*1 The rated current differs according to the inverter capacity. Refer to rated specifications (page 432).
CAUTION
⋅
When Pr. 570 = "0 or 1", Pr. 260 PWM frequency automatic switchover becomes valid. (Refer to page 279.)
⋅
When using the FR-A720-02150 with LD or SLD set, always use a DC reactor (option FR-HEL-75K).
⋅
When using the FR-A740-01100 with LD or SLD set, always use a DC reactor (option FR-HEL-H90K).
(2) Precautions for the FR-A720-02150 (FR-A740-01100) or less and FR-A720-02880 (FR-
A740-01440) or more
If Pr. 570 is set to "0 (SLD) or 1 (LD)" when using FR-A720-02150 (FR-A740-01100), specifications of the inverter
change to that of the FR-A720-02880 (FR-A740-01440). Setting change of Pr. 570 is made valid after inverter reset
and all parameter clear.

For example, when using the FR-A740-01100, 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.)
