UL standard certification number

The UL standard certification numbers (UL Listing Card No.) of the FR-E500, FR-A500, and FR-A200 are as follows: FR-A200 series??????E131592FR-A500 series???... More Details >>

Inverter input power supply

Square wave input is not recommended since it can cause failures (for example, damage the diode bridge). More Details >>

Pulse train output of terminal FM

Under Advanced magnetic flux vector control, the output frequency varies due to slip compensation. This may cause the output frequency monitor value to chang... More Details >>

Motor retention at 0 Hz

The inverter does not have a function to limit the current at 0 Hz.Although it has the DC injection brake, it is intended to improve the braking capability b... More Details >>

Auto tuning, tuning mode

The FREQROL-A200 has magnetic flux vector control in addition to the conventional V/F control. Magnetic flux vector control controls the motor with higher ac... More Details >>

Current value on input side and output side

1. When slight imbalance (approximately 5%) is present with the inverter power supply voltage, the inverter input current can get imbalanced significantly. I... More Details >>

Real sensorless vector control

For tuning of a single motor with no load, set Pr.96 to "101". When a load is connected, set Pr.96 to "1" (without motor rotation). Since Real sensorless vec... More Details >>

FR-A800-E

There are some restrictions compared to the FR-A800 (RS-485 communication type). For example, the FR-A8TR is unavailable, and only two option connectors are ... More Details >>

FR-F800

Yes, it does, however, it does not acquire the certification of the BACnet association standard. More Details >>

S-shape acceleration/deceleration of the FR-D700

It does not change even when General-purpose magnetic flux vector control is performed. Pr.3 is the inflection point of the S-shape. More Details >>
