Abstract:
1. A servo drive with high speed wrapping function, which is used for a servo control device with a wire wrap controller, the servo device comprising: at least one wrapping mechanism; a rotation control unit for controlling rotation of the wrapping mechanism; a lateral motion control unit, including a servo motor and a servo drive for driving the servo motor, for controlling lateral reciprocating movement of the wrapping mechanism; and an origin detector for detecting a wrap origin, wherein the servo drive further comprises a wrap command processor and a software built in the wrap command processor for setting and calculating function parameter and outputting control command, and wherein the wrap command processor comprises: a signal converter for receiving the voltage level analog signal of the potentiometer; a first low-pass filter connected to the signal converter and outputting a voltage level digital signal; a pulse type selector for receiving pulse signal of the encoder; a counter connected to the wrap controller and outputting a counted signal; and a wrap controller connected to output end of the first low-pass filter and the counter and used for software computation on received signal, the wrap controller used with internal software and set parameter and the voltage level analog signal of the potentiometer and the pulse signals of encoder to calculate pulse commands of servo motor.
