Is the number of writing times of the parameter memory limited?

1. The limit of the parameter writing is 100,000 times. 2. Parameter error occurs. Since the data in the ROM may be broken, the inverter may become unavailab... More Details >>

Functions available when using inverter on CC-Link

You can use the regular terminal block wire functions during CC-Link operation. 　Set Pr.338 (Operation command source) and Pr.339 (Speed command source) to e... More Details >>

Selection of high-duty brake resistor

Select the high-duty brake resistor according to the inverter capacity. More Details >>

Fault output contact rating

They are capable of a load of 5 VDC±5% and 10 mA. More Details >>

Inverter signal input speed

There is a 10 ms delay after the inverter recognizes the start command (STF OR STR) before it starts decelerating. The delay is 10 ms. A delay of 100 ms is i... More Details >>

Inverter stop-on-contact control

Use the FREQROL-A500 series inverter with the optional FR-A5NC.Then, you can implement both of stop-on-contact control and CC-Link operation. 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 >>

Operation of the motor with a brake

For the general-purpose inverter, the motor stop cannot be detected accurately because the actual motor speed from a motor is not input. In general, the RUN ... More Details >>

Countermeasure against the fault occurrence

When a CC-Link communication fault occurs, the option error (OP3) occurs on the inverter and the output is shut off, and the motor starts coasting. When usin... More Details >>

Countermeasure against oil mist

1. You cannot use the inverter in an environment where it is exposed to oil mist. 　You need to enclose the inverter in an enclosure and then install the encl... More Details >>
