The UDMPM is a line of EtherCAT universal single & dual axis economical drives for AC servo / DC Brushless, AC Induction, and DC brush motors.
The UDMPM operates as an EtherCAT node under any SPiiPlus EtherCAT master Controller including the PC based SPiiPlusSC
Soft Controller. It is designed to address cost sensitive applications requiring better move & settle, smooth velocity and stand still jitter performance with power of up to 1.6kW/3.2kW (continuous/peak) per axis.
The UDMPM is offered with two current levels: 5A/10A (cont./peak) and 7.5A/15A.
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 UDMPM 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.
