Note 1. This parameter cannot be changed during operation.
Note 2. The default setting varies with the Inverter’s capacity. The setting for 200-V class, 0.4-kW In-
verters is shown.
•
This setting is used with the speed search and DC braking functions.
•
Set the time required for the leakage voltage to dissipate. Increase the setting if an overcurrent (OC)
occurs when the speed search or DC braking function starts.
•
This setting is valid for speed searches performed after a momentary power loss and regular speed
searches.

Note This parameter cannot be changed during operation.
•
Set the time allowed for the normal voltage to be restored after completion of the speed search.
•
For a 200-V class Inverter, this is the time in seconds for voltage to be restored from 0 VAC to 200 VAC.
For a 400-V class Inverter, this is the time in seconds for voltage to be restored from 0 VAC to 400 VAC.
•
This setting is valid for speed searches after a momentary power loss, regular speed searches, the
voltage changes with energy-saving control, and the voltage changes with baseblock clearing.

Note 1. This parameter cannot be changed during operation.
Note 2. The values in parentheses are for 400-V class Inverters.
•
Normally it isn’t necessary to change this setting.
•
Use this parameter when you want to add an AC reactor and lower the main circuit under-voltage
detection level. Be sure to set a main circuit DC voltage value (V) that will detect a main circuit under-
voltage.

Stall Prevention Function Settings (L3)
A stall occurs if the rotor cannot keep up with the rotating magnetic field on the motor
stator side when a large load is applied to the motor or a sudden acceleration/decelera-
tion is performed.
In the 3G3FV, stall prevention functions can be set independently for accelerating, run-
ning, and decelerating. (Some functions are restricted depending on the control mode.)
