*2 The rated current and motor capacity differ depending on the inverter capacity. Refer to the inverter rated specifications
*3 The initial value for the FR-A820-00077(0.75K) or lower and FR-A840-00038(0.75K) or lower is set to the 85% of the inverter rated current.
• Setting Pr.292 Automatic acceleration/deceleration = "5 or 6 (lift mode)" changes the stall prevention operation level as
shown below.

NOTE
• When Pr.570 = "0" (SLD rating), carrier frequency automatic reduction is enabled regardless of the setting in Pr.260.
• To use the FR-A820-03160(55K) and the FR-A840-01800(55K) in the LD and SLD ratings, a DC reactor, which is available
as an option, corresponding to the applied motor is required.
• Setting the LD or SLD rating to the FR-A820-03160(55K) and the FR-A840-01800(55K) changes their parameter setting
increments and setting ranges in the same way as for the FR-A820-03800(75K) and the FR-A840-02160(75K) or higher. In an
example of Pr.9, the setting increment changes from "0.01 A" to "0.1 A" and the setting range changes from "0 to 500 A" to "0
to 3600 A". For the setting of each parameter, refer to the parameter list (on

5.7.12 Using the power supply exceeding 480 V

To input a voltage between 480 V and 500 V to the 400 V class inverter, change the voltage protection level.
Pr. Name
977 Input voltage mode
E302 selection
• To use a voltage between 480 V and 500 V, set Pr.977 Input voltage mode selection = "1". The setting is applied after
a reset.
• Setting Pr.977 = "1" changes the voltage protection level to the one for the 500 V class.
• The increased magnetic excitation deceleration operation level is 740 V. Use Pr.660 Increased magnetic excitation
deceleration operation selection to select the increased magnetic excitation deceleration.)
NOTE
• Stand-alone options (except line noise filter) cannot be used when inputting a voltage between 480 and 500 V.
• The voltage protection level of the 200 V class inverters is not affected by the Pr.977 setting.
