*1 The rated current differs according to the inverter capacity. Refer to rated specifications (page 426).
CAUTION
⋅
When Pr. 570 = "0 or 1", Pr. 260 PWM frequency automatic switchover becomes valid. (Refer to page 272.)
(2) Precautions for the FR-A740-01800 or less and FR-A740-02160 or more
If Pr. 570 is set to "0 (SLD) or 1 (LD)" when using FR-A740-01800, specifications of the inverter change to that of the
FR-A740-02160. Setting change of Pr. 570 is made valid after inverter reset and all parameter clear.

For example, when using the FR-A740-01800, setting "0" in Pr. 570 and performing all parameter clear after inverter
reset will change the setting range of Pr. 9 from "0 to 500A" to "0 to 3600A" and the minimum setting increments
from "0.01A" to "0.1A". (Refer to the parameter list for other parameters.)

The inverter operates in the same manner as the FR-A740-02160 or more.
Parameter setting range, minimum setting increments, initial values, etc. change to those
of the 02160 or more. Refer to the parameter list for parameters whose values change.
