Take 18.5G/22L for example: the model without brake unit is GK600-4T18.5G/22L, and the model with brake unit is GK600-4T18.5G/22LB. Braking resistor needs to be mounted externally with reference to Table 3-3.** means the rated input current configured a DC reactor. The drive GK600-4T90G/110L or above is provided with an external-mounted DC reactor in shipment as default. Be sure to connect the DC reactor. Failure to comply may result in drive abnormal running.4.Technical Features of GK600 Frequency Changer (VFD)Table 3 Technical Features of GK600 Frequency Changer (VFD)Power inputRated input voltage3-phase AC208V/220V/230V/240V/380V/400V/415V/440V/460V/480V1-phase AC220V/AC230V/AC240VRated input currentSee Section 2.3 in the User ManualFrequency50Hz/60Hz, tolerance ±5%Allowable range of voltageContinuous voltage fluctuation ±10%, short fluctuation -15%~+10%, i.e. 323V~528V;Voltage out-of-balance rate<3%, distortion rate as per the requirements of IEC61800-2Power outputStandard applicable motor (kW)See Section 2.3 in the User ManualRated current (A)See Section 2.3 in the User ManualOutput voltage (V)3-phase: 0~ rated input voltage, error < ±3%Output frequency (Hz)0.00~ 600.00Hz; unit: 0.01HzOverload capacity150% - 1min; 180% - 10s; 200% - 0.5sControl characteristicsV/f patternsV/f controlSensor-less vector control 1Sensor-less vector control 2Range of speed regulation1:100 ( V/f control, sensor-less vector control 1)1:200 (sensor-less vector control 2)Speed accuracy±0.5% (V/f control)±0.2% (sensor-less vector control 1 & 2)Speed fluctuation±0.3% (sensor-less vector control 1 & 2)Torque response< 10ms (sensor-less vector control 1 & 2)Starting torque0.5Hz: 180% (V/f control, sensor-less vector control 1)0.25Hz: 180% (sensor-less vector control 2)Basic functionsStart frequency0.00~ 600.00HzAccel/Decel time0.00~60000sCarrier frequency0.7kHz~16kHzFrequency setting sourcesDigital setting + keypad ∧/∨Digital setting + terminal UP/DOWNCommunicationAnalog setting (AI1/AI2/EAI)Terminal pulse settingMotor started methodsStarted from starting frequencyDC braking and then startedSpeed search startedMotor stopped methodsRamp to stopCoast to stopRamp stop + DC brakeBasic functionsDynamic braking capacityBrake unit action voltage: 650V~750V; service time: 0.0~100.0s; brake units for GK600-4T45G/55L and below are built in or can be built in.
