4. Motion Control Instructions 4.4.14. DMC_WriteParameter Explanation of the Instruction: DMC_WriteParameter is applied to set the parameter value of the servo axis. User could specify the index and sub-index of the parameter to be set. Explanation of input and output parameter of the instruction: Notes: 1. "Data Type" must be the data type of the written parameter. If the filled value is incorrect, the instruction will be alarmed that the error occurs with the error ID. The data type of D device is identical to that of the written parameter when "Value" is D device and touch screen is used to input data. 2.
For the calculation method of the index and sub-index, please refer to section 4.4.13 DVP-MC operating manual 4-47 API Write parameters Controller 14 DMC WriteParameter _ 10MC11T Parameter Data Available Explanation name type device Axis The node address of servo drive UINT Constant, D Execute This instruction is executed when “Execute” turns off -> on.
