ST300 Series Mini Type VFD 220V 1 Phase Input Frequency Inverter
In order to meet the needs of customers, Jiesheng's engineers have developed a new economical product -
ST300 series. The volume becomes smaller, which is conducive to the rational distribution of electric box space
and avoid crowding, reduce the overall temperature rise of electric cabinet and prolong the service life of products.
Product feature of frequency inverter
Structural Design
1. Independent air duct for heat dissipation, effectively isolating pollutants from inside.
2. Using 4-layer precision PCB board and a new generation of IGBT module technology, and mostly using IC
integrated electronics.
3. The volume and weight of new generation inverters is lighter, saving installation space.
Software Design
1. ST310 inverter control modes include:
– V/F mode
0: straight line V/F
1: Multi-stage V/F
2: 1.2, 1.4, 1.6, 1.8, 2.0 powers
3: V/F separation method
2. Overload capacity: 150% for 60 sec, 180% for 10 sec, 200% for 0.5 sec.
3. The drives adopt a new software speed tracking algorithm, which have low impact on current and voltage when tracking,
also have the accurate tracking speed.
4. Maximum frequency of 3000 Hz, can be used in different machines. They have been successfully applied to chemical,
metallurgy, machine tools, woodworking, textile, and many other industries.
Hardware Design
1. Full protection function. IGBT through protection, current abnormal protection, over-current and over-voltage protection etc.
2. Wide voltage design of input power supply, works normally between 220V-380V AC.
Humanized Design
1. Multiple sets of motor parameters can be customized.
2. Provide parameters for four failure records.
3. The whole series is equipped with a 1/1 scale paper shell template for mounting holes, so as to realize more convenient and
fast electrical cabinet installation.
4. The fan partition is pull-out and detachable, and the fan can be taken out directly, which is convenient for daily maintenance.
Use of operation panel of frequency inverter
| Mark | Key Name | Function |
| MENU | Program/ Exit key | 1. Enter or exit the programming state 2. Modify the data and abandon the storage 3. Switch fault display to stop/running parameter with the SHIFT key, press MENU to switch back to fault display state |
| ENT | Identify key | 1. Edit function code parameters 2. Data storage confirmation 3. View the single group of parameters circularly |
| SHIFT | The shift key | 1. Move the editing bit of function parameters 2. Move the data editing bit 3. Switch the display parameters of the operation panel under shutdown/running state |
| Knob+ | Add keys clockwise | 1. The number of selected bits of the function code is increased 2. The selected bit of parameter value increases 3. In shutdown/operation state, the frequency value increases |
| Knob- | Counterclockwise decrease key | 1. The serial number of the function code is reduced 2. The selected bit of parameter value decreases 3. The frequency value decreases under shutdown/running state |
| RUN Stop | Run, Stop and reset keys | 1. Long press the 3S operation panel to start the driver in the given mode 2. Long press 3S to set parameters, and then start the driver for parameters self-learning 3. Press the button for 1S to report the fault and reset the fault after abnormal shutdown 4. Press for 1S to control the drive shutdown under the given mode of operation panel operation command |
