CANopen for the ServoStep™
integrated stepper motors

 
PRESS release: May 2021


Birkerød, Denmark - JVL A/S, one of the world’s leading producers in the field of integrated servo and stepper motors, is announcing an improved implementation of the CANopen protocol for slave operation.
 
CANopen Key Features
All motor functions are available in CANopen through gateway objects with selectable data rate up to 1 Mbit/s. Monitoring and debugging features with JVL’s MacTalk® software. CANopen over MacTalk® also possible. Easy configuration from PLC through JVL CAN explorer.
  • CANopen – DS 301 and DSP 402 support
  • CANopen – DSP402 in Profile Position & Velocity mode, Homing (Zero Search) mode and Interpolated Position mode
  • Read and write access to all 512 motor registers
  • Up to 24 programmable TX PDO and 24 programmable RX PDO
  • ≥ 5 kHz asynchronous PDO update with default mapping
  • ≤ 2 ms interpolation synchronization
  • EDS Electronic data sheet
  • TwinCAT 3 compatible: TwinCAT 3 sample project can be downloaded
  • CANopen as NC axis in TwinCAT - step by step TwinCAT 3 setup guide
Below is a screen example from the "JVL CAN explorer” software:

 
Other CAN bus Features
 
JVL has developed another smart feature for ServoStep™ motors running CAN bus: the "Slave-follower-mode”.
With this mode you don’t need an external master – you simply use one of the motors as Master and the other motors as Slaves. Up to 8 motors can run synchronized. Contact JVL to learn more about this Master-Slave mode. NB! This mode doesn’t follow the CANopen standard.
 
 
ServoStep™ Motors
 
JVL’s integrated stepper motors have everything built-in: high torque motor, incremental or absolute multiturn encoder, driver electronics, controller electronics with ePLC™ and RS485 communications bus. Also included are 8 I/O points which can be individually configured as digital input, digital output or analogue input.
The CANopen circuit include transceiver hardware and two M12 connectors for easy daisy-chaining of cables from motor to motor.
 

 
Motor specifications
  • Wide size range from NEMA 17 to NEMA 43 with Holding Torques of 0.36 - 25 Nm
  • Closed-loop control – no loss of steps or position
  • Energy efficient due to Automatic current control
  • Built-in ePLC™ with 8 DIO, 24V or 0-5V (12bit) analog input with advanced filtering
  • Ultra-high resolution: 409600 step/rev
  • Speed-resolution down to ±0.01 RPM
  • Change speed or torque or other parameters ”on-the-fly” (while driving)
  • Top or rear-end mounted M12 connectors or Option M23 hybrid connector
  • Instead of CANopen there are options for all major industrial Ethernet protocols
  • Option: Absolute multiturn encoder
  • Option: Double shaft and electro-mechanical brake
  • Option: STO (safe torque off, SIL3)
