Control the machines as you desire - PLC function

Inverter operation sequence customized for the machine

Inverter control such as inverter operations triggered by input signals, signal output based on inverter operation status, and monitor output can be freely customized based on the machine specifications. Control programs can be created in sequence ladders using the inverter setup software (FR Configurator2).

Application example 1 : Position error correction

The traveled distance (total number of travel pulses) of each wheel is directly read from the encoder installed at the wheel. The pulses from the two wheels are then compared, and their speed is adjusted to synchronize the wheel positions. There is no need to use an external controller to offset speed, allowing high accuracy control.

Application example 2 : Wire rope length measurement

The travel axis reads the amount of lifting/lowering movement (encoder pulse) of the lift axis to calculate the wire rope length.
The wire rope length according to the operating condition can be applied to the anti-sway control.
The lifting/lowering speed can be slowed down when the rope length reaches a predetermined value to prevent the object from colliding into the lift axis drum, etc.
