Abstract

The invention discloses an EtherCAT bus-based motor control system. On one hand, a controller can be connected with each slave station device provided with an EtherCAT bus interface through the EtherCAT bus, as the EtherCAT bus itself has a clock function, the delay time of the slave station device can be calculated automatically, the delay time of the slave station device can be calibrated at thesame time, the problem of different delay time of each slave station device under a different environment can be overcome, and clock consistency of each slave station device can further be ensured; and on the other hand, each slave station device is also connected with the motor, the controller can send a control instruction to the motor to control the motor through the EtherCAT bus and the slavestation device, and as the clock of each slave station device is consistent, clock of the motor connected with each slave station device can further be further ensued to be consistent.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a motor control system based on the EtherCAT bus. Background technique [0002] When industrial equipment is running, there are generally many motors, and each motor needs a motor servo to drive. At present, the control of the motor is mainly realized by the controller directly sending control commands to the motor servo. If the number of motors is small and the requirements for the action time delay of each motor are not high, the demand can be met. However, if the number of motors is large and the action time delay requirement of each motor is small, the use of the controller to directly send control commands to the motor servo cannot meet the requirements, because the core of the controller is the CPU, and the CPU can only Execute each command, so the commands sent to the motor servo are sequential, and the delay is unavoidable. Although the delay can be calculated in advance and...
