When the built-in brake resistor is used, the regenerative brake duty is as follows:200 V 0.4K to 3.7K: 3%, 5.5K to 7.5K

The communication is established if DA, DB, and DG are connected each other.

It is fundamentally the same as the conventional model. Considering the recent safety awareness growth, we decided to st

It is possible by using the terminal A to C with the negative logic setting.

The carrier frequency for the FR-B3 is 2 kHz. For the low noise type FR-B3-N, it is 14.5 kHz.
