Description
V/f CL-V/f OLV CLV AOLV
Sets the input method for frequency reference 2.
0 : Keypad
1 : Analog Input
2 : Memobus/Modbus Communications
3 : Option PCB
4 : Pulse Train Input
V/f CL-V/f OLV CLV AOLV
Sets the input method for Run Command 2 when the user switches the control circuit
terminals ON/OFF to change the Run command source.

1 : Digital Input
2 : Memobus/Modbus Communications
3 : Option PCB
V/f CL-V/f OLV CLV AOLV
Sets drive response when the CPU changes from de-energized to energized and there is
an active Run command. Set this parameter in applications where energizing or de-
energizing the drive enables the Run command. When the CPU stays energized during
loss of power, L2-01 [Power Loss Ride Through Select] sets operation.
0 : Disregard Existing RUN Command
1 : Accept Existing RUN Command
V/f CL-V/f OLV CLV AOLV
Sets the conditions for the drive to accept a Run command when A1-02 = 3, 7 [Control
Method Selection = CLV, CLV/PM]. Usually it is not necessary to change this setting.
0 : Reject RUN if b2-01<U1-05<E1-09
1 : Accept RUN Command at Any Speed
V/f CL-V/f OLV CLV AOLV
Sets the deadband time for MFDIs.
Description
V/f CL-V/f OLV CLV AOLV
Sets the frequency to start DC Injection Braking, Short Circuit Braking, or Zero Servo
near the end of a stop ramp.
Note:
This parameter is available when b1-03 = 0 [Stopping Method Selection = Ramp to
Stop].
V/f CL-V/f OLV CLV AOLV
Sets the DC Injection Braking current as a percentage of the drive rated current.
V/f CL-V/f OLV CLV AOLV
Sets the DC Injection Braking Time at stop. Sets the time of Zero Speed Control at start
when A1-02 = 3, 7 [Control Method Selection = CLV, CLV/PM].
V/f CL-V/f OLV CLV AOLV
Sets the DC Injection Braking Time at stop. Sets the time of Zero Speed Control at stop
when A1-02 = 3, 7 [Control Method Selection = CLV, CLV/PM].
V/f CL-V/f OLV CLV AOLV
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 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.
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)]
