SINAMICS S120 Gearing with DCC

  • Entry
  • Associated product(s)
Gearing permits relative motion between a leading and following axis with the correct angle. This replaces mechanical eccentric gears.

Note: For this application example, there is already a newer version available 109757232


Task
In synchronous operation, the axis is externally controlled as following axis. The position setpoint is derived from a leading axis (master value source). In the synchronous operation mode, many axes can be coupled, which are either all controlled from the same leading axis or in groups of various leading axes.

Solution
This application solves the task by means of the blocks from the GMC library. The GMC library is based on SINAMICS DCB Extension and is an extension for the existing DCC standard library. With the new motion control blocks, application function can be realized drive based in SINAMICS S120.

 

The gearing application application includes the following functions:

  • Real leading axis
  • Virtual leading axis
  • Catching up/stopping
  • Engaging/disengaging operation
  • Electronic gear
  • Synchronization to master value
  • Absolute and relative offset input
  • Print mark correction on leading and following axis side
  • Flying homing for following axis and real leading axis
  • Homing for following axis and real leading axis
  • Positioning for the real and virtual leading axis
  • Deadtime compensation
  • Following error monitoring
