Introduction

GT200 series inverter is a high-performance systematic vector inverter, which is a new generation platform product of YiDrive Electric adopting open-loop vector and V/F control mode, and the power range covers 0.75kW-850kW.

GT200 has low frequency torque, motor parameter self-recognition, optimal acceleration and deceleration control, wave-by-wave current limiting and other advanced control performance; with powerful / O expansion function, can be customised for customers to expand the capacity of the process control card, etc.; with to meet the requirements of different processes, such as multi-segment speed control, simple PLC control, PI control, fixed-length control, sag control, automatic energy-saving operation, flexible frequency setting.frequency, various frequency combination methods and combination algorithms and a series of practical functions.

Features

Excellent performance

Steady speed accuracy: ±0.5% Rated synchronous speed (SVC)

Speed control range: 1:100 (SVC)

Torque response: <20ms (SVC)

Heavy load overload capacity: 110% rated stable operation, 150% rated load 1min, 180% rated load 3s

Large low-frequency torque, open-loop vector mode, can achieve 0.5Hz

Stable operation with load (150% rated load)

When there is an instantaneous sudden change in load, the inverter can maintain sufficient torque output capacity and run without tripping.

Wave-by-wave current limiting: it can limit the motor current to a certain level without affecting the output torque It can accurately identify the motor parameters and realise high-performance vector control.

It can realise static self-learning and dynamic self-learning to adapt to different working conditions.

Accurate adjustment of motor parameters can be realised under long-distance cable condition.

Rich and comprehensive application functions

Double-row LED display; Flexible multi-segment V/F curve; Multi-segment speed control; Easy PLC application;

Frequency primary and secondary feed; Pulse frequency input and output; Fixed length control; Speed tracking; Sag control; Automatic energy-saving operation; Motor tone adjustment; Instantaneous stop without stopping

Multi-protection and overload pre-warning; analogue output terminal; automatic running time accumulation; user password setting; built-in braking unit below 22KW; strong expansion capability Excellent adaptability

Wide operating voltage range: rated voltage 220~240V/380V~440V; through the automatic voltage regulation (AVR) technology, long-term low voltage modulation technology, to ensure that the load carrying capacity in a wide range of operating voltage.

Standard EMC design, grid surge, grid noise, electrostatic immunity, to meet the harsh industrial standards 18.5KW or more models can be equipped with optional DC reactor to meet the high power factor, low harmonic requirements of the grid

Carrier frequency selection, according to the environmental humidity, automatic adjustment of the carrier frequency

Power system compatibility: the inverter is suitable for neutral grounded grid system, when the inverter is installed in ungrounded IT power system or high impedance (more than 30Ω) grounded power system, or in corner grounded TN power system.

When installing the inverter on ungrounded IT power systems or power systems with high impedance (more than 30 Ω) or on corner-grounded TN systems, the internal EMC filter is disconnected by removing the EMC screws of the safety capacitor bank.

Comprehensive three-proof paint spraying protection, independent air duct design, optional dust accessories to increase the overall protective capacity to meet the high humidity or dust exceeding the standard occasions for long-term reliable operation.

Fan easy to replace: without disassembling the machine to achieve rapid replacement of the fan, to adapt to the special environment fan replacement, adapted to the frequent need to clean up the air duct debris in special occasions.

Supports wall-mounted, cabinet and through-wall installation, and the keyboard can be led out directly.

Scope of application

It can be used in the drive of automatic production equipment of machine tools, cables, textiles, paper, food, packaging, chemical industry, municipal engineering and so on, to meet the needs of different industrial equipment for performance and function.
