What happens if the supplied reactor and outside box are not used?

Harmonics cannot be suppressed (controlled) correctly and noise cannot be removed. Be sure to connect the supplied reactor and outside box to the inverter. More Details >>

Communication option

You can remove the parameter unit FR-PU02 and install the FR-CU01 there. However, since the interface for the parameter unit is used, the communication speed... 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 >>

Power supply phase sequence

No problem.The inverter converts AC power into DC power and then into AC (PWM) power output again. Therefore, it is not influenced by the power supply phase ... More Details >>

Electronic thermal O/L relay setting

Set Pr.9 to the rated current at 50 Hz or a value 1.1 times as the rated current at 60 Hz.You can specify the motor type with Pr.71 (Applied motor). For a co... More Details >>

Selection of high-duty brake resistor

Select the high-duty brake resistor according to the inverter capacity. More Details >>

Clutch connection of load

Since a large load is applied to the motor when the electromagnetic clutch turns on, overcurrent may occur if the load is heavy. To ensure that the rated cur... More Details >>

Usage

1. Changing frequency to 0 Hz(1) Set Pr.8 (Deceleration time) to 0 second.If the load is large, the stall prevention function may work to lengthen decelerati... More Details >>

FR-BSF01 wiring

The filtering effect is higher as the cable is wound more.However, if the cable is wound more than 4T on the inverter output side, since the inverter's outpu... More Details >>

All parameters returned to initial values

The parameters of the A500 series are stored in the EEPROM.The reason why all parameters returned to the initial values is considered that you may have opera... More Details >>
