SVTS A Series - Slip Ring with Optic Fibre

Martedì, 05 Febbraio 2019

Slip Ring con fibra ottica per applicazioni outdoor
Here is an example of a Servotecnica solution for carrying power and high data-rate signals on board a cable reel.
Since this installation is on an off-shore platform, a solution resistant to a saline environment had to be provided.

Technical data:
  • 2 x 2.5 A circuits
  • 400VAC IP65
  • Max speed: 2000 rpm
  • -40 °C +80 °C
  • Optic fibre: 1 ch single mode Rotary Joint

MAC® and ServoStep: EtherCAT with CiA drive profile

Merocledì, 30 Gennaio 2019

MAC e ServoStep - EtherCAT con profilo drive CiA
EtherCAT (Ethernet) con profilo drive CiA402 per motore MAC® e ServoStep

Ready for Industry 4.0 and IIoT (Industrial IoT)

The JVL EtherCAT module is equipped with two Ethernet connectors and a built-in switch, enabling line, star, tree and ring topology without any extra expensive hardware. The JVL EtherCAT 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, enabling control of extra sensors etc. without external I/O modules. This minimizes 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 EtherCAT connection, thereby enabling complete control of motor configuration and motion.
The JVL EtherCAT module is very easy to use and configure via a predefined setup, and commissioning is easy using the JVL MacTalk application software. 

EtherCAT Industrial Ethernet

The EtherCAT module with CiA402 drive profile for JVL servo and stepper motors support the synchronized position (CSP) and synchronized velocity (CSV) modes as well as the old modes profile position, profile velocity and many homing methods. The synchronized cycle times for MIS Integrated Stepper can be 1, 2, 3 and 4mS. MAC Integrated Servomotor have 1 and 2mS cycle times. Both have a maximum of ±1µs of jitter.
The JVL EtherCAT equipped motors are plug and play compatible with Beckhoff PLC’s, and also compatible with other manufacturers of EtherCAT masters such as Omron, Lenze, Trio and others.

Practical Features

Cabling is a hassle? Using the onboard Ethernet-switch you can daisy-chain cables from one EtherCAT 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 minimized 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, downtime is minimized and production is maximized. 
Quite uniquely on the market, users can even change Ethernet protocol by updating the firmware using the MacTalk software. 


MIS NEMA 17-43 certificato TÜV STO SIL3 / PLe

Safety Torque Off per Motore Passo Passo approvato dal TUV - JVL
The STO Function can be used for disabling the energy to the motor. The motor will thereby be set in a state where it produces no torque.
The STO function has its own input connector mounted at the front of the motor.

It is a two-input system and it is required that both inputs are activated (applied with a voltage) before the motor is energized and can operate normally.

The STO is available for all ServoStep products.
