Teknic SSt-6000-U Digital Servo Drive
The SSt-6000 is a high bandwidth, digital vector servo drive. The seamless integration of position, velocity, and torque loops enables this drive to provide surprising performance enhancements.
For years, Teknic has proven the benefits of tightly integrating servo compensation with torque control under the control of a dedicated DSP per axis. The latest in a line of high performance drives, the SSt-U series advances the state of the art by utilizing this topology in such a way to allow all information to be shared in real time so all system functions cooperate in any situation. For example, if the torque loop senses voltage saturation, that is instantly passed upstream to the servo compensator and the system delivers a coordinated response, maintaining elegant load control. The result is performance superior to other digital servo drives or analog torque amplifiers. OEMs will realize tighter tracking, immediate settling, and smooth motion - all of which yields superior machine throughput and reliability.
The 6000 has an open control interface and will work with almost any servo controller or indexer with little to no software change. Moreover, it will elegantly control permanent magnet servomotors from virtually any manufacturer.

CUTTING EDGE SERVO CONTROL
The SSt-6000-U’s servo performance is the product of two decades of algorithm refinement capitalizing on truly unique design architecture.
Superior Tracking Accuracy
Multi-derivative, state feedforward gains significantly improve tracking performance and do not create the audible noise and torque chatter of traditional implementations.
Zero Settling Time
For demanding point to point applications, the advanced technology of the SSt-U provides zero settling time.¹
Ultra Smooth Motion
Teknic’s proprietary Regressive AutoSpline™ (RAS)technology produces ultra-smooth trajectories. The profiles are jerk and jerk-derivative limited, which reduces shock,vibration, noise, and wear—even in high speed machines.
Adaptive Tuning
The SSt utilizes an adaptive control algorithm (IMT) based on neural fuzzy logic.
The IMT virtually eliminates the concern of inertia matching and allows for loads of large and varying inertia.
Anti-Hunt™
The SSt-6000-U uses small-signal, sliding-mode, automatic gain modulation to eliminate hunting even with extreme gains.
Axes will be perfectly still and have no loss of accuracy.
Ease of Performance
Some systems are high performance and others easy to use.
Few are both. The SSt’s cascading PIV control structure provides cutting edge performance with ease of use.
Even the sophisticated RAS, IMT, and Anti-Hunt are easy to set up
FLEXIBLE, LOW EFFORT INTEGRATION
The SSt has OEM friendly features designed to make upgrading performance quick & painless.
Drop-in Controller Compatibility
U series SSt drives accept a digital trajectory command that is compatible with most indexers and servo controllers and requires little to no software change. This provides a performance upgrade for servos and allows for drop-in stepper replacement.
Universal Motor Interface
SSt drives control rotary and linear servomotors, brush motors, galvos, voice coils, etc. from virtually any manufacturer without electrical restriction on the motor.
