RENLE/RENOLD RNB1055G/075P

Features:

In the V/f control mode, the high-precision current limit control makes the driver no matter whether it is fast acceleration and deceleration or stalled, there will be no overcurrent alarm, and the driver is reliably protected; In vector control mode, the high-precision torque limit control enables the driver to output strong torque or soft torque according to the user's process control requirements, and reliably protect the mechanical equipment.

In the V/f split 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 provides a smooth and shock-free start to the rotating motor.

Process PID control with rich giving and feedback methods, two sets of proportional, integral, and derivative parameters can be switched freely.

It is especially suitable for energy-saving applications such as fans and pumps.

It supports the input of DC power supply, which is convenient for users to form the application scheme of common DC bus.

Overvoltage stall protection: When the large inertia load is decelerated rapidly, the energy may cause overvoltage failure, and the instantaneous adjustment of the output frequency can reduce the probability of overvoltage tripping 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 the constant voltage of the DC bus, so as to ensure the continuous operation of the drive in a short period of time, which is suitable for fans, centrifugal pumps and other applications.

Over-current velocity protection function: When the overload is rapidly accelerated, the instantaneous slip is too large and may lead to over-current failure, and the instantaneous adjustment of the output frequency can reduce the probability of over-current tripping and ensure the continuous and reliable operation of the system.

Low-frequency oscillation suppression function: For high-power motors that will cause violent oscillations when starting at no load or light load, resulting in fault tripping, turning on this function can suppress low-frequency oscillation and ensure the reliable operation of the system.

Automatic torque: In the 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.
