Description
V/f CL-V/f OLV CLV AOLV
Sets the input method for frequency reference 2.
0 : Keypad
1 : Analog Input
2 : Modbus
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.
0 : Keypad
1 : Analog Input
2 : Modbus
3 : Option PCB
V/f CL-V/f OLV CLV AOLV
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.
1 : Disregard RUN
2 : Accept RUN
V/f CL-V/f OLV CLV AOLV
Sets drive response to a Run command when A1-02 = 3 or 7 [Control Method =
CLVector or PM CLVector]. Usually it is not necessary to change this setting.
1 : Reject RUN
2 : Accept RUN
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, and Zero Servo.
Note:
This parameter is available when b1-03 = 0 [Stopping Method Selection = Ramp-
>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 zero speed control at stop in CLV,
AOLV, or CLV/PM.
V/f CL-V/f OLV CLV AOLV
Sets the DC Injection Braking Time at stop. Sets the zero speed control at stop in CLV,
AOLV, or 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 [Mot 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.
