Stall pre- 0: Disabled (Runs as set. With
vention a heavy load, the motor may
selection stall.)
during run- 1: Deceleration time 1 (the
ning deceleration time for the
L3-05 stall prevention function is
C1-02.)
2: Deceleration time 2 (the
运行中防失
deceleration time for the
速选择
stall prevention function is
C1-04.)
Stall pre- Effective when L3-05 is 1 or 2.
vention Set as a percentage of the
level dur- Inverter rated current.
L3-06 ing running Usually setting is not necessary.
The factory setting reduces the
运行中防止 set values when the motor

stalls.
Overvolt- 0: Disabled
age inhibit 1: Enabled
selection Used to enable or disable the
function for inhibiting main cir-
cuit overvoltages by reducing
the regenerative torque limit
L3-11 according to the main circuit
overvoltage level.
OV 抑制功能
If this function is enabled,
选择
when the main circuit voltage
rises, operation will be per-
formed with the regenerative
torque less than the set value.
Overvolt- Sets the main circuit voltage
age inhibit level for which the regenerative
voltage torque limit is restricted to 0.
level Usually, there is no need to
L3-12 change this setting. If main cir-
cuit overvoltages occur even
OV 抑制电压
with the overvoltage inhibit

function enabled, reduce this
setting.
* 1. The setting range for flux vector and open-loop vector 2 controls is 0 to 2.
* 2. These values are for a 200 V Class Inverter. For a 400 V Class Inverter, double the values.
Reference Detection: L4
User constants for the reference detection function are shown in the following table.
