     The ServoLoc 1 is a fully digital brushless servo motor controller specially designed and manufactured to allow user configurable operation. The ServoLoc 1 with 3Ø sinusoidal motor current operation provides smooth rotation and improved torque repeatability over trapezoidal current type drives.
     RS 485 serial communication of the ServoLoc 1 allows for a multi-axis velocity/torque control environment, with on-the-fly mode change. Since the ServoLoc 1 was designed and developed as an alternative choice for an existing servo drive, additional features are incorporated to interface with a wide variety of brushless motors. Inputs are provided on the terminal block to configure the ServoLoc 1 to operate with various encoder resolutions and motor poles.
     Besides tight servo loop control, the ServoLoc 1 includes features that are not available from competitive type drives. One of the most important features is that the ServoLoc 1 includes a selectable static brake option (shorting 3 motor leads) when the drive is disabled and at low velocity. This option is particularly useful in anti-windup situations. Another useful feature is its ability to coast to stop or ramp (decelerate) to stop and disable when a stop command is initiated.
