• Increased excitation is applied when the output frequency is equal to or lower than the setting in
Pr.85 Excitation current
break point
. The excitation current scaling factor at 0 Hz is set in
Pr.86 Excitation current low speed scaling factor
. Use
Pr.565 Second motor excitation current break point
and
Pr.566 Second motor excitation current low-speed scaling
factor
for the setting for using the second motor (RT signal-ON).
• When
Pr.14
= "14 or 15" and the X17 signal is turned ON, the excitation current scaling factor is switched from the value set
in
Pr.617
to the value set in
Pr.86
.
• An excitation current low-speed scaling factor set in the parameter shown in the table is used according to the
Pr.14
setting
and other conditions.
• When the SF-PR/SF-HR/SF-HRCA motor is used (
Pr.71
= "40, 43, 44, 50, 53, 54, 70, 73, or 74") and "9999" is set in
Pr.85/
Pr.86
, the predetermined setting in following the table is applied.
