Delta VFD-B is a series of variable frequency drives (VFDs) manufactured by Delta Electronics. VFDs are used to control the speed of an electric motor by adjusting the frequency of the power supplied to the motor. The VFD-B series is designed for use with standard three-phase asynchronous motors and can be used in a variety of industrial applications such as conveyors, pumps, fans, and machine tools.

The VFD-B series offers a range of features such as advanced control algorithms, built-in PLC function, and a user-friendly interface for easy setup and operation. The drives also have built-in protection functions such as overvoltage, undervoltage, overcurrent, and overheating protection to ensure safe and reliable operation.

The VFD-B series is available in a variety of power ratings and voltage ranges to meet the needs of different application. It is also equipped with communication options such as RS485, Ethernet, and USB for integration with other devices and systems.

02.00: Delta VFD b that uses a digital keypad or other inputs to set a "Master Frequency Command" The different options listed appear to be various methods of inputting this command, including using a keypad, analog voltage or current signals, or serial communication.

Here is a summary of the different options:

    00: This option allows the user to input the Master Frequency Command using the digital keypad or multi-function inputs. The last used frequency is saved.
    01: This option uses an analog voltage signal between 0 and 10 volts from an AVI input to set the Master Frequency Command.
    02: This option uses an analog current signal between 4 and 20 milliamps from an ACI input to set the Master Frequency Command.
    03: This option uses an analog voltage signal between -10 and +10 volts from an AUI input to set the Master Frequency Command.
    04: This option uses RS-485 serial communication with a RJ-11 connector to input the Master Frequency Command. The last used frequency is saved.
    05: This option also uses RS-485 serial communication with a RJ-11 connector to input the Master Frequency Command, but the last used frequency is not saved.
    06: This option allows for the combined use of a master and auxiliary frequency command, with more information available in parameters 02-10 to 02-12.

02.01:  "Source of First Operation Command" for a VFD-B or system. This command likely initiates the device's operation, and the different options refer to how the command can be inputted.

Here is a summary of the different options:

    00: This option uses the digital keypad (PU01) to input the First Operation Command.
    01: This option uses external terminals to input the First Operation Command, with the keypad STOP/RESET function enabled.
    02: This option also uses external terminals to input the First Operation Command, but with the keypad STOP/RESET function disabled.
    03: This option uses RS-485 serial communication with a RJ-11 connector to input the First Operation Command, with the keypad STOP/RESET function enabled.
    04: This option uses RS-485 serial communication with a RJ-11 connector to input the First Operation Command, but with the keypad STOP/RESET function disabled.

    01-09 Accel Time 1 0.01 to 3600.0 sec 10.0: This parameter specifies the acceleration time for the device's first acceleration phase. The range for this parameter is from 0.01 to 3600.0 seconds, and the default value is 10 seconds. This means that when the device is started or commanded to accelerate, it will take the specified amount of time to reach its maximum speed for the first acceleration phase.
    01-10 Decel Time 1 0.01 to 3600.0 sec 10.0: This parameter specifies the deceleration time for the device's first deceleration phase. The range for this parameter is from 0.01 to 3600.0 seconds, and the default value is also 10 seconds. This means that when the device is commanded to stop or slow down, it will take the specified amount of time to come to a complete stop or reach its minimum speed for the first deceleration phase.
