Note: Turning Speeds and DC Motors
Use the electronic variable speed control in combination with the step pulley. Variable speed DC motors
may have poor torque (power) at low speeds. Use the lower speed pulley steps for better torque. The
available speeds will be from zero up to the maximum speed of the pulley step.
In general, select a belt setting in the lower 4 steps to provide good torque when turning. Use the upper
steps only when higher speed spindle turning is required.
