INVT frequency inverter GD200A series performance.

More Accurate Motor Autotuning.
Accurate rotating and static motor autotuning Convenient debugging and easy operation.
- Rotating autotuning.
De-couple form the load. Applied to the situation with high control accuracy.
- Static autotuning.
No need to de-couple from the load. Applied when rotating autotuning is not available.
Advanced open loop vector control.
The current, torque and rotating speed waveforms when sudden loading or unloading in asynchronous motor open loop vector control mode with 0.5Hz running frequency and full load.

Perfect voltage and current control, reducing the fault protection times.
OC fault.
- Adjust the output frequency to avoid overcurrent of the inverter during acceleration.
OV fault.
- Adjust the output frequency to avoid overvoltage of the DC bus during deceleration.
Multiple braking modes and instant stopping.
Dynamic braking.
- Configure braking units and resistors 
- Available on the situation of big inertia load and frequent braking 
- Big braking torque and quick braking
Flux braking.
- No need to configure braking units and resistors 
- Available on the instant stopping situation with big inertia load and no frequent bra king
- Not available on the situation of big inertia load and frequent and braking(the energy consumed on the stator and its cooling is better than DC braking
DC braking.
- No need to configure braking units and resistors 
- Available on the situation when start the running motor after braking and the situation when keep the moment output after braking to zero speed
- Not available on the situation of big inertia load or instant stopping braking in high speed running
Short circuit braking.
- No need to configure braking units and resistors, capable of braking quickly 
- Applicable to the motors at quick start and stop or restart after braking 
- Not applicable to big inertia load and frequent braking.

INVT vfd Goodrive200A series is multifunctional and with simple operation.

Separate Air-duct.
The separate air duct prevents the contaminants into the electronic parts/components and greatly improves the protective effect of the inverter, as well as its reliability and service life, to adapt various complicated site environments. It can also facilitate the heat-releasing in control cabinets and the heat-releasing design of the customer.
Multiple installation modes.
0.75~200kW: Wall mounting and flange mounting
200~315kW: Wall mounting and floor mounting
350~500kW: Floor mounting
Remark: above power ratings are subject to G type machine.
Standard built-in C3 input filters, optional external C2 filters.
C3 input filter is embedded in the factory to meet different application requirements,save installation space and avoid electromagnetic interference caused by incorrect selection and site installation.
Remarks:
C2 filter: EMC performance of the inverter achieves the limited usage requirement in civil environment.
C3 filter: EMC performance of the inverter achieves the limited usage requirement in civil environment.
Book structure.
Parallel installation Smaller installation space with less cost and beautiful appearance.
The rivet design ensures reliable integration connection.
- Greener Proper grounding.
- Stronger corrosion-resistance Excellent EMC performance.
Smaller Size.
Due to the thermal simulation and advanced modularized design, the size of our product is reduced greatly. The width ratio between Goodrive300 and CHF100A is shown in the figure below (the Max. percentage is 50%)

GD200A series.
Membrane keypad design (which can be connected to external keypads) is available for inverters (≤15kW); swappable keypads are standard for inverters (≥18.5kW).

INVT frequency inverter GD200A series function of water supply.

In the diagram above, M2 and M3 are auxiliary motors which are controlled by RO1 and RO2. PID constant-pressure automatic control system is formed by the inverter through pressure feedback. The pressure reference can apply analog or keypad input. 485 remote communications is also supported.

Advanced thermal technology and wide voltage range of INVT drive GD200A series.

- Advanced thermal technology makes exact thermal design.
- Wide voltage range meets the requirement of grid environment.
