Description
V/f CL-V/f OLV CLV AOLV
Sets the DC Inject Braking Time at start. Configures the zero speed
control at start when using Closed Loop Vector Control, Advanced
Open Loop Vector Control, or Closed Loop Vector Control for PM.
V/f CL-V/f OLV CLV AOLV
Sets the DC Inject Braking Time at stop. Configures the zero speed
control at stop when using Closed Loop Vector Control, Advanced
Open Loop Vector Control, or Closed Loop Vector Control for PM.
V/f CL-V/f OLV CLV AOLV
Sets the amount of current injected in the beginning of DC Injection
Braking at start (initial excitation) as a percentage of the value set in
E2-03 [Motor No-Load Current].
V/f CL-V/f OLV CLV AOLV
Sets the Short Circuit Braking time at start.
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.
Description
V/f CL-V/f OLV CLV AOLV
Sets whether to execute Speed Search or not with each Run
command.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the current level that ends Speed Search as a percentage of the
drive rated output current. Normally there is no need to change this
setting.
V/f CL-V/f OLV CLV AOLV
Set the time it takes to decelerate from the maximum output
frequency to the minimum output frequency.
V/f CL-V/f OLV CLV AOLV
Configures 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
If a magnetic contactor is installed between the drive and the motor,
this parameter sets a delay time to activate the magnetic contactor
by delaying Speed Search.
V/f CL-V/f OLV CLV AOLV
Configure the amount of current that flows to the motor as a
coefficient of the motor rated current when executing the Speed
Estimation Speed Search. Normally there is no need to change this
setting.
V/f CL-V/f OLV CLV AOLV
The amount of current that flows to the motor when Speed
Estimation Speed Searches are executed is configured as a
coefficient of E2-03 [Motor No-Load Current] or E4-03 [Motor 2
Rated No-Load Current]. Normally there is no need to change this
setting.
