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.

Name
3-phase 200 to 230 VAC (170 to 253 VAC) 50/60 Hz
Single-phase 200 to 230 VAC (170 to 253 VAC) 50/60 Hz
Normally short B2 and B3. If there is high regenerative energy, remove the
short-circuit bar between B2 and B3 and connect an External
*1 Regeneration Resistor between B1 and B2.
Phase U These are the output terminals to the Linear Motor.
Phase V
Phase W
This is the ground terminal. Ground to 100  or less.
