The SPiiPlusCMHV is a state of the art line of EtherCAT network multi-axis machine and motion controllers with one or 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 high voltage, high power, economical and 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, and provides a comprehensive and cost effective control solution for demanding machinery. The SPiiPlusCMHV controls and generates the motion profile for up to 32 axes at 1KHz, and up to 16 axes at 2KHz.
The SPiiPlusCMHV is complemented by the SPiiPlusNT 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 SPiiPlusCMHV is offered with the following current levels(cont./peak): 5A/10A , 10A/20A, 15A/30A, 20A/20A + 5A/10A with 230-480Vac, and 10A/30A, 15A/45A, 20A/60A with 230Vac.
Optional output current levels increase by 25% cont./peak within 230-400Vac supply range.
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 3 phase 230 to 480Vac and by a separate 24Vdc control supply that keeps all low voltage signals alive during emergency conditions.
