7.2.1 Configuration
The software of the frequency inverter offers several configuration options. These
differ with respect to the way in which the drive is controlled. Parameter
Configuration 30 determines the assignment and basic function of the control inputs
and outputs as well as the software functions. Analog and digital inputs can be
combined and complemented by optional communication protocols as further
reference value sources. In these brief instructions, the sensor-less control and the
sensor-less field oriented control are described in Configuration 110 and Configuration
410, respectively.
Configuration 110, sensorless control
Configuration 110 contains the functions for variable-speed control of a 3-phase
machine in a wide range of standard applications. The motor speed is set according to
the V/f characteristic in accordance with the voltage/frequency ratio.
Configuration 410, sensorless field-oriented control
Configuration 410 contains functions for sensorless, field-oriented control of a 3-phase
machine. The current motor speed is determined from the present currents and
voltages in combination with the machine parameters. In this configuration, parallel
connection of several 3-phase motors is possible to a limited extent only.
7.2.2 Data Set
Data set change-over enables the selection of one of four data sets for storing
parameter settings. The default setting dS0 is recommended. If data set 0 is selected
(factory setting), the parameter values saved in data set 0 are copied to data sets 1 to
4. In this way, all values determined during the guided commissioning are saved in all
data sets. The frequency inverter uses data set 1 as the active data set. For more
information, refer to the operating instructions.
Data Set Setup
Parameter dS Function
0 All data sets (DS0)
1 Data set 1 (DS1)
2 Data set 2 (DS2)
3 Data set 3 (DS3)
4 Data set 4 (DS4)
7.2.3 Motor Type
The properties of the control functions and methods to be set vary depending on the
motor which is connected. The parameter
Motor type 369 offers a range of motor
variants with the corresponding table values. The verification of the entered rated
values and the guided commissioning are carried out on the basis of the
parameterized motor type. The selection of motor types varies depending on the
requirements of the different control methods. In instructions the functionality and
operating performance are described for 3-phase motors.
Caution! Polling and presetting of parameter values depends on the operation mode
selected for parameter
Motor type 369.
If the motor type is not entered correctly, the drive may be damaged.
