Note:
When the drive cannot accurately estimate the speed after you adjust this parameter, use Current Detection Speed Search.

During Speed Estimation Speed Searches, when the speed estimation value aligns with the minimum output
frequency, increase the setting value in 0.1-unit increments. The limit of the output current during speed search is
automatically the drive rated current.

If the drive detects ov [DC Bus Overvoltage] when you restart the motor, increase the setting value.
Note:
When A1-02 = 8 [Control Method Selection = EZOLV], the default setting is 1.00 and the setting range is 1.00 - 1.10.

V/f OLV/PM EZOLV OLV/PM
Sets the level of current that flows to the motor during Speed Estimation Speed Search as a
coefficient of E2-03 [Motor No-Load Current] or E4-03 [Motor 2 Rated No-Load Current]. Usually
it is not necessary to change this setting.
V/f OLV/PM OLV/PM EZOLV
Sets the proportional gain for the automatic current regulator during Speed Estimation Speed Search.
Also adjusts speed search responsiveness. Usually it is not necessary to change this setting.
V/f OLV/PM OLV/PM EZOLV
Sets the integral time for the automatic current regulator during Speed Estimation Speed Search. Also
adjusts speed search responsiveness. Usually it is not necessary to change this setting.
V/f OLV/PM OLV/PM EZOLV
Sets the gain to correct estimated frequencies from Speed Estimation Speed Search.
V/f OLV/PM EZOLV OLV/PM
Uses the quantity of voltage in the motor to automatically switch the search method within the type
of speed measurement.
V/f OLV/PM EZOLV OLV/PM
Sets the minimum current detection level during Speed Search. If the drive does not do Speed
Estimation, increase this setting in 0.1-unit increments.
