Observe the following precautions during wiring:
Note 1: Remove the jumper between terminals
and D of the servo drive before connecting
a regen resistor.
Note 2: CN3 and CN4 are two same communication ports, which can be used at random.
Note 3: For the single-phase 220 V servo drive, the main circuit terminals are L1 and L2.
Never wire the reserved terminal.
