Stop-on-contact control

1. You can implement stop-on-contact.2. When implementing stop-on-contact, use the inverter to decelerate the motors to reduce the impact upon stop-on-contac... More Details >>

Inverter control power supply

To supply power via R1 and S1, 60 VA or higher is necessary for 22K or lower and 80 VA or higher is necessary for 30K to 55K.Note that the rush current of ap... 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 >>

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 >>

Installing magnetic contactor on input side of inverter

Basically, there is no difference between the A200 and A500. For safer use, from the A500, it is recommended to completely shut off the power supply by turni... More Details >>

What happens if reset occurs during operation?

This is because when the inverter restarts while the motor is coasting, an overcurrent trip can occur during the restart process. However, the recent types o... More Details >>

400 Hz output setting

Change Pr.18 (High speed maximum frequency) to 400 Hz.If you are using the analog command to set the frequency, calibrate the 400 Hz frequency with Pr.903. More Details >>

Fault output contact rating

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

Changing main speed at analog signal input

To change the running frequency while the frequency command is input to the terminal 2, adjust the parameters in the following steps:1. Change Pr.77 to "2".2... More Details >>

Impossible to recover after power failure

First, ensure that the parameter for automatic restart after instantaneous power failure is set correctly and then do the following:1. Check if the terminals... More Details >>
