New Ethernet protocol for integrated servo motors

Ready for Industry 4.0 and IIoT (Industrial IoT)
The JVL Sercos module is equipped with two Ethernet connectors and a built-in switch, enabling line and ring topology without any extra expensive hardware. The JVL Sercos module has several LEDs, enabling technicians and operators to get a quick status overview. There are also opto-isolated digital I/Os embedded in the module and enabling control of extra sensors, without external I/O modules. This minimises the number of devices on the net and reduces cable costs.

All connectors are rugged M12 connectors suitable for the rough conditions in industrial environments. Furthermore, all registers in the JVL MAC motor are accessible via the Sercos connection, thereby enabling complete control of motor configuration and motion. The JVL Sercos module is very easy to use and configure via a predefined setup, and commissioning is easy using the JVL MacTalk application software.

Sercos Industrial Ethernet
The JVL Sercos modules for MAC motor and ServoStep have all the important features from the Sercos specification. Automatic recognition of drives is supported by the FSPDrive and the Sercos Drive profiles (FSPDrive/PackProfile/SercosDrive). Synchronisation is supported enabling simultaneous operation of up to 511 motors. Hot plugging and redundancy is possible for exchanging motors without power off. Probe/capture is supported enabling use also in packaging machines.

JVL delivers SDDML files so the motor is recognised as FSPDrive by Bosch Rexroth. JVL’s Sercos motors are even found and recognised as SercosDrives without the presence of a SDDML file if you 'scan' from the Bosch Rexroth development environment (IndraWorks).

Practical Features

Is cabling is a hassle? Using the onboard Ethernet-switch you can daisy-chain cables from one Sercos motor to the next, enabling line and ring topology without any extra expensive hardware. On the motor-side, one of the big advantages of using integrated servo motors or stepper motors from JVL, is that you do not need to install a separate servo driver or controller in a control cabinet.

This gives you many subsequent advantages: Space savings in your control cabinet, saving of expensive motor and encoder cables, saving time (and money) for cabling, noise is minimised due to internal cabling, and installation errors between driver and motor are eliminated. In addition, service is much easier, since the motor and controller can be replaced as a single integrated unit. Hence, down-time is minimised and production is maximised.

Quite exclusive on the market, users can even change Ethernet protocol by updating the firmware using the MacTalk software.
