Win7 64 display that Windows cannot verify the digital signature of the driver required by this device. Error 052. It may be caused by the current Win7 does not support the SHA256 algorithm. You need to download a patch from Microsoft's official website. https://www.microsoft.com/en-us/download/details.aspx?id=46148 Windows6.1-KB3033929-x64.msu, after intall update, then install the cable driver, will slove the 052 error.

The A2/B2 terminal on the GD350A PG card can accept pulse input as a speed reference. A2- connect to Y0, B2- connect to Y1. Connect A2 + and B2 + to PWR of PG card, and connect PGND to COM0 of PLC, set P21.01=1、2、3 refer to PLC pulse output formate.

The COM of the inverter is connected to the COM of the PLC, the HDO is connected to the X input of the PLC, and the +24V of the PLC is connected to S/S. Note that the PLC X input support high pulse input function refer to PLC manual.

When the Y output of the IVC series is connected to the HDI of the GD series VFD, the 24v power supply of the PLC is required. The PLC Y output connect to HDI(VFD), COM0 (PLC) connect to COM(PLC), and +24V(PLC) connect to COM terminal(VFD). In this connection mode, VFD HDI can read the pulse output of PLC.

The output cable of the low-voltage inverter must be equipped with an output reactor after it exceeds 50 meters. Our standard plus output reactor specifications can support 50-150m according to 1% voltage drop. If it exceeds 150m, need to choose 5% voltage drop output reactor,  which can support 150-500m(need to contact our technicians about the 5% reactor specification). For more than 500m, a sine wave filter is necessary.

Harmonic THD (Total Harmonic Distortion) is divided into voltage harmonics and current harmonics, as well as input and output terminals. The general customer is concerned about the current harmonic data at the input. According to  low-voltage general-purpose VFD (diode rectification), the current harmonic input terminal THDi is 35-40%. After adding an input reactor, the THDi <20%.

In the fault record interface of HMI, the date, time and fault type of historical faults will be recorded in detail. It is convenient for customers to view and analyze the cause of failure.

Connect the blocking signal to the S2~S5 digital input terminals, set the corresponding blocking signal function in P05.02~P05.05, and at the same time, it can be set as a normally open or normally closed signal.

In the motor parameter setting interface, switch the motor type to synchronous motor, then input the motor parameters according to the motor nameplate, and then perform the motor parameter autotunning. Usually this setting is sufficient. If the motor does not run well after starting, you need to fine-tune the control parameters according to the manual.
