DAP03 AC Spindle Servo Driver
DAP03 with wide timing range, small speed fluctuation and short starting/braking time, DAP03 AC Asynchronous Spindle Drive Unit realizes digital vector control of AC asynchronous motor to gain exact positioning of AC asynchronous motor. It is the optimum choice to improve performance and reduce the cost of CNC machine.
High performance DSP and CPLC to realize digital control and high reliability;
High pressure AC busbar(600V), big power IPM, excellent dynamic response;
Asynchronous motor vector control, wide valid timing range and small speed fluctuation;
External contact signal can the spindle orientation and set 8 positioning points;
Three-phase 380V direct input without power transformer to get the convenient installation and low cost.

Note 1: The servo motor with the special polar and the basic frequency is specially ordered, and the optional servo unit must use the exclusive software; max. speed of the standard allocation servo motor is 6000r/min, and the motor with more 6000r/min speed is ordered specially;
Note 2: When the ratio between the servo motor and the spindle is 1:1 without gap drive, the spindle can complete the exact orientation without the spindle encoder; when the ratio is not 1:1, the spindle cannot does without the spindle encoder.
Depends on AC servo spindle motors sizes, the AC servo drivers model name could be DAY3025 or DAY3100 also
