2.3 ABOUT THE SCA06

The servo drive SCA06 is a high-performance product which allows controlling the speed, torque and position
of three-phase, sine-wave, alternate current servomotors. The main characteristic of this product is the high
performance and high precision of movement control of the servomotor shaft due to the operation in closed loop
by means of the position feedback given by a sensor inside the servomotor.
The SCA06 features independent control and power supply, allowing, for instance, that the product communication
networks keep on working normally even if the power circuit must be turned off for some reason.
The use of braking resistors provides greatly reduced braking times, optimizing the processes that require high
performance.
Several special functions are available, such as programming in ladder with positioning blocks, which provides
extreme flexibility and integration to the drive.
The SCA06 can be used in different applications with many options of cables, both for simple applications and
complex applications like handling, environments with oil, etc.
