Winding control

As an example, you can use an inverter to feed the cord at the constant speed under dancer control using a combination of the deviation detector and deviatio... 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 >>

Installing parameter unit outside control panel

You can install the operation panel FR-DU04 (or parameter unit FR-PU04) on the enclosure surface by connecting it with the inverter via a cable.To do this, d... More Details >>

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 >>

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 >>

Fault output contact rating

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

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 >>

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 >>

Inverter

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 >>
