Do not short B1 and B2. Doing so may result in malfunctioning.
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 terminal block screws to a torque of 1.0 to 1.7 N·m (M5). Exceeding the maximum
allowable torque for terminal block screws may cause damage to the terminal block.
•
Tighten the fixing screw of the terminal block cover to a torque of 0.19 to 0.21 N·m (M3).
•
If you are connecting an External Regeneration Resistor, set the Regeneration Resistor
Selection servo parameter object (3016 hex).
•
Do not connect any External Regeneration Resistors between B1 and NC.
