Abstract

The embodiment of the invention provides a control method for a motor drive and a motor driving system, and relates to the technical field of driving control. The method is applied to the motor driving system, the motor driving system comprises a controller, a first drive, and a second drive, and the first drive and the second drive are respectively bound with address information. The method includes: the first drive obtains a control instruction sent by the controller, and the control instruction comprises target address information; whether the target address information and the bound address information are the same is determined; the operation corresponding to the control instruction is performed if the target address information and the bound address information are the same; and if the target address information and the bound address information are not the same, the control instruction is sent to the second drive so that the second drive determines whether the target address information and the bound address information are the same. According to the control method for the motor drive, network control of a plurality of drives can be realized via one controller, extra hardware is not needed, the development period is effectively shortened, and the development cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of drive control, in particular to a control method of a motor driver and a motor drive system. Background technique [0002] The motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses received. Without being affected by load changes, when the driver receives a pulse signal from the controller, it will drive the motor to rotate a fixed angle in the set direction. [0003] At present, one controller is often used to control one driver in the prior art. If multiple drivers are to be controlled, additional corresponding hardware needs to be added to the controller, which increases the difficulty and cost of development. Contents of the invention [0004] In view of this, the purpose of the embodiments of the present inv...
