Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the input method for Run Command 2 when the user switches the control circuit
terminals ON/OFF to change the Run command source.
0 : Keypad
1 : Digital Input
2 : Memobus/Modbus Communications
3 : Option PCB
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets drive response when energizing a drive that has an external Run command. Set this
parameter in applications where energizing or de-energizing the drive enables the Run
command.
0 : Disregard Existing RUN Command
1 : Accept Existing RUN Command
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the deadband time for MFDIs.
Description
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the frequency to start DC Injection Braking or Short Circuit Braking.
Note:
This parameter is available when b1-03 = 0 [Stopping Method Selection = Ramp to
Stop].
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the DC Injection Braking current as a percentage of the drive rated current.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the DC Injection Braking Time at stop.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the DC Injection Braking Time at stop.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets how much current the drive injects when DC Injection Braking at Start starts
(Initial Excitation) as a percentage of E2-03 [Motor No-Load Current].
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the Short Circuit Braking time at start.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the Short Circuit Braking time at stop.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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)]
Description
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the Speed Search at Start function where the drive will perform Speed Search with
each Run command.
0 : Disabled
1 : Enabled
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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.
