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 >>
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 >>
Installation clearance of inverters
Keep 1 cm or more of clearance for 3.7 K or smaller, and 5 cm or more for 5.5 K or larger.If the clearance is too small, the cooling effect is lowered. Secur... More Details >>
Coasting operation of the inverter
To use an inverter using the external contact coast to stop (to shut off the inverter's output), short-circuit the terminals MRS and SD.For CC-Link operation... 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 >>
Operation by single-phase power supply
Similarly to the FR-A220, single-phase power supply operation is possible by reducing the inverter's output current.Ensure that the output current is smaller... More Details >>
Inverter installation interchange att...
Use the FR-A5AT02 as the intercompatibility attachment when upgrading from the FR-A220-3.7K to FR-A540-3.7K. More Details >>
You can use the Hioki Memory HiCorder and clamp-on AC/DC high tester.You can observe the inverter's frequency in one of the following two methods:1. Attach t... More Details >>
Driving 200 V motor by 400 V inverter
A 400 V inverter does not operate when 200 V is supplied to it, therefore the motor does not rotate. A 200 V motor can be rotated by a 400 V inverter, howeve... More Details >>
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 >>
