Its software is modular in structure, the user can freely configurable depending on the application, can be achieved weakening control, tension control, multi-level synchronization. And its interior has a diameter calculation, PID and other software modules can be realized without coiling control sensor. On the hardware side of the series is divided into Double Bridge Road (reversible) 590 series, and a single bridge (irreversible) 591 two sub-series, may be selected depending on the application. It has the power to adapt to a wide range. Can work in 220-500V or 110-220V power supply voltage. In addition, the system is also optional communications and network interface. With other controllers and PC networking, centralized control Detailed technical specifications: Shanghai Zi Cong Electrical Equipment Co., questions about your product, contact our technical engineers: 021-51086047 (30 lines), or 18,917,550,265 Wang.

Working speed 590 series all the latest high-speed control algorithms by 32-bit microprocessor (SCM) is completed, the control software and microprocessor architecture ensures that all control loops regulatory role in the six main circuit thyristor bridge within the conversion time is complete, to ensure that the sampling time of the current loop is less than 3.3ms (50Hz supply) or 2.67ms (60HZ power supply), the speed loop arithmetic operations can be completed within this time, in order to obtain superior dynamic performance. 1.5 man-machine interface MMI 590+ humanized design allows the operator to set the parameters under various conditions, monitoring and fault diagnosis device, all information can be clear on the two-line backlit LCD display, in English (or other languages) displayed. The MMI can achieve local start / stop, speed and steering control given to help set up the debugger. MMI can be installed on 590 devices can be installed in three meters outside the control cabinet panel. Information can be obtained and displayed through the directory menu structure, no search operation manuals or reference code table. All functions and displays are available in four single function key settings and get this single function keys can prevent operator confusion function, an error occurs. Menu Contents include: ■ Diagnosis Diagnosis: display speed feedback, speed deviation, current feedback, the field current / voltage, analog input / output, digital input / output status. ■ Parameter setting Parameter setting: Set parameters for all functional blocks, such as feedback, field control, speed loop operation mode and so on. ■ Password Protection: Password protection of some important parameters are available to prevent misuse. ■ Alarm: Alarm is used to display the current status of the controller. ■ Parameter Storage: good will modify the parameters stored in the EEPROM. ■ Serial port: used to set the communication parameters, such as the serial port baud rate, controller address. ■ System configuration: for analog input / output, digital input / output can be configured. 1.6 provides a magnetic field control 590 thyristor controlled regulator as excitation control, excitation control mode of the motor control can be constant, constant current control and automatic weakening increases the speed (constant power) control. Weakening control can be motor speed, motor current and the magnetic field strength correspond inflection. 1.7 feedback 590+ ways to choose a variety of feedback, they are: ■ ■ coded feedback armature voltage feedback tachogenerator feedback ■ ■ ■ plastic fiber glass fiber Microtach Microtach feedback Feedback 1.8 Protection 590+ protection functions: ■ Energy MOV's ■ ■ instantaneous overcurrent inverse time overcurrent ■ field failure (loss of field) ■ ■ motor speed feedback loss overtemperature ■ SCR module SCR trigger overtemperature ■ ■ internal device failure, network ■ zero speed ■ ■ detection logic block can stall protection 1.9 advanced shell structure in line with international standards of quality, depending on the output current (15A ~ 2700A), means there are six kinds of shell sizes, with different ventilation system (see Table 1), in order to provide The most savings per kilowatt space occupied. Reversible and irreversible device in a shell, its features include: ■ All devices connected to the wires (wire or fiber optic), the use of plug-in connectors are easy to install. ■ All the same circuit board with plug-in replacements. Controllers comply with UL, CSA or EMC standards, machine manufacturers can safely install 590+ shipped overseas.
