The popular and proven EtherCAT interface system is a fast, vendor-independent, Ethernet-based realtime open network for servo and I/O communications that works with CANopen over EtherCAT (CoE) servo drives and I/O devices.
With this system, RJ45 Ethernet cables are plugged directly into the Ethernet port on the PC, and servo drives are connected in a simple, single-line daisy-chain – no hardware is required. Up to 64 servo drives (plus additional I/O stations) can be integrated in one network.
The EtherCAT interface system is fast, with an interpolation rate as fast as 0.5 ms. Its simplified configuration and standard cabling, as well as the elimination of adapter cards, switches and hubs, make this a very economical system, both in terms of initial cost and in terms of maintenance.
EtherCAT around the world:
“Samsung Electronics Mecha Center selects EtherCAT for ultra high precision motion positioning.” -ETG Press Release (11/22/2005)
- Extremely fast — control of up to 64 servo axes with a cycle time as fast as 0.5 ms
- Simple wiring — single-line daisy chain without even a terminator
- Normal, off-the-shelf Ethernet cabling
- Supports commercially available Ethernet network interface cards.
- Easy to configure, diagnose and maintain
- Less expensive, due to simplified configuration, no plug in cards, no switches/hubs, and standard cabling
- Well proven technology
- Offers redundancy against cable or node failures (with second Ethernet port)
- Servo drives from different manufacturers can be connected in the same network
Hardware Connections in the EtherCAT Interface System
EtherCAT (Ethernet Control Automation Technology) is an industrial Ethernet fieldbus network that is real-time down to the I/O level — no delays in gateways, no underlying sub-systems. This interface system is based on 100 Mbps Ethernet.
EtherCAT Servo Drives
For the this interface system, servo drives must meet ETG’s CoE requirements. Servo drives meeting ETG’s CoE requirements are very likely, but are not guaranteed, to work with Soft Servo Systems’ motion controllers. The following is a list of EtherCAT servo drives that have been tested, and are known to be compatible with Soft Servo Systems’ EtherCAT interface system:
- Panasonic MINAS A5B ( Brochure)
- Yaskawa Sigma 7 EtherCAT
- Coplay Controls Digital Drives
- Kollmorgen AKD
- Omron G5
- Harmonic Drive LLC DEP and REL Series products
- Sanyo Denki LLC SANMOTION R ADVANCED
If your servo drives are not on this list, Soft Servo Systems would be happy to partner with you to verify the compatibility of your servo drives with Soft Servo Systems’ motion controllers, at no charge. Typically, this testing can be done within two weeks.

The DX-150P is a 4-axis pulse module that provides an interface to control up to 4 pulse type servos in a DXP network.
The DX-110A is a spindle and CNC interface module that provides an interface to control one spindle drive/analog servo, one hand-wheel, and 16 points of inputs and 16 points of outputs.
The IX-320 is an I/O module that provides 32 points of inputs and 32 points of outputs. Extremely fast, it can control the 32 servo axes with cycle time as fast as 0.5 m/s.
The IX-40A [FX-40] is a breakout box for EtherCAT platform.
