Tab. 6-34: Influence of Pr. 570 on other parameters (2)
The rated current differs according to the inverter capacity.
NOTE
When Pr. 570 = "0 or 1", Pr. 260 "PWM frequency automatic switchover" becomes valid.
(Refer to section 6.19.1.)
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 all parameter
clear and inverter reset.

Tab. 6-35: Influence of Pr. 570 on the inverter specifications
Example For example, when using the FR-A740-01800, setting "0" in Pr. 570 and performing inverter
reset after all parameter clear 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.)

Parameter Setting
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.
