Customizing inverter operation for each machine
- 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).

- Vector control
For example, when the inverters are used for a ceiling crane, Vector control using the encoder feedback is available for the lift axis (plug-in option required), and Real sensorless vector control is available for the travel axis and the traverse axis.
|Speed control||Speed control range||1:1500 (both driving/regeneration*1)|

|Torque control||Torque control range||1：50|
|Absolute torque accuracy||±10％*3|
|Repeated torque accuracy||±5％*3|
|Position control||Repeated positioning accuracy||±1.5°(at motor shaft end)|
|Positioning feedback pulse||Number of encoder pulses per motor rotation (Pr.369) × 4|
|Electronic gear setting||1/900 to 900*4|
|In-position width||0 to 32767 pulses|
|Error excess||0 to 400K pulses|
Products with or without this function may coexist in the market depending on the inventory and distribution conditions.
- ＊1: Regeneration unit (option) is necessary for regeneration
- ＊2: Maximum frequency × 120 / number of poles / 60 s × number of encoder pulses (before multiplied by 4)
- ＊3: When a High-performance energy-saving motor with encoder (SF-PR-SC) is used with the rated load
- ＊4: Set the electronic gear ratio in the range of 1/50 to 20. If the setting value is too small, the speed command will also be too small; while if it is too large, the speed ripple will increase.
Improving work efficiency by powerful high-speed operation
- 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.)
Accurate and stable transfer
- Position control
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.
