 Main Circuit Connector Specifications (CNA)
*1 Single-phase should connect to L1 and L3.
 Motor Connector Specifications (CNB)
*1 Do not short B1 and B2. Doing so may result in malfunctioning.
Precautions for Correct UsePrecautions for Correct Use
• Tighten the frame ground screw to a torque of 0.7 to 0.8 N·m (M4).
• If you are connecting an External Regeneration Resistor, set the Regeneration Resistor
Selection servo parameter object (3016 hex).
