Note: 1. The set value (%) indicates the ratio to the rated
inverter output current.
2. If the stall prevention operation level signal input func-
tion has been selected (Pr. 22
=
"9999"), setting
"9999" in Pr. 49 will also change the stall prevention
operation level from the value of the stall prevention
operation level signal (terminal 1 input) to the set
value of Pr. 48 when terminals RT and SD are con-
nected.
3. If Pr. 49
=
"9999", setting "0" in Pr. 48 will deactivate
the stall prevention function when terminals RT and
SD are connected.
If Pr. 49
+
"9999" and Pr. 48
=
"OH, the stall prevention
operation level is 0% at or below the frequency set in
Pr. 49.

CAUTION
A
Do not set the second stall prevention operation current
too small.
If set so, torque generated will reduce.
o Pr.
50 "second output frequency detection"
Inaddition to the detected output frequencies set in Pr. 42 and
Pr. 43, the detected output frequency can be set.
By setting ' 1 5" (FU2) in any of the first to fourth digits of Pr. 40,
the signal can be output from any of the SU, ,IPF, OL and FU
terminals. The terminal signal is turned on at or above the set
frequency (the built-in transistor is switched on). (See the
section of Pr. 42 and Pr. 43.)
