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 >>

Controlling multiple VVVFs via communication from personal computer

To control multiple inverters using arbitrary signals (4 to 20 mA) simultaneously, it is recommended to connect the signals (4 to 20 mA) in series. (This doe... More Details >>

Items controllable via CC-Link

1. Not all items can be controlled. 　　- Functions that cannot be controlled JOG, AU, CS, OH, X10, X11, X12, and X16 functions (Other functions can be control... 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 >>

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 >>

Brake unit selection

Since the FR-A540-0.75K has a brake transistor for resistor regenerative driving inside the inverter, you do not need to use BU. Just remove the jumper from ... 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 >>

Term definition and advanced magnetic flux control

1. Maximum torque available for output from the motor when combined with an inverter for a short period of time (1 minute or less). 　　It depends on the contr... More Details >>
