Product Overview

Feature

■ AC Motor VFD Open - loop vector, Closed - loop vector, Open - loop torque, Closed - loop torque control.

■ Inverter operates stably without tripping under any acceleration and deceleration time and any impact load.

■ Real torque control is realized through the independent current loop control, and online switching between torque control and speed control is supported.

■ Independent input and output port of high speed pulse, which can realize high speed pulse cascade function.

■ Accurate speed identification and rotor flux orientation, the torque can also respond quickly and operate stably when a load of 0.25hz breaks.

■ High-precision current detection and protection, high-precision hall to detect output current, realization of fast real-time control and protection of software and hardware, and assurance of performance and reliability of the whole machine.

Technical Specification

Motor Wiring

It is forbidden to short circuit the 3 phase frequency Inverter output terminals or short circuit to ground, otherwise the internal components of the variable frequency inverter will be damaged.

Do not short circuit the output cable to the universal variable frequency drive enclosure, otherwise electric shock may happen.

It is forbidden to connect the output terminal of the inverter to the capacitor or LC/RC noise filter with phase lead, otherwise, the internal components of the inverter may be damaged.

When contactor is installed between the inverter and motor, it is forbidden to switch on/off the contactor when the High Speed Drives is running; otherwise, large current will flow into the industrial inverter, triggering the inverter protection action.

Length of cable between the High Frequency Inverter and motor. If the cable between the frequency inverter and the motor is too long, the high−order harmonic leakage current of the output end will cause adverse impact on the Single Phase To 3 Phase Inverter Converter and the peripheral devices. Output AC reactor should be installed if the motor cable is longer than 100m, Refer to the following table for the switching frequency setting.
