Fault contact when connecting separate power supply for each control circuit

Since the inverter's fault contact is an NC contact, it does not open unless a fault occurs.Therefore, when the control power supply (and main circuit power ... More Details >>

FR-A500 main circuit wire types

Since the UL standard defines to "Use copper wires (rated at 75?C)", we also recommend the same type of copper wire. More Details >>

Single-phase power supply drive

For a single-phase 200 V power supply, you can use the FR-E520S series for up to 0.75 kW motor.If you use the three-phase 200 V power supply inverter with a ... More Details >>

Current increase at motor stop

If the current increases when the motor stops under V/F control (at low speed under a light load), the motor is considered to be in the overexcitation state.... More Details >>

Control method

When motor current is large

If the parameters related to the output voltage are not changed from the initial setting, it is unlikely that the output current at 55 Hz and 60 Hz is double... More Details >>

Concurrent monitoring of running frequency, output voltage, and output current

Add an analog output by the FR-A5AY.Monitor the three output; output AM (0 to 5 (10) V) and optional 4 to 20 mA, and 0 to 5 (10) V. More Details >>

Comparison with FR-A200E
