Functions and parameters
The converters of the DV-300 series feature a number of functions that can be set and assigned parameters in
order to meet the requirements of the application at hand.
The device can be controlled in different ways:
- via the terminal strip
- via the keypad
- via the RS 485 serial interface
- via a bus connection (option)
The settings required are made via the Main commands and Control mode parameters in the CONFIGU-
RATION menu.
The device is supplied with a Windows
TM -based user interface software for controlling the drive and setting
parameters via the RS 485 serial interface.
The device is factory set for speed regulation with a cascade current regulation and is connected according to the
connection diagram shown on in section 4.8, “Standard connection diagrams”. Only the entry of parameters in
the START UP of the software is required for the initial commissioning of the drive. The drive is thus controlled
via the terminal strip with all parameters set via the keypad.
If functions are required that are not in the standard configuration, these can be selected and their parameters set
accordingly via the appropriate menu.
The 6KCV300TBO option card is required for expanding the standard device with programmable inputs/outputs.
Up to no. 2 6KCV300TBOs can be fitted, each providing 4 digital inputs, 4 digital outputs and 2 analog outputs.
Three analog inputs are provided on the standard device.
The converters of the DV-300 series enable reference values for the ramp and for the speed regulator to be set
in different units of measure:
- in percentages of the Speed base value
- in a unit of measure (dimension) that the user can define using the factor function, e.g. as speed in m/s.
According to which one is set as last the other will be updated. This means that the other reference value is
overwritten with the current value.
A freely selectable password 1 prevents the operation of the converter by unauthorized persons. It is entered in
the form of a five-digit number combination. Password 2 is also provided by the manufacturer. This password
enables the service personnel to access the Service menu which is not accessible for the user.
