GD1000 is a special VFD designed for coal mining machines. The main applications are coal mining machines, continuous mining machines, shuttle cars and other traction loads.

1. Check the pump running direction is reversed or not, power off, and exchange U and W cable can change the direction.
2. Some centrifugal pumps need to be filled with water before work properly.
3. The pump head is proportional to the square of the frequency.if the output frequency is too low, it will cause the head of the pump to drop, resulting in not water. it needs to add the solar panel power, and set P15.05 output lower limit frequency.

Models（<=1kW) can support both single phase and three phase 220VAC input; Model(>=)1.5kW) has to connect with three phase 220VAC input, if with single phase 220VAC input, it will affect the maximum speed of motor, and has to use derately, which means a 1.5kW drive may be just uesd as 750W model.

After the BPD is removed the cover to repaired, the protection level will decrease. When installing it again, you need to check whether the waterproof tape is intact, and apply appropriate waterproof glue on the four corners to ensure good sealing.

Please try‘Arial' font first. If it doesn't work, try to copy the language to 'word' document to know the exact font, for example, it should be 'Shruti' font for Indian language. Note: The 'systemFont' file in the installation directory of VS HMITool should have this font format.

No. The CPU is sold without any spare parts including cables; it needs to buy the IO cable and terminal seperately.

-1: with integrated 2 analog inputs and 1 analog output;
-2: with removable ternimal;
-6: with integrated 2 analog inputs and 1 analog output and removable terminal;

dEU is the speed deviation fault. Set the speed and detect the speed deviation. After the detection time is exceeded, the inverter will stop reporting the dEU fault. The reason may be that the load is too heavy or the rotor is blocked, which causes the speed deviation to be too large. It is necessary to check the load condition, extend the speed deviation detection time, and adjust the speed loop PI parameters according to the control mode to increase the reduced output torque.

Sleep and wake-up function, constant voltage control, constant temperature control, component maintenance, hardware lack phase detection, phase sequence detection, fan overload protection, fan current imbalance protection, etc.
