Maximize Motion System Accuracy and Throughput With the New CMxa and UDMxa!

ACS Motion Control proudly announces the release of two new products in the SPiiPlus series of EtherCAT-based motion controllers and motor drives. The CMxa and UDMxa are intended for applications with micron to nanometer resolution and demanding velocity control requirements — common in metrology, inspection, alignment, laser micromachining and other high-precision industrial applications.

These two new products are designed to be drop-in replacements for existing CMba/hp and UDMba/hp users, simplifying product migration. Both offer reduced jitter and noise while providing new optional safety features like SS1 and STO.

SPiiPlusCMxa

The CMxa is an EtherCAT master motion controller with integrated motor drives that leverage powerful servo control algorithms to maximize motion system performance. Its universal motor and encoder technology enable system designers to control most any type of motor or stage, providing extreme system design flexibility. The CMxa is supported by the SPiiPlus ADK Suite which contains many advanced servo tuning and application development tools.

The CMxa can be configured to control up to 64 total axes and includes 1, 2, or 3 built-in drives at up to 265Vac and 30A peak current output per axis. In addition to its integrated motor drives, system designers can control a large variety of distributed EtherCAT drives. The CMxa’s fixed servo sampling and update rate and high-speed distributed clock EtherCAT network provides the tightly synchronized real-time control needed for sophisticated multi-axis machine designs.

The CMxa is highly recommended for new machine designs and existing CMba and CMhp users.

Product features include:

  • Advanced PIV cascaded control loop.
  • Gantry MIMO control.
  • Optional ServoBoost control algorithm for dynamic disturbance compensation.
  • Optional MotionBoost for advanced motion profile generation.
  • Optional LearningBoost control algorithm for minimizing cyclic motion error.
  • Cascaded dual loop control.
  • Gain scheduling.
  • Disturbance rejection control.
  • Loop shaping filters.
  • 20kHz fixed servo sampling and update rate.
  • 5kHz EtherCAT max configurable cycle rate.
  • Configurable drive current output: 5/10A, 10/20A, 15/30A.
  • Optional built-in 4-axis pulse/direction interface.
  • 12bit or 16bit SinCos and analog input resolution.
  • 8/8 general purpose digital inputs/outputs.
  • 6/2 analog inputs/outputs.
  • 2/8 high-speed position event generation outputs (pulse/states).
  • Four registration mark inputs (MARK).
  • Optional STO and SS1 safety functionality.
  • Dimensions: 324 x 249 x 120 mm.
UDMxa

The UDMxa is a new EtherCAT drive controllable by any SPiiPlus series motion controller. The UDMxa features a powerful multi-processor architecture and includes universal motor and encoder technology. Advanced capabilities like ServoBoost, MIMO gantry control, high-speed position event generation and axis position capture enable high accuracy and throughput. The UDMxa is highly recommended for new machine designs and existing UDMba and UDMhp users.

Product features include:

  • Advanced PIV cascaded control loop.
  • Gantry MIMO control.
  • Optional ServoBoost control algorithm for dynamic disturbance compensation.
  • Cascaded dual feedback control.
  • Gain scheduling.
  • Disturbance rejection control.
  • Loop shaping filters.
  • 20kHz fixed servo sampling and update rate.
  • Configurable drive current output: 5/10A, 10/20A, 15/30A.
  • 12bit or 16bit SinCos and analog input resolution.
  • 8/8 general purpose inputs/outputs.
  • 6/2 analog inputs/outputs.
  • 2/8 high-speed position event generation outputs (pulse/states).
  • Four registration mark inputs (MARK).
  • Optional STO and SS1 safety functionality.
  • Dimensions: 324 x 249 x 120 mm.
