  • Page 13: Wiring

    Wiring (1) Use twisted pair shield cables (0.2 mm or larger) to connect the FR-A8AP and position detector. For the wiring to the terminals PG and SD, use several cables in parallel or use a thick cable, according to the wiring length. To protect the cables from noise, run...
  • Page 14 (2) Wire the shielded twisted pair cable after stripping its sheath to make its cables loose. Also, protect the shielded cable of the shielded twisted pair cable to ensure that it will Shield not make contact with the conductive area. (perform protective treatment) Sheath Strip off the sheath for the below length.
  • Page 15 • When one position detector is shared between FR-A8AP and CNC (computerized numerical controller), its output signal should be connected as shown below. In this case, the wiring length between FR-A8AP and CNC should be as short as possible, within 5 m.

    Specifications ±1.5° Repeated positioning Depends on the load torque, moment of inertia of the load or orientaion, creep speed, position loop switching accuracy position, etc. Encoder-mounted shaft speed (6000 r/min with 1024 pulse encoder). Permissible speed The drive shaft and encoder-mounted shaft must be coupled directly or via a belt without any slip. Gear changing shafts cannot be applied.
  • Page 26: Encoder Feedback Control

    ENCODER FEEDBACK CONTROL Mount FR-A8AP to an FR-A800 series inverter to perform encoder feedback control under V/F control or Advanced magnetic flux vector control. This controls the inverter output frequency so that the motor speed is constant to the load variation by detecting the motor speed with the speed detector (encoder) to feed back to the inverter.
