The SPiiPlusCMNT is a state of the art line of EtherCAT network multi-axis machine and motion controllers with two built-in universal drives.
It is specifically designed to extend the capabilities of the SPiiPlus line of control modules to address the needs of modern machinery for an
economical, scalable distributed control for motion centric applications. Its open architecture operates in conjunction with ACS’ line of EtherCAT
servo and step motor drives and I/Os modules, as well as with any certified EtherCAT module that complies with CAN over EtherCAT (CoE)
protocol, providing a comprehensive and cost effective control solution for demanding machinery. The SPiiPlusCMnt controls and generates
the motion profile for up to 32 axes.

The SPiiPlusCMNT is complemented by the SPiiPlus suite of software tools with built-in simulator. The tools are designed to minimize time to
market while providing the flexibility to meet the specific machine requirements throughout its life cycle. It provides easy setup, fast host and
embedded application development, and quick diagnostics, reducing efforts and costs.

The SPiiPlusCMNT is offered with the following current levels: 2.5/5, 5A/10A and 7.5A/15A (cont./peak). Optional Safe Torque Off (STO) module cuts the power to the
motor without removal of the power source to comply with SIL-3 and PLe safety levels. The module is powered by a single phase 85 to 230Vac
and by a separate 24Vdc control supply that keeps all low voltage signals alive during emergency conditions.



The module is fed by two power sources
A motor AC supply and a 24Vdc control supply
During emergency conditions there is no need
to remove the 24Vdc control supply
