YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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 OLV/PM AOLV/PM EZOLV
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 OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the deadband time for MFDIs.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the frequency to start DC Injection Braking or Short Circuit Braking near the end of a stop ramp.
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 AOLV/PM EZOLV OLV/PM
Sets the Short Circuit Braking time at start.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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)]
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the Speed Search at Start function so the drive will do Speed Search with each Run command.
0 : Disable
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.
