Inverter installation interchange attachment

Use the FR-A5AT02 as the intercompatibility attachment when upgrading from the FR-A220-3.7K to FR-A540-3.7K. More Details >>

Instantaneous power failure of facilities

1. If the start signal is present when the power and communication restore, the inverter starts operation. 2. Similarly to the above, if the start signal is ... More Details >>

Pulse train output of terminal FM

Under Advanced magnetic flux vector control, the output frequency varies due to slip compensation. This may cause the output frequency monitor value to chang... More Details >>

Selection

Refer to the following points.For fan pump -> Square torqueFor general-purpose machine (for example, transport, elevation) -> Constant-torque type More Details >>

Regenerative brake resistor

The brake resistor is not built in the inverter. Purchase the optional resistor and connect it to the inverter.Inverter only (without resistor)Continuous reg... More Details >>

Clutch connection of load

Since a large load is applied to the motor when the electromagnetic clutch turns on, overcurrent may occur if the load is heavy. To ensure that the rated cur... More Details >>

Selection of high-duty brake resistor

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

Second deceleration time setting

Your suggestion is fine, but note that deceleration stop is naturally not available in case of an inverter error.In addition, considering regenerative power,... More Details >>
