Precautions
• Do not install a power capacitor, surge killer, or radio noise filter (optional FR-BIF) on the servo amplifier output side.
• To avoid a malfunction, connect the wires to the correct phase terminals (U/V/W) of the servo amplifier and the rotary servo
motor.
• Do not use the 24 V DC interface power supply for the electromagnetic brake. To prevent malfunction, use the power
supply designed exclusively for the electromagnetic brake.
