● thyristor triggering failure ● zero speed detection interlocking ● static logic ● configurable terminal distribution and common function modules of locked rotor protection. Except for speed / current setting and feedback terminals, all other analog and digital input and output terminals of 590 series can be reassigned and defined, and connected to the nodes required by the control software module diagram, which makes 590 series have variable application performance. In addition, the 590 series of standardized control software has many functions and modules required for transmission applications, For example: ● winder control module (constant tension control) ● PID control module ● digital slope function ● multi machine drive control ● speed rise rate and fall rate control controlled by digital input ● speed given "s" Type a slope generator ● inching / crawling / tightening control function ● moment of inertia compensation ● zero speed position ring device i/o end and system module configuration can be achieved through LCD or upper computer operation. The magnetic field control 590 series provides a voltage regulator controlled by thyristor as the excitation control of the motor. The magnetic field control mode can be constant voltage control, constant current control and automatic field weakening speed-up (constant power) control. The field weakening control mode can correspond the motor speed, armature current inflection point and magnetic field strength. Diagnosis and monitoring the comprehensive diagnosis and monitoring information of alarm, operation status and parameter setting can be continuously displayed on the LCD in a clear format. Any fault signal that stops the driving device is immediately locked and displayed, so that the operation can be immediately confirmed and corrected. All diagnosis, working parameters and setting information can also be obtained through the serial port for (off-site) remote analysis.
