2. System Function 2-16 DVP-MC operating manual Serial Default Parameter Name Function Data Type No Value 5 Software Limitation Enables software limitation; If the item is not selected, the maximum/ minimum position of the axis which software limits is invalid. If selected, the maximum/ minimum position of the axis limited by software is valid. BOOL 0 6 Maximum Position The max. position of the axis limited by software REAL - 7 Minimum Position The mini. position of the axis limited by software REAL - 8 Acceleration Type Trapezoid/Sinus - Trapezoid The servo motor presents the following features in process of acceleration and deceleration while DVP10MC11T is controlling the servo drive.
Trapezoid: Sinus: 9 Unit Numerator To set the pulse quantity needed when motor rotates for one circle by adjusting unit numerator and unit denominator. UINT 128 10 Unit Denominator To set the pulse quantity needed when motor rotates for one circle by adjusting unit numerator and unit denominator. UINT 1 11 Increment How many pulses are needed when servo motor rotates for one circle. UINT 10000 Adjusting the Unit Numerator and Unit Denominator parameters is to set the electronic gear proportion of the servo drive. Electronic gear proportion is to set how many pulses servo drive receives while servo motor rotates for a circle.
The resolution of A2 servo drive motor is 1280000 pulses/ circle; Suppose the value of parameter 11 is N, N* (Unit Numerator/ Unit Denominator)=1280000
