We do not offer a replacement product for the FR-BOL (noise reduction reactor). Since the FR-A100E is a low-noise type inverter, the motor noise is suppressed and you do not need the FR-BOL. Note that, since the FR-A100E uses high carrier frequency sine wave PWM control, noise and leakage current increase compared to the FR-Z100. If noise or leakage current occurs, lower the carrier frequency (Pr.72) to the same level as the FR-Z100 (approximately 1 kHz) and use the FR-BOL. Also, refer to our noise data sample. Figure 1
