Embodiment Construction

[0014] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.

[0015] As we all know, there is a position control mode in the servo drive control system. In this control mode, the driver can receive the pulse signal from the host computer (CNC system, PLC, etc.) to precisely control the servo motor to the position specified by the host computer. In addition, there is also an internal position control mode in the servo drive control system, which is equivalent to the position control mode and precisely controls the operation of the servo motor through pulse signals.

[0016] Different from the position control mode, the pulse signal in the internal position control mode does not come from the host computer, but comes from the inside of the s...

Abstract

The invention provides a tilting plate cutter storage servo absolute value motor control method. Because a absolute position encoder motor, after a servo driving system is power off, the position of the servo motor is still memorized, even if the motor position is changed, corresponding encoder data are changed as follow. Initialization detection is conducted on the servo motor after power on, themotor position is read and compared with a target position before power on, if the read motor position during power on is not in the target position range, the motor is triggered to operate to the target position before power off, when the operation is in place, the cutter number coding and a cutter replacement finish signal are outputted. The method has the advantages of simple structure and high reliability.

Description

technical field [0001] The invention relates to the technical field of tool magazines, in particular to a method for controlling a servo absolute value motor of a swash plate tool magazine. Background technique [0002] In motion control, there are often some unexpected external factors (such as the moment when the motor is powered on or off, the actual mechanical position deviates too much from the previous one due to the heavy load, and the sudden Power outage, causing the machine not to stop at the expected position, etc.), causing the machine to leave the original actual position after power outage. It is a tool magazine, which can damage the machine and cause casualties in serious cases. Even if it is found that the actual mechanical position has shifted, we need to recalibrate the machine, wasting time, manpower, and resources. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the disadvantages o...
