Motion can help source it or propose an equivalent.
Who makes the igus dryve D1 / D2?
The igus dryve D1 / D2 is made by igus (igus SE & Co. KG) and is listed here for engineers comparing options. Specify Motion is not affiliated with igus SE & Co. KG; brand names are used only to identify the product.
What is the voltage of the igus dryve D1 / D2?
The published series maximum voltage is 48 V. Individual models and sizes in the dryve D1 / D2 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 igus dryve D1 / D2?
We can assess suitable replacement options. On published figures, ADVANCED Motion Controls AxCent Analogue Servo Drives (AB, AZ, AV, B, AVB) and ADVANCED Motion Controls DigiFlex Performance Servo Drives (DP, DZ, DV) 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.
