A 2-axis motion controller, the DMC-1425 is designed to provide both RS232 and Ethernet communications links for easier, high speed, and long distance communications between any number of computer hardware devices. It also supports the Modbus protocol for easy communication with I/O devices. Additionally, it controls both step- and servomotors, includes linear and circular interpolation for coordinated motion along two axes, and includes uncommitted digital inputs and outputs, and two uncommitted analog inputs.

The SERVOSTAR CD drive amplifier, for three-phase brushless permanent magnet servomotors, has current ratings for 3 to 10 amps for 115 to 230V ac operation. It is designed for direct connection to 230V line mains. Both the 3 and 6 amp models offer 3:1 peak-to-continuous ratings and the 10-amp model has 2:1 peak-to-continuous. These models also have the option of accepting control voltage through an external 24V supply to increase control flexibility.

The Stepper/Servo family was specifically designed and engineered to offer users a choice in sizes and features need for specific applications. Consisting of models FEB, RFEB, and SSB, all brakes are power-off, or "failsafe" units that mount to the front end of a stepper or servomotor as an added safety feature or for holding the load in place.
