NL100 series inverters are suitable for three-phase squirrel cage asynchronous motors. Its compact structure, high reliability, widely used in fans, pumps and various equipment, ceramic machinery, machine tools, woodworking machinery, packaging and printing machinery, material handling equipment and other general equipment (conveyors, elevators), etc.

Features:

The NL100 series frequency inverter speed regulator improves the production efficiency for the majority of users by virtue of its compact structure, powerful function and convenient use.

○ In the V/f control mode, the high-precision current limit control makes the drive no matter whether it is fast acceleration, deceleration or stall, there will be no over-current alarm, reliable protection Drive; In the vector control mode, the high-precision torque limit control enables the drive to output strong torque or soft torque according to user process control requirements, and reliably Protect mechanical equipment.

○ In the V/f separation control mode, the output frequency and output voltage can be set separately, which can be applied to applications such as variable frequency power supply and torque motor control.

○ The speed search is accurate and reliable, and it can start smoothly without impact on the rotating motor.

○ Process PID control, with rich reference and feedback modes, free switching of two sets of proportional, integral and derivative parameters. Especially suitable for energy-saving applications such as fans and pumps.

○ Support the input of DC power supply, which is convenient for users to compose a common DC bus application scheme.

○ Overvoltage stall protection: When a large inertia load is running at a rapid deceleration, the regenerative energy may cause an overvoltage fault. The instantaneous adjustment of the output frequency can reduce the probability of overvoltage trip and ensure the continuous and reliable operation of the system.

○ Undervoltage regulation: In the event of instantaneous undervoltage or instantaneous power failure, the output frequency is automatically reduced to maintain a constant DC bus voltage to ensure continuous operation of the drive in a short time, suitable for applications such as fans and centrifugal pumps.

○ Over-current stall protection function: During heavy load and rapid acceleration, excessive instantaneous slip may cause over-current faults. The instantaneous adjustment of the output frequency reduces the probability of over-current tripping and ensures the continuous and reliable operation of the system.

○ Low-frequency oscillation suppression function: For high-power motors when starting with no load or light load, severe oscillations will cause fault trips. Turning on this function can effectively suppress low-frequency oscillations and ensure reliable system operation.

○ Automatic torque boost: In V/F control mode, the output torque can be automatically adjusted according to the load condition to adapt to light load, no load or even overload starting.
