Explosion countermeasure

We do not offer an explosion-proof type of vector inverter. More Details >>

Torque control accuracy

Since the torque control accuracy is influenced by change of motor temperature:- Standard product???±5% (at 75 deg C) ±0.5%/deg C of rated torque- Combinatio... More Details >>

Motor characteristics at low input voltage

Since the dedicated motor is designed with the rated voltage of approximately 320 V, it can produce sufficient torque for the input voltage of 380 V. Therefo... More Details >>

I want to drive other manufacturer's motor with PG

You can drive the motor with the FR-V240E-5.5K. However, the following conditions apply: - You need to perform auto tuning because the motor's circuit consta... More Details >>

Structures of dedicated motor

We offer the following: <<Dedicated motor model variation>>- With standard legs (SF-VR__)5.5 kW, 7.5 kW, 11 kW, 15 kW, 18.5 kW, 22 kW, 30 kW, 37 ... More Details >>

Applicable motors

In addition to the dedicated motor (SF-VR series), the SF-JR series motor with an encoder can be used. You can also use a standard motor by combining it with... More Details >>

Encoder cable length restriction

If the cable length is longer than 100 m, speed may not be read correctly due to voltage drop and waveform deformation of the encoder signal. Therefore, use ... More Details >>

Inverter current characteristics

In general, relationship between T (torque), K (constant), V (voltage), I (current), and F (frequency) is expressed as "T = K × (V/F) × I". Since (V/F) is co... More Details >>

Speed control range

1:1500 when using a vector control dedicated motor. Continuous 100% torque operation and short-time 150% torque operation are possible even at 1 rpm. Continu... More Details >>

Coasting to stop method

Use Pr.17 (Input terminal assignment) to assign MRS to the terminals DI1, DI2, and DI3. More Details >>
