Embodiment Construction
[0026] Such as figure 1 As shown, the electric transmission control system for converter tilting includes PLC (programmable logic controller) controller, multiple frequency converters and tilting speed encoders, which are connected by PROFIBUS-DP (distributed peripheral equipment process field bus) bus together. Each frequency converter controls its corresponding motor. Such as figure 2 As shown, the inverter can use Siemens 6SE70 inverter, and the inverter is connected to the PROFIBUS-DP bus through the CBP2 communication board.
[0027] The control method of the above-mentioned control system comprises the following steps:
[0028] 1) Configure the PROFIBUS-DP network, and then run the control system;
[0029] 2) The PLC controller sends the torque command value to the frequency converter through the speed regulator set by its internal program, and the frequency converter then adjusts its corresponding motor according to the command;
[0030] 3) The tilting speed encod...
