How to wire the operation control loop of the inverter? How many volts is the voltage?

The power supply should be connected to the R, S, and T terminals at the input end of the inverter, and must not be connected to the output terminal of the inverter (U, V, W), otherwise the inverter will be damaged. After wiring, the fragmented cords must be cleaned, the fragmented wires may cause abnormalities, malfunctions and malfunctions, and the inverter must be kept clean at all times. When punching holes in the console, be careful not to allow fragments, powders, etc. to enter the inverter.

Do not connect anything other than the recommended braking resistor option between terminals + and PR, or never short circuit. Do not install power capacitors, surge suppressors, and radio noise filters on the output side of the inverter. Failure to do so will result in drive failure or damage to capacitors and surge suppressors.

Please provide the transformer model, main circuit or control circuit?

Wiring of the main circuit of the inverter: (R, S, T) are the power supply, and the output terminals of the inverter (U, V, W) are connected to the motor respectively.

If the control loop generally wants the motor to rotate, use an intermediate relay to input the two points, the control contact input to the common end and the forward rotation start are respectively connected to the normally open contact of the intermediate relay, when the intermediate relay is energized, the motor is rotated, the power is lost, and the motor stops.

Inverter parameter setting: common parameters include inverter frequency setting, operation operation, maximum frequency, basic frequency, rated voltage, maximum output voltage, acceleration time, deceleration time, DC braking start frequency, DC braking time, starting frequency value, starting frequency holding time, stop frequency, data protection, function description, LCE monitoring, reverse rotation inhibition, thermal relay current, etc. As long as it is set according to the inverter of different manufacturers, it is OK

Explanation of the inverter failure**. Inverter FR-F700 fault** for reference:

1) FN – Inverter fan failure.

2) Overcurrent tripping during acceleration.

3) Inverter overload tripping (electronic overcurrent protection).

4) The heat sink is overheated.

5) Instantaneous power outage.

6) Insufficient voltage.

7) Enter the missing phase.

8) Output phase loss.

9) External thermal relay action.

10) The power output is short-circuited.

11) The power supply of the operation panel is short-circuited, and the power supply of RS-485 terminals is short-circuited.

How to wire the inverter needs to be determined according to the specific function that needs to be realized, and there is a wiring schematic diagram in the inverter manual, according to this, there will basically be no problem ......

The control line should be connected according to the actual use situation, generally FWD is the positive transmission, REV is the reversal, and CM is the common line. GND is the analog ground end, +10V is the analog positive end, and VIN is the analog input.

7.How to wire the inverter? How to read a circuit diagram? The technique of breaking at one point will be taught to you by hand.

What drive? How do you connect the switch that starts?

Inverters often encounter wiring problems in use, so how to wire the inverter and what should be paid attention to when wiring? Let's take a look at it.

1. The wiring principle of different brands and models of inverters is similar, and it is necessary to wire in strict accordance with the wiring drawings or instructions of the inverter.

2. There will be a high-frequency switching state in the work of the inverter, and its leakage inductance may induce a dangerous voltage on the heat sink or casing, in order to prevent electric shock, the E terminal of the inverter box needs to be grounded!

3. It is best to connect an air switch at the input end of the inverter, and the protection current value should not be too large, so as to carry out short-circuit protection.

4. The control circuit should be as short as possible, and the control circuit is too long to make the control board malfunction due to electromagnetic wave interference, which will affect the normal operation of the inverter to a certain extent.

5. In order to prevent electromagnetic interference, the input line, output line, and control line of the inverter should best use shielded cables, do a good job of grounding the shielding layer, and add filters if necessary.

6. The most important thing: you must not let the neutral line n be grounded!! Because when the inverter drags the motor in the braking state, the motor is similar to a generator at the moment, and the electric energy will be "blocked" to the main circuit board by the internal rectifier module of the inverter, and the inverter will protect and reduce the voltage under normal wiring, but if the neutral line N is directly grounded, a loop will be formed, and a large current will be generated, and the module will explode if the voltage exceeds the withstand voltage of the circuit board!

The inverter is wired correctly, refer to the manual, and it needs to be wired in strict accordance with the wiring diagram. The above explanation hopes to help you better use the inverter, Del Seaman - focus on Siemens spare parts products.

Not necessarily, there are 12V and 24V,
