Installation of new serial communication unit FR-CU03

Remove the parameter unit FR-PU03 and install there. (The installation dimensions of the FR-CU03 are the same as the FR-PU.) You can read and write parameter... More Details >>

Features of parameter unit FR-PU03

This parameter unit realizes both easy operation and advanced operation. In normal operation, you only need to use six keys for easy operation. To perform ad... More Details >>

Can I use it with the single-phase power supply?

You can use the inverter with the single-phase 200 V power supply. However, since ripple current flowing through the capacitor increases and the converter an... More Details >>

Range of carrier frequency

You can vary the carrier frequency within the range of 0.7 to 14.5 kHz, and it is initially set to 1 kHz that generates low noise and leakage current. You ca... More Details >>

Key sheet

You cannot remove the key sheet from products with the key sheet attached as a standard other than the PU operation type. When using the parameter unit FR-PU... More Details >>

Can I connect a brake resistor?

You cannot connect a brake resistor to the FR-U100 series inverter. (Use the FR-A024 series if you use the brake frequently.) More Details >>

How many inverters can be connected?

Up to 32 units can be connected. (This is because the inverter communication conforms to RS-485.) More Details >>

DIN rail installation

Unit type: SC-A□□U can be installed on the DIN rail. Box type: SC-A□□B cannot be installed on the DIN rail. More Details >>

Combination with power factor improving reactor

It cannot be combined with the power factor improving reactor. (Since the power factor is further improved by the high power factor converter, it is not requ... More Details >>

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 >>
