2.INSTALLATION
2.1 Pre-Installation Instructions
(1) Make sure that the input power of the inverter is off.
(2) When the FR-A5AP unit is used for encoder feedback control or orientation control, an encoder (motor
with encoder) and external power supply are required.
When encoder feedback control and orientation control are used together, the encoder (motor with
encoder) and external power supply are shared between these controls.
(3) When the FR-A5AP unit is fitted, the programmed operation function is made invalid.
2.2 Installation Procedure
(1) Securely insert the connector of the option unit far into the connector of the inverter. At this time, fit the
option fixing holes snugly. For the position of slot, refer to the next page. Also be sure to fit the unit into
the option fixing hook (For the FR-A500(L) series, it is available in Aug., 2000).
(2) Securely fix the two right and left places of the option unit to the inverter with the accessory mounting
screws. If the screw holes do not line up, the connector may not have been plugged snugly. Check for
looseness.
With input power on, do not install or remove the option unit. Otherwise, the inverter and
option unit may be damaged.
