InWitten CHF100A series vector universal frequency converter
WS
1. Power range is 1.5kW~3MW
2. Three control methods: no PG vector control (SVC), V / F control, and torque control;
3. Start-up torque: no PG vector control: 0.5Hz / 150% (SVC);
4, 18.5kW~90kW frequency converter built-in DC converter to improve the input side power factor, improve the efficiency and stability of the whole machine;
5. Built-in brake units of 1.5~15kW specifications. If quick parking is required, the brake resistance can be directly connected;
6.16 Simple PLC, multi-segment speed control and PID control;
7. Support a variety of frequency setting methods: number setting, simulation amount setting, PID setting, communication setting, etc.;
8. Support the start and stop of DC braking;
9. Input and output terminals are freely programmed, and users can combine a variety of working modes according to their needs;
10. Have the jump frequency control function to avoid mechanical resonance and make the system more stable and reliable;
11. Have the function of instantaneous power loss without shutdown;
12 Have the dormant wake-up delay setting function;
13. Have the excessive torque detection function;
14. Multiple ceiling frequency setting source selection;
15. Real-time parameters can be viewed through the shift key with the two-way displacement function;
16. Have the speed tracking and restart function: to realize the impact-free smooth start to the motor in the rotation;
17. QulCK / JOG function: users can freely define the multi-function shortcut key, by setting this parameter can quickly browse the modified related function code different from the factory default value;
18. With automatic voltage adjustment function: when the power grid voltage changes, automatically keep the output voltage constant;
19. With the oscillation suppression function: to effectively solve the problem of low-frequency oscillation of high-power motors;
20. Provide a variety of fault protection functions: over-current, over-pressure, under-pressure, over-temperature, phase absence, overload and other protection functions.
