Universal Drive Modules

The UDMsa is part of the Universal Drive Module (UDM) series of EtherCAT-based servo drives and includes 1 universal servo drive with an input voltage of 12-150Vdc. The UDMsa delivers an output current of up to 10A nominal and 20A peak at an input voltage of 150 Vdc, and an output current of up to 15A nominal and 30A peak at an input voltage of 100 Vdc. The UDMsa can be controlled by any ACS SPiiPlus platform EtherCAT master and utilizes powerful servo control algorithms (sample frequency=20kHz) to optimize the performance of the motion system.

The integrated universal servo controller offers the system designer flexibility to control virtually any type of motor. With the optional ServoBoostTM algorithm, very high performance can be achieved in terms of standstill jitter, settling time, and speed accuracy. The UDMsa also has a Serial Peripheral Interface (SPI) to be able to read specific feedback systems such as autofocus signals. Optionally, the Safe Stop 1 (SS1) and Safe Torque Off (STO) functions are available, which comply with SIL-3 and PLe safety requirements.
