Profile / Cyclic Synchronous Modes

In a profile mode of operation, the trajectory is limited by the drive. Profile modes use the command limiter values to limit the maximum command rate. Cyclic Synchronous modes give responsibility of trajectory control to the host. The drive interpolates between command points, defining the rate by dividing the change in command by the interpolation time period.



  • A large command step in Profile modes spreads the demand over a period of time to stay equal to or below the maximum defined rate
  • The host sends fewer commands in Cyclic modes without adversely affecting motion since the drive responds smoothly to each step in command
  • Profile / Cyclic modes yield smooth performance with reduced bus traffic
