Siemens Simatic S7-1500 - Properties of the Digital On-Board I;O

Integrated technology
Function Description Additional information
Motion control The CPU of the SIMATIC Drive Controller supports the S7‑1500 Motion
Control functions via the technology objects: speed axis, positioning
axis, synchronous axis, external encoder, cam, cam track and measur
ing input.
• Speed-controlled axis for controlling a drive with speed specifica
tion
• Positioning axis for position-controlled positioning of a drive
• Synchronous axis for interconnecting with a leading value. The
axis follows the position of the leading axis in synchronous opera
tion.
• External encoder for detecting the actual position of an encoder
and its use as a leading value for synchronous operation
• Cam, cam track for position-dependent generation of switching
signals
• Measuring input for fast, accurate and event-dependent sensing
of actual positions
You program the technology objects with Motion Control instructions
according to PLCopen.
Extended motion con
trol functions
The SIMATIC Drive Controller contains a SIMATIC S7-1500 technology
CPU. The technology CPU provides extended motion control func
tions:
• Extended synchronous operation functions
– Synchronization with specification of the synchronous posi
tion
– Actual value coupling
– Offset of leading value on following axis
– Camming
– Velocity gearing
• Up to four encoders or measuring systems as actual position for
position control
• Control of kinematics, such as
– Cartesian portals
– Roller pickers
– Delta pickers
– SCARA
• Cross-PLC synchronous operation: Coupling between leading axis
or external encoder and following axis via PROFINET IO with IRT
