Mitsubishi FR-A740-00023-EC - 4.11 Frequency setting by external terminals

Adjust the output torque of the motor (current)
*1 The rated current differs according to the inverter capacity. Refer to rated specifications (page 426).
(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.)
