Embodiment Construction
[0031] The embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings. The following descriptions about the embodiments of the present invention are only exemplary, and are not intended to limit the subject matter to be protected in the present invention. There are other aspects of the described embodiments of the present invention. Changes within the protection scope of the claims all belong to the subject matter that needs to be protected in the present invention.
[0032] According to shown in accompanying drawing 1: control flow comprises the following steps:
[0033] 1) Parameter collection
[0034] The controller collects the eight state parameters of key closure, contactor closure, interlock closure, direction closure, emergency brake flag, accelerator, motor steering, and motor speed in real time according to the frequency of the internal clock.
[0035] The state parameter returned by the emergency brake f...

The invention discloses a separately excited motor control flow, which comprises three steps of: acquiring parameters; executing; and switching into other control flows, wherein eight state parameters, i.e., key closing, contactor closing, interlocking closing, direction closing, an emergency control flag bit, accelerator, motor rotation direction and motor rotation speed are acquired in real time by a controller according to frequency of an internal clock and each parameter value is judged; and seven working modes, i.e., an emergency braking mode, a reversing mode, an acceleration mode, a deceleration mode, a direction brake mode, an interlocking brake mode and control flow jump-out are realized. The invention aims to overcome the disadvantages in the prior art and provides the separately excited motor control flow which can realize effective driving control, rich parameters and rich working modes and can be suitable for various working requirements of a separately excited motor.
Description
technical field [0001] The invention relates to the field of motor control, and more specifically relates to a control flow applicable to separately excited motors. Background technique [0002] The traditional separately excited motor does not collect many parameters in the control process of the motor, and the working mode that can be realized is also very simple. In the actual operation situation, the too simple working mode classification cannot deal with all possible situations. There are few working modes that can be executed, and it is doomed that the function of the traditional separately excited motor is insufficient, and because the setting of the condition parameters is not detailed enough and the jump between the working modes is too large, the switching of each working mode is not smooth. Therefore, the traditional other The control process of the excitation motor needs to be improved in design. Contents of the invention [0003] The purpose of the present in...
