The rated current and motor capacity differ depending on the inverter capacity. Refer to the inverter rated specifications

The initial value for the FR-A860-00027 is set to the 85% of the inverter rated current.
• Setting Pr.292 Automatic acceleration/deceleration = "5 or 6 (lift mode)" will change 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 PWM
frequency automatic switchover.
• To use the FR-A860-01080 in the LD and SLD ratings, a DC reactor corresponding to the applied motor is required.
• Setting the LD or SLD rating to the FR-A860-01080 changes their parameter setting increments and setting ranges in the
same way as for the FR-A860-01440 or higher. For example, the setting increment and the setting range of Pr.9 will change
from "0.01 A" to "0.1 A" and from "0 to 500 A" to "0 to 3600 A". For the setting of each parameter, refer to the parameter list
(on page 96).
