V/f CL-V/f OLV CLV AOLV
Sets the Short Circuit Braking time at stop.
V/f CL-V/f OLV CLV AOLV
Sets the Short Circuit Braking Current as a percentage of the motor rated current.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor rated current.
• A1-02 = 5, 6 [OLV/PM, AOLV/PM]: E5-03 [PM Motor Rated Current (FLA)]
• A1-02 = 8 [EZOLV]: E9-06 [Motor Rated Current (FLA)]
V/f CL-V/f OLV CLV AOLV
Sets the Speed Search at Start function so the drive will do Speed Search with each Run command.
0 : Disable
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the current level that stops Speed Search as a percentage of the drive rated output current.
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
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 CL-V/f OLV CLV AOLV
Sets the ratio used to reduce the V/f during searches to reduce the output current during speed
searches.
V/f CL-V/f OLV CLV AOLV
Sets the Speed Search delay time to activate a magnetic contactor installed between the drive and
motor.
V/f CL-V/f OLV CLV AOLV
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 CL-V/f OLV CLV AOLV
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 CL-V/f OLV CLV AOLV
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 CL-V/f OLV CLV AOLV
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 CL-V/f OLV CLV AOLV
Sets the gain to correct estimated frequencies from Speed Estimation Speed Search.
