L3-06
Stall prevention level
during running
x 30 to 200 % 160 B B x x
D
This setting is valid when L3-05 is set to 1 or 2.
D
Normally it isn’t necessary to change this setting.
D
Decrease this setting when the motor capacity is small compared to the Inverter capacity or stalling oc-
curs when the motor is operated with the factory setting.(Set this current value as a percentage of the
Inverter’s rated current, i.e., 100% corresponds to the Inverter’s rated current.)
Output current
Time
Output frequency
Time
The output frequency is controlled to prevent
stalling.
Deceleration rate: C1-02 or C1-04

Set these constants when outputting one of the frequency agree or frequency detection signals from a
multi-function output. Table 7.13 shows the relationship between these constants and the output signals.
