INVT standard GD5000 four-quadrant products can only produce 10KV and 6KV. However, if the customer needs 3.3,6.6 and 11KV, we can meet the customer's requirements through non-standard design.The maximum current cannot exceed 160A.

1.General connection：Pump LN connect to inverter UW.
2.Three wires connection:Remove capacitor,then connect with UVW cable,ensure resistance of UW is minimum,resistance of UV is maximum.Short connect S4&COM terminal.

GD35 support. GD300，GD350，GD600 and GD800 support, too.

There are two ways: by setting P08.39 function code or combining with sleep function. For example, set P00.05=1, P01.19=2,P05.01=1. S1 is the forward rotation (Zero speed) and S2, S3, S4 multistep speed,S1 is always bridge with the GND and the fan is always in operation. Use S1 and GND to stop the fans. P01.19 turn to 2 and the lower Hz will be 1Hz. Then the inverter when goes to 0 goes to sleep mode.

The motors, wires or inverters are damaged, the wires are not connected properly. Or the function settings are improper. For example, the setting of upper limit frequency, lower limit frequency, basic frequency and maximum frequency set incorrectly. When using external control, there are no pre-settings and other unreasonable settings.

GD100-PV is a professional photovoltaic water pump driver. The -SS2 model integrated a special single-phase pump special algorithm, which can support driving single-phase 220V pumps. Divided into two kinds of schemes, one is not to dismantle the water pump capacitor, directly connected to U and W terminals. Another solution needs to removed the water pump capacitors,connected to the UVW terminal according to the schematic diagram in the GD100-PV operating manual.Normally we suggest to remove the water pump capacitors.

GD35 with servo motor is to first understand the encoder type of servo motor, select the matching GD35 inverter model, 50Hz corresponding voltage, back EMF and pole number and other parameters. P20.11 do autp-tunning of magnetic pole position. Change P21.00 to 1 position control pulse train setting. In addition, P20.13 is changed to 0 disable, the current loop of P03.09 can be increased by about 1500. "

INVT LED keypad can use for different series.Big LED keypad and small LED keypad can't be used for each other.
Small keypad series:GD10&GD20%GD100-PV&BPD
Big keypad series:GD200A&GD300&GD35&GD350&GD350A

Overheating is a common fault. When encountering this kind of situation, we will first think about whether the cooling fan is running, whether the fan is blocked, whether the ambient temperature is too high, the inverter is not well ventilated, and the temperature detection circuit is faulty.
