Introduction to Easy Servo
The ES (Easy Servo) series easy servos offer an alternative for applications requiring high performance
and high reliability when the traditional servo was the only choice, while it remains cost-effective.
The system includes an easy servo motor combined with a fully digital, high performance easy servo
drive. The internal encoder is used to close the position, velocity and current loops in real time, just
like servo systems. It combines the best of servo and stepper motor technologies, and delivers unique
capabilities and enhancements over both, while at a fraction of the cost of a servo system.
Getting Start
To get start you need one easy servo drive, one easy servo motor (stepper drive with encoder) and an
AC / DC power supply for the first time evaluation. A motion controller - like indexer, pulse generator
or PLC is required too if you would like to verify the complete function. If you have a PC with one
serial port or one PC with USB-RS232 converter, you can also rotate the motor in the PC software.
However it is recommended to verify the complete function of the easy servo using another motion
controller.
