If using an internal regenerative resistor, please short
B2 and B3. Remove the wire between B2 and B3 and
connect an external regenerative resistor(provided
by customer) between B1 and B2, if the capacity of
the internal regenerative resistor is insufficient.

Note
1.The L1,L2,L3 and L1C,L2C terminals wiring method of ProNet-02A～04A/ProNet-E-02A～04A servo drives is different
from other ProNet series servo drives. Please note the specific terminal definition while wiring.
2.The main circuit power supply of ProNet-02A～04A/ProNet-E-02A～04A is Single-phase 200V
