Speed fluctuation ratio

1. Speed fluctuation ratio when using the FR-V200 + dedicated motor (with an encoder) The vector inverter FR-V200 detects speed by the encoder and speed fluc... 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 >>

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 >>

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 >>

Surge voltage of 400 V inverter

No. Although the carrier frequency increases or decreases the switching count, the switching speed is the OFF-to-ON speed of the IGBT element of the inverter... More Details >>

Driving 200 V motor by 400 V inverter

A 400 V inverter does not operate when 200 V is supplied to it, therefore the motor does not rotate. A 200 V motor can be rotated by a 400 V inverter, howeve... More Details >>

Rotations per minute vary

It is considered that conditions including the power supply and noise change whether the parameter unit is connected or disconnected, influencing the analog ... More Details >>
