4.12 Configuring SoftMotion (CPX-CEC-M1-V3 only)
The Codesys software package SoftMotion is available as an extension for the controller CPX-CEC-M1-
V3. It allows coordinated multi-axis movements with a CPX terminal. Specific CPX-CEC-M1-V3 controller
features are produced in accordance with the CPX system properties.

4.12.2 Number of axes
The number of axes in SoftMotion is basically unlimited. The possible number of axes varies depending on
the complexity of the application. The key parameters for determining the number of axes are the bus
cycle time (guide value is 500 µs per servo controller at a transfer rate of 1 MB) and the actual cycle time
in the SoftMotion program. We recommend operating up to 8 axes on a CPX-CEC-M1-V3.
4.12.3 Cycle time/interpolation time
Different cycle times must be observed depending on the connected motor controller type ( Figure
Configuring a CANopen manager).
When using at least one motor controller of the type CMMS-ST, permanently set the sync cycle
time to 8 ms.
If only motor controllers of type CMMP-AS are used, differing settings (e.g. 4 ms) are also
possible.
