SC400 servo drives, manufactured by Pacific Scientific, represent one of the best modern day drive series for analog velocity and torque control.
These drives are capable accepting any analog command given to the drive. They have a velocity and torque control output which is proportional to a + or – 10V input. For velocity control, the end user must close the position of the loop. For torque control on SC400s, the end user must close the velocity and/or the position of the loop. These drives are rated to have either a 30/1,500 to 23/3,000 maximum continuous rated torque for pounds per inch.
