Information About 1398-DDM-075
The 1398-DDM-075 is part of the Ultra 200 servo drive family, offering microprocessor-based regulation of torque, speed, and position for demanding motion control systems. It operates from 100–240 VAC at 47–63 Hz, with an auxiliary AC input providing additional isolation for control electronics. The drive provides continuous output currents of 15 A for single-phase and 35 A for three-phase input, supporting continuous power output up to 7.5 kW in three-phase operation. Peak power output reaches 14 kW (single-phase) and 20 kW (three-phase). The unit includes optically isolated digital I/O, ±10 V analog control inputs, dedicated brake and drive-ready relay outputs, and multiple analog output channels for monitoring. Its bus voltage range of 141–339 VDC and integrated shunt regulator ensure stable performance during dynamic load conditions. Designed for versatile machine control, the drive incorporates onboard diagnostics and protection against overload, short circuit, and thermal events.
