Automatic overload control of inverter
The inverter has the current limit function. This automatically controls the frequency so that the preset current value may not be exceeded. (Note that the m... More Details >>
Connection with personal computer
Connection method for the A500 and E500 is shown in the figure below. The figure is given in an Excel file. Figure 1 More Details >>
Pr.133 can be written.Since the data code numbers of parameters are duplicate, target parameters are switched by link parameter extended setting.You can acce... More Details >>
Using the inverter's input terminal, you can use up to 15 speeds.This function is supported by the current 500 series products (A500, F500, E500, and S500).U... More Details >>
The inverter does not have a function to limit the current at 0 Hz.Although it has the DC injection brake, it is intended to improve the braking capability b... More Details >>
Current value on input side and outpu...
1. When slight imbalance (approximately 5%) is present with the inverter power supply voltage, the inverter input current can get imbalanced significantly. I... More Details >>
Inverter circuit breaker selection
Since the inverter leakage current is in proportion to the switching voltage of the transistor of the main circuit, the leakage current for the 400 V system ... More Details >>
1. To perform emergency stop, it is recommended to have the motor coast and stop it using a mechanical brake.In this case, the output stop (MRS) signal is in... More Details >>
Digital input and maximum frequency
1. Pr.1 and 18 limit the output to 120 Hz. Use Pr.18 to change the maximum frequency. 2. If you want to output the binary input as is, setting Pr.304 = 1 (Bi... More Details >>
Speed change due to power supply volt...
1. The output frequency satisfies the "control specification/frequency precision" even when the power supply voltage changes, but the output voltage cannot r... More Details >>
