JL960 full English LCD series frequency converter

JL960 full English LCD series frequency converter, using DSP control system, to complete the speed sensor-free arrow control, compared with V/F control, the arrow control has greater advantages, positioning and the load application of the specific requirements of OEM customers in the mid-end market, the design is active, embedded SVC (no PG arrow control) V/F control in one, can be widely used for speed control accuracy, turnover cabinet response speed, low-frequency output special
Applications with high requirements.
■Three speed control modes: vector control without speed sensor (SVC), vector control with PG (VC>, V/F control, torque control;
■Automatic tuning of static and rotary motor parameters;
■ Realize high-precision closed-loop speed control and torque control;
■ Adopt dual CPU control platform (DSP+ARM);
■Load: 150°/. Rated current 60s, 180% rated current 10s;
■ Starting cabinet: no PG arrow maximum control 0.5Hz/150% (SVC); PG Arrow Control 0Hz/180% (VC);
■ Speed control range: 1:100 (SVC), 1:1000 (VC>;
■ Carrier frequency: 1.0kHz ~ 16,0kHz;
■Torque control function: provide a variety of torque setting sources;
■Simple PLC, multi-speed and PID control, swing frequency function;
■Automatic voltage adjustment: it can automatically keep the output voltage constant when the grid voltage changes;
■ Provide RS485 serial communication interface, using standard Modbus communication protocol;
■ 0.4-22KW built-in brake unit for each specification, (30KW built-in brake unit needs to be equipped) If you need to stop quickly, you can directly connect the brake resistor;
■ It has a power-down reset function to ensure the continuity and efficiency of production.
