Which is the recommended digital counter?

We recommend the following digital counter: (Connect it between the terminals FM and SD.) Manufacturer: KOYO ELECTRONICS INDUSTRIES CO., LTD.Model: TC-41 More Details >>

Output voltage

The output voltage is approximately 300 VDC for the 200 V class and approximately 600 VDC for the 400 V class. 　The output voltage fluctuates due to fluctuat... More Details >>

Difference from general-purpose inverter

In general, both are inverters using the same control method, however, the inverter speed controller limits functions compared with the general-purpose inver... More Details >>

CC-Link

The FR-A7NC is required. ("FR-A7NC-E kit" for the FR-E700 series. The FR-E700-NC CC-Link communication type does not require an option.) More Details >>

FR-Configurator

No. You cannot connect it to multiple inverters.You can only connect a single personal computer to a single inverter via USB. More Details >>

Auto tuning

Check if any device is connected to the inverter's external terminal.In particular, check if MRS and SD are short-circuited.If they are short-circuited, open... More Details >>

Output frequency monitor value

When running the inverter after auto tuning, the frequency setting value is increased by the amount of the motor slippage, resulting in a higher monitor valu... More Details >>

CC-Link

You cannot monitor the running frequency and conveyor speed (machine speed) simultaneously.The inverter does not have a function to output them simultaneously. More Details >>

External wiring for CC-Link operation

For the combination of the FR-A500 + FR-A5NC, Pr.338 and Pr.339 are used to specify whether the external signals or CC-Link commands are used to set the runn... More Details >>

FR-A500 main circuit wire types

Since the UL standard defines to "Use copper wires (rated at 75?C)", we also recommend the same type of copper wire. More Details >>
