V/f OLV/PM OLV/PM EZOLV
Sets the deceleration time during Speed Search operation. Set the length of time to
decelerate from the maximum output frequency to the minimum output frequency.
Note:
When A1-02 = 8 [Control Method Selection = EZOLV], this parameter takes effect
only in Expert Mode.
V/f OLV/PM EZOLV OLV/PM
Sets the ratio used to reduce the V/f during searches to reduce the output current during
speed searches.
V/f OLV/PM EZOLV OLV/PM
Sets the Speed Search delay time to activate a magnetic contactor installed between the
drive and motor.
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 the motor rated current. Usually it is not necessary to change this setting.
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 EZOLV OLV/PM
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 EZOLV OLV/PM
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.
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
Uses the quantity of voltage in the motor to automatically switch the search method within
the type of speed measurement.
Note:
• 208 V class at 100% = 200 V
• 480 V class at 100% = 400 V
V/f OLV/PM OLV/PM EZOLV
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.
V/f OLV/PM EZOLV OLV/PM
Sets the direction of Speed Search to the direction of the frequency reference or in the
motor rotation direction as detected by the drive.
0 : Disabled
1 : Enabled
Note:
• Refer to page
146 for information about the initial value of b3-14 that applies when
you set these parameters:
–A1-02 = 0, 8 [Control Method Selection = V/f, EZOLV]
–E9-01 = 0 [Motor Type Selection = Induction (IM)]
–b3-24 = 1 [Speed Search Method Selection = Speed Estimation Speed Search]
• The initial value of b3-14 is 0 when you set these parameters:
–A1-02 = 0, 8
–E9-01 = 0
–b3-24 = 2 [Current Detection 2]
• Refer to page
146 for information about the initial value of b3-14 that applies when
you set these parameters:
–A1-02 = 8 [EZOLV]
–E9-01 = 1, 2 [Permanent Magnet (PM), Synchronous Reluctance (SynRM)]
• When you change A1-02, b3-24, and E9-01, also set b3-14.
V/f OLV/PM EZOLV OLV/PM
Sets the current level for the search retry function in Speed Estimation Speed Search as a
percentage where drive rated current is a setting value of 100%.
