Note
1.The L1,L2,L3 and L1C,L2C terminals wiring method of ProNet-A5A
～
04Aservo 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-A5A
～
04A is Single-phase 200V.
3.External regenerative resistor for ProNet-A5A
～
04A is provided by customer, the model of 60W,50
Ω
resistor is
recommended.
4.Change Pn521.0 from
“1” to “0” when using the external regenerative resistor in ProNet-A5A
～
04A servo drives.
