Meaning of OL display (2)

Yes. "OL" is displayed under speed control whenever the torque limit is reached without regard to the rated torque. More Details >>

Can I change the carrier frequency?

You can change it by changing the setting of Pr.72 (PWM frequency selection). Setting range of Pr.72: 0, 1, 2, 3, 4, 5, 6 (Initial setting is "6".) (The smal... More Details >>

Encoder signal output

It can be output by attaching the plug-in option FR-VPA, FR-VPB, or FR-VPC. Note that the output format depends on the option type. FR-VPA: Open collector ou... More Details >>

Motor wiring length

Up to 50 m. Be sure to connect the encoder cables in parallel and use the thicker cable gauge. You can extend this distance up to 100 m by using the long dis... More Details >>

Use of general-purpose servo motor

You can operate it by adjusting the motor constant by the auto tuning function. (Note that the same characteristics as operated by the servo amplifier MR-VA ... 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 >>

Small capacity vector inverter dedicated motor

We offer 5.5 kW or higher SF-VR dedicated motors and do not offer small capacity (3.7 kW or lower) motors. If you need small capacity (1.5 kW to 3.7 kW), use... More Details >>

Comparison with FR-A200E

In addition to speed control, you can also select torque control as well as you can perform position control using an option. The speed control range is as l... More Details >>
