Easy Motion Control offers the following basic functions for positioning:

• Move absolute:
  The axis moves to the specified position. With rotary axes, the target can be approached in a positive or negative direction or on the shortest possible path.
• Move relative:
  The axis moves by the specified distance in a positive or negative direction.
• Reference point approach, reference setting:
  Synchronizes the measuring system with the mechanical system.
• Gearing:
  Axis moves to a different axis in gearing.
• Jog:
  The axis moves for as long as the control bit for one direction is present.
• Stop:
  Stops the motion and brings the axis to a standstill.
• Simulation:
  A program can be tested in the simulation even if a real axis is not present and no actual values can be read in.
• Override:
  A factor between 0 und 100% can be applied to the speed of the motion at any time. Acceleration and deceleration are not influenced by this.
• Override travel motion:
  Any motion block can override any other motion block. The current motion is transferred to the new motion with the specified acceleration or deceleration.

Further function blocks must be additionally integrated into the user program, such as the position controller and input/output drivers.

The Easy Motion Control block is called in a time-driven level, e.g. a cyclic interrupt.

The function blocks of Easy Motion Control have been developed in accordance with the technical specification of PLCopen, "Function Blocks for Motion Control", Part 1, V1.0.

New functions in V2.1

• PROFINET:
  The Encoder SM 338 (FB 25) and Encoder FM 350 (FB 27) blocks now use the SFB 52 instead of the SFC 59. This additionally allows distributed use with PROFINET.
• The output driver for MICROMASTER 4 has been expanded, and now supports the motor holding brake function.
