Usually we provide 7-inch HMI, with 10-inch and 4.3-inch options.
Third-party HMI can be connected to GD300-21 through Modbus RTU communication. The communication protocol in the manual is open to customers, but the HMI program needs to be configured by the customer.
If the power indicator is on, the keypad does not display, the possible causes of the failure:
1. The power supply of the driving power board is damaged or there is a short circuit;
2. The keypad wire is not in good contact or the keypad is burnt out;
3. The main control board is damaged;
If the power indicator is not on, the possible causes of the failure are as follows:
1. No input power;
2. The fuse is broken;
3. The rectifier bridge is broken.
Startup comfortability can be adjusted by setting the following function codes: P01.01, P01.03, P09.09, P09.10, P09.11, P03.00, P03.01, and P08.05. If the analog weighing equipment is used, startup pre-torque compensation must be adjusted. For details, refer to the descriptions of the function codes.
Stop comfortability can be adjusted by setting the following function codes: P09.15, P09.16, P03.00, P03.01, and P08.04.
High frequency inverter has small volume, high efficiency, no isolation transformer,light weight.
Grid frequency inverter with power frequency isolation transformer, the main characteristics are strong overload capacity and load impact resistance, high reliability, but the disadvantages are large size, low efficiency and high cost.
If the load is inductive load such as motor with greater impact, it is recommended to select power frequency off grid inverter; if the load is resistive load with less impact, it is recommended to select high-frequency off grid inverter. BN series belongs to power frequency off grid inverter.
Yes, non-standard software needs to be customized. Note that the three-phase 220VAC current is nearly twice as large as the 380VAC current, so it needs to be used at reduced power.
GD5000 input power factor ≥0.97.
The maximum power of GD3000/1140V product is 1000kW, and the maximum power of GD3000/3300V product is 2500kW
No, GD100-PV can only drive pump, its output is not sine waveform. If need supply to house application need to choose solar inverter.
