The invention provides a method for controlling the speed of a variable-frequency electric locomotive by setting parameters. The method comprises the following steps: S1, detecting the rotating speed of the variable-frequency electric locomotive; s2, the control keyboard is connected with the electric locomotive mainboard through a data line; s3, after entering an interface, pressing a PAR key to enter a parameter mode; s4, the reverse rotation speed is modified, and the rotation speed of 2200 is decreased progressively to about 1600-1800 revolutions according to a single arrow; s5, modifying the forward rotation speed, and decreasing the rotation speed of 2200 to about 1600-1800 revolutions according to a single arrow; s6, the rated rotating speed is set, and the rotating speed of 1450 is gradually decreased to about 1000-1150 revolutions according to a single arrow; s7, pressing a green key again, and starting and activating parameters; and S8, the running speed of the electric locomotive is detected through actual running. By means of the method, the maximum speed of the electric locomotive is controlled to be 4 meters per second, the electric locomotive can be effectively controlled to operate, a driver of the electric locomotive can stably control the electric locomotive, and stable and safe operation of the electric locomotive is guaranteed.
本发明提供了变频电机车设定参数控制速度的方法,包括有以下方法步骤:S1、先实现对变频电机车的转速进行检测;S2、将控制键盘通过数据线与电机车主板连接;S3、进入界面后,按PAR键进入参数模式;S4、修改反向转速,按单箭头将2200转速递减到约1600‑1800转;S5、修改正向转速,按单箭头将2200转速递减到约1600‑1800转;S6、额定转速,按单箭头将1450转速递减到约1000‑1150转;S7、再按绿色键,启动、激活参数;S8、实际运行实现对电机车的运行速度进行检测。通过本方法使得电机车最大速度控制在4米/秒,能够有效的控制电机车在运行的时候,使得电机车司机能够稳定的控制电机车,保证电机车的运行稳定和安全。
