Improved slave axis performance with serial CANopen communications

Used In:

  • Any ECAM application using multiple slave axes in addition to the main axis

Using a virtual encoder on a CANopen network further improves System performance by transferring the Master axis position to the Slave using the network.

The G-MAS produces the encoder signal based on a pre-defined profile or according to the master encoder. When using a virtual encoder, no external hardware device is needed to produce axis position data — the G-MAS does this virtually through computation.

Also, there is no need for additional wiring from the master axis to each slave axis.

This slave-to-master axis positioning uses electronic cam (ECAM) technology, which brings significant indirect savings when transitioning from mechanical equipment to an electronic system.

Elmo’s distributed communication network solution makes it possible use the innate high efficiency of the G-MAS and each individual drive in the System.

Design Features

  • Synchronization and definition are performed by the G-MAS
  • The slave follows the encoder signal sent from G-MAS
  • All configuration is performed using the G-MAS
