Flexible Features
Flexible and convenient means for frequency setting ● With operation panel settings (number setting), the operation panel can be adjusted by ∨/∧ for frequency setting ● Terminal setting 1) Analog quantity AI1/AI2: 0 ~ 10V or 0 ~ 20mA; 2) Analog quantity AI3:-10V ~ 10V; 3) Pulse frequency X7/DI: 0.2Hz ~ 50kHz; 4) Xi terminal: Up / Dn independent model, to be overlapped with any other frequency setting. ● Communication setting: international standard Modbus protocol. ● Online switch may be made on the above settings.
Multi-channel for Setting and Feedback ● Under open-loop or analog quantity closed-loop feedback mode, setting quantity may define the relationship between primary and secondary operations: 1) Primary setting + secondary setting; 2) Primary setting - secondary setting; 3) Primary setting + secondary setting - 50%; 4) Maximum value (primary setting, secondary setting); 5) Minimum value (primary setting, secondary setting). ● Positive and negative results between primary setting and secondary operations can automatically define the direction of motor rotation. ● Under analog quantity closed-loop feedback mode, the feedback may also define the relationship between primary and secondary setting operations and then adjust and control process PID. Specially applicable to: A variety of continuous automatic production lines, such as: paper making, printing and dyeing, packaging, printing. Temperature and pressure control occasions, such as: chilled water control of central air-conditioning, water supply systems.
Digital Operation Panel ● Button and shuttle type options, RS485 communication and standard network port connection. ● Button layout complies with human engineering principle by one-touch functional keys for entry and exit, easy to operate. ● Standard configured operation panel is given with functions for copying parameters and remote control box (up to 500m). ● Original multi-functional key M can be customized for the following functions: 1) JOG; 2) Emergency stop 1 (the fastest shutdown); 3) Emergency stop 2 (free shutdown); 4) Setting switch of running commands (operation panel setting → terminal setting → upper PC setting → operation panel setting); 5) FASt / bASE menu switch; ndFt / bASE menu switch; LASt / bASE menu switch; 6) Menu mode order (bASE → FASt → ndFt → LASt → bASE).
Upper PC Communication ● Operation panel and terminals provide RS485 interface and communication protocol Modbus, as well as monitoring software for upper PC. ● Realize principal and subordinate communications control between several inverters. ● Realize uploading and downloading of parameters. ● Realize cascade transmission of operating frequencies of several inverters with digital frequency divider
