2. System Function 2-18 DVP-MC operating manual Serial Default Parameter Name Function Data Type No Value 19 Max.Deceleration The available max. deceleration; (Unit: unit) REAL 10000 Parameters 17~19 are used in the specific situation. E.g. The velocity, acceleration and deceleration of G0 in instruction CNC; the velocity, acceleration and deceleration at which slave enters the state of meshing with the master axis when Cam in; the velocity, acceleration and deceleration at which slave follows the master to move when Gear in. 20 Position The current position of the servo drive (Unit: Pulse) DINT 21 Velocity The current speed of the servo drive (Unit:
0.1 rpm) DINT 22 Torque The current torque of the servo drive ( Permille of the rated torque) INT Above three parameters are used for setting DVP10MC11T to adjust PID of servo drive 23 Current The present current of the servo drive ( Permille of the rated current) INT 24 User defines parameter Servo drive parameters customized by users “User defines parameter” is the servo drive parameter to be read. Its length is specified according to the data type of the read parameter. The byte parameter length is 1; the word parameter length is 2 and double-word parameter length is 4. The method of calculating sub-index and index of the servo drive parameter is shown below:
Index= Servo drive parameter (Hex) + 2000 (Hex), Sub-index=0 For example: The index of servo drive parameter P6-10: 2000+060A (P6-10 hex.)=260A; sub-index: 0. Cyclic communication data can be selected by users. The data length selected can not exceed 8 bytes which can be calculated by computer automatically. The data length of position, speed, torque and current are 4 bytes, 4 bytes, 2 bytes and 2 bytes respectively. The current value of cyclic communication data selected by user can be read by the special registers related with axis. See appendix C for more details.
