Precautions for Correct Use
Precautions for Correct Use
•
Tighten the frame ground screw to a torque of 1.4 to 1.6 N·m (M5).
•
Tighten the 24-V terminal block screws to a torque of 0.4 to 0.6 N·m (M3).
•
Tighten the terminal block screws to a torque of 0.7 to 1.0 N·m (M4). Exceeding the maximum
allowable torque for terminal block screws may cause damage to the terminal block.
•
Tighten the bottom terminal block screws to a torque of 0.19 to 0.21 N·m (M3).
•
If you connect an External Regeneration Resistor, set the Regeneration Resistor Selection
servo parameter object (3016 hex).
•
Do not connect an external regeneration resistor between the B1 and NC terminals.
