1. How to complete the control of ATV38 and ATV58 through the operation panel?

First, in the control menu, set "LCC" to "YES" (panel operation); Enter the "LFR" parameter in the adjustment menu, press the up and down keys to adjust the given value, and complete the control of the inverter.

How can multiple ATV71/61 inverters connected to the same bus communicate with a graphical display terminal? The [Communication] menu→ [Network MODBUS] → [MODBUS Address] (ADD) set the address of each inverter. When multiple inverters are connected to the same display terminal, the terminal will actively display the inverter address. All menus can be accessed in multipoint mode, but the graphical display is not allowed to control the inverter.

Schneider inverter simple question

2. In the use of motor reactors, why is the interval required for shielded cables shorter than those of unshielded cables?

Because parasitic capacitance is generated between the shield layer and the conductor of the shielded cable, the cable should not be too long.

3. The main circuit of the high-power ATV71/61 inverter has been energized, why does NLP (main circuit not energized) sometimes prompt?

This is because there is no short wiring between the terminals PO and PA/+ connected to the DC reactor, and the main circuit cannot be supplied with power. The short-wired of the frequency conversion less than 90KW has been connected when leaving the factory, and the frequency conversion greater than or equal to 90KW needs to be short-circuited by the customer.

4. What is the function of the inverter DC reactor?

Reduce the higher harmonic interference of the input current and improve the power factor of the input power supply.

5. What is the significance of forced local operation of the inverter?

Local operation refers to the control of the terminal or display module by the inverter, and the corresponding communication control. If you want to switch between communication control and local operation, you must configure a logical input terminal as "FLO", that is, force local operation. When the input is condition 1, the local operation is forced; When the input is condition 0, the communication control is useful.
