PLC function

In accordance with the machine specifications, users can set various operation patterns: inverter movements at signal inputs, signal outputs at particular inverter statuses, and monitor outputs, etc. Operation of the system can be customized by the inverter alone.
Parameters and setting frequency can be changed at the program. Control programs can be created in sequence ladders using the inverter setup software (FR Configurator2).

Position control

Positioning under Vector control is available.
The cumulative pulse can be monitored, enabling accurate transfer of glass or PET bottles to the filling position.

Positioning function (point table method)
Position data (target position, speed, acceleration/deceleration time) and so on can be set in the parameters.
Positioning is possible for up to 7 points.
Positioning operation is performed by selecting point table numbers with external interface signals.
Continuous positioning is possible.

PM sensorless vector control

The torque is not reduced in the high-speed range (up to the rated speed) during PM sensorless vector control as compared with operation using a stepper motor.
High-speed system operation improves the tact time.
PM sensorless vector control is available when inverters are used with PM motors. High-level control such aspositioning control is enabled without using an encoder.
The PM motor offline auto tuning enables sensorless operation of other manufacturers' permanent magnet (PM) motors. (Tuning may be disabled depending on the motor characteristics.)

Plug-in options

In addition to the existing plug-in options to add digital inputs / analog outputs and to support different communication standards, the Vector control compatible option FR-A8AP E kit is supported. Among our compact inverters, the FR-E800 inverter is the first to support Vector control.
