ClearPath – Nema 34 8.5 Nm Servo Motor
The ClearPath-SDSK model allows you to precisely servo-control position (and velocity) using “step & direction” (or quadrature A/B) command signals. These digital signals are commonly used to control stepper motors and digital servos, so they are available from a wide variety of products including PLCs and stand-alone motion control “indexers”. Compared to ClearPath-SDHP models, which also use step & direction control signals, the SDSK models have less peak torque, but are a lower price for any given amount of continuous (RMS) shaft torque and power.
One ClearPath input counts steps from your motion controller, the other input determines if the steps are made in the clockwise or counter-clockwise direction.
Quadrature input allows you to use the output of a quadrature encoder to command position and speed. Or, you can use an indexer or PLC with quadrature outputs to command at a speed that is 4x the output frequency (because each edge counts as a “step”).
