* 3. These are values for a 200 V Class Inverter. Values for a 400 V Class Inverter are double.
Reference Detection: L4
User constants for the reference detection function are shown in the following table.
L3-11
Overvolt-
age inhibit
selection
0: Disabled
1: Enabled
Used to enable or disable the
function for inhibiting main
circuit overvoltages by
reducing the regenerative
torque limit according to the
main circuit overvoltage
level.
If this function is enabled,
when the main circuit volt-
age rises, operation will be
performed with the regenera-
tive torque less than the set
value.

Overvolt-
age inhibit
voltage
level
Sets the main circuit voltage
level for which the regenera-
tive torque limit is restricted
to 0.
Usually, there is no need to
change this setting.
If main circuit overvoltages
occur even with the over-
voltage inhibit function
enabled, reduce this setting.
