Product Features

The RNB5000 series variable frequency Inverter 60Hz speed controllers feature a high-end control platform, abundant interface resources, multiple communication methods, advanced control algorithms, and flexible expansion interfaces, enabling them to meet the demanding standards of production processes in many high-end applications.

They use the new generation of motor control-specific digital signal processors (DSPs) from TI, with a main frequency of up to 150 MHz.
The drive utilizes fourth-generation IGBT modules from Germany's Infineon, which feature a maximum junction temperature of 175 °C, and employs an innovative PWM modulation method to further reduce switching losses.
The drive supports both asynchronous motors and permanent magnet synchronous motors, with precise parameter identification for each motor type. Two sets of motor parameters can be configured, allowing the drive to switch between controlling two different motors. The switching function can be set via communication or multifunction terminals.
In VI/F control mode, high-precision current limiting control ensures that the drive does not trigger overcurrent alarms during rapid acceleration, deceleration, or stalling, reliably protecting the drive. In vector control mode, high-precision torque limiting control allows the drive to output either strong or gentle torque according to user process requirements, reliably protecting mechanical equipment.

Control Mode	Starting torque	Speed range	Speed accuracy	Torque response
V/F control	0.5Hz 180%	1:100	±0.5%
No PG vector control	0.5Hz 180%	1:100	±0.2%	＜10ms
With PG vector control	0 Hz 200%	1:200	±0.2%	＜5ms

In V/F separation control mode, the output frequency and output voltage can be set independently, making the drive suitable for applications such as variable frequency power supplies and torque motor control.
The intelligent expansion port allows two expansion cards to be connected simultaneously, meeting industry-specific control requirements.
When an encoder is not installed at the motor shaft end, PG vector control can still be performed as long as the shaft maintains a fixed reduction ratio with the motor shaft.
The drive provides accurate and reliable speed detection, enabling smooth, shock-free motor startup.
The 60 Hz inverter supports process PID control with multiple setpoint and feedback methods, allowing free switching between two sets of proportional, integral, and derivative parameters, and selection of either positive or negative action characteristics.

Particularly suitable for energy-saving applications in fan and pump loads.

DC Power Input Support: Allows flexible configuration of user-defined common DC bus applications.
Overvoltage Stall Protection: During rapid deceleration of high-inertia loads, regenerative energy may cause overvoltage faults. The drive instantly adjusts the output frequency to reduce the likelihood of overvoltage tripping, ensuring continuous and reliable system operation.
Undervoltage Regulation: During momentary undervoltage or power outages, the output frequency is automatically reduced to maintain a constant DC bus voltage, allowing the drive to continue operating for a short period. This is suitable for applications such as fans and centrifugal pumps.
Overcurrent Stall Protection: During rapid acceleration under heavy load, excessive instantaneous slip may cause overcurrent faults. Instant adjustment of the output frequency reduces the likelihood of overcurrent tripping, ensuring continuous and reliable operation.
Low-Frequency Oscillation Suppression: During no-load or light-load startup of high-power motors, severe oscillations may occur, potentially causing faults. Enabling this function effectively suppresses low-frequency oscillations, ensuring reliable operation.
Wave-by-Wave Current Limiting: During heavy-load startup or sudden load increases, the output current is automatically limited before an overcurrent fault occurs, preventing frequent drive tripping.
Parameter Backup Functionality: Parameters can be backed up and restored easily, simplifying debugging and maintenance.
