Mitsubishi Electric FR-A820-00046 Instruction Manual page 901

Parameters
● Setting procedure
Set the rated motor voltage in Pr. 19 "Base frequency voltage".
(No function at the setting of "9999" or "8888".)
Set Pr. 71 "Applied motor" = "2" (adjustable 5 points V/F).
Set frequency and voltage to be set in Pr. 100 to Pr. 109.
CAUTION:
E
Make sure to set this parameter correctly according to the motor used. Incorrect setting may
cause the motor to overheat and burn.
NOTES Adjustable 5 points V/F will become enabled at the time of V/F control.
At the time of Pr. 19 Base frequency voltage = "8888, 9999", setting of Pr. 71 = "2" cannot be made.
When setting Pr. 71 = "2", set the rated motor voltage in Pr. 19.
Read only error (
Set each point for Pr. 100 to Pr. 109 (frequency, voltage) within the range of Pr. 3 "Base frequency"
and Pr. 19 "Base frequency voltage".
When Pr. 71 = "2", Pr. 47 Second V/F (base frequency) and Pr. 113 Third V/F (base frequency) will
not function.
When Pr. 71 = "2", electronic thermal O/L relay will make calculations assuming a standard motor.
By simultaneously using Pr. 60 "Energy saving control selection" and the adjustable 5 points V/F,
further energy saving effect is expected.
The Pr. 0 "Torque boost" and Pr. 12 "DC injection brake operation voltage" settings are automati-
cally changed according to the Pr. 71 setting. (Refer to page 5-455.)
