Universal Drive Modules

The MP4Udc is a modular, rack-mounted, configurable multi-axis servo drive system. It consists of a Slave Motion Controller, power supply, and drive modules designed for OEMs with demanding multi-axis motion control applications. The drive modules can be controlled by any ACS SPiiPlus platform EtherCAT master. They utilize powerful servo control algorithms to optimize the performance of the motion system.

For the drive modules, two types can be selected: the NanoPWM for the most precise performance regarding position jitter, settling time, and speed accuracy, and the economical PWM drives. The integrated universal servo controller provides the system designer with flexibility to control virtually any type of motor. Optionally, the Safe Torque Off (STO) function is available, which complies with SIL-3 and PLe safety requirements.
