< ., Overview
< .All control algorithms are completed by a high-speed single-chip microprocessor (single-chip microcomputer). The structure of the control software and the working speed of the microprocessor can ensure that the adjustment of all control loops is in the main circuit six It is completed within the conversion time of each thyristor bridge to ensure that the sampling time of the current loop is less than 3.3 (power supply) or . (power supply). The speed loop algorithm operation can also be completed within this time to obtain superior dynamic performance. For reversible devices, the non-circulation time when the torque (current) is reversed is very short (and can be set by software and set at the factory), so that the current loop has superior performance and response to impact loads. The fully digital DC speed control device has an extended set of silicon-controlled trigger control circuits, which can obtain a wide range of phase shift control and can be applied to both unidirectional and bidirectional reversible control of motor armature voltages with the same power. A set of self-tuning (-) algorithms provided in the machine can automatically calculate the current loop, constants and current interruption points after the control device and motor are combined. This function only requires a simple operation on the operation key. It can be obtained, so that the system can obtain the best kinetic energy characteristics and greatly shorten the debugging time. The current loop also has an adaptive function even when the load changes greatly. The system also achieves smooth speed response. The speed loop has a wide parameter adjustment range and has an integral separation function. The main performance indicators are as follows Speed range Tacho feedback Steady state accuracy ● Encoder feedback with digital setpoint (serial connection or 3) ? ● Analog speed feedback ? ● Voltage feedback ? ● Absolute accuracy using digital controller Degree (.Error) Note: Long-term simulation accuracy depends on the stability of the tachometer temperature. The protection function series has more than ten kinds of protection measures, they are ●Internal devices, network ●High energy' ●Overcurrent (instantaneous and inverse time limit) ●Loss of excitation ●Loss of speed feedback ●Motor overtemperature ●Thyristor module overtemperature (Forced air-cooling unit) ●Thyristor trigger failure
●Zero speed detection interlock ●Static logic ●Stall-rotor protection Configurable terminal allocation and common function modules
