9.11.1.2.2 Entering the plant data
rated motor current
rated motor voltage
rated motor speed
rated frequency of the motor voltage
power factor of the motor. The value given on the type plate of the motor
must be multiplied by 100.
9.11.1.2.3 Automatic measurement of motor parameters
The unit carries out a measurement of the motor characteristic and adjusts the corresponding
parameters for the motor control automatically. In this operating mode you can measure the motor
parameters once or during each travel operation.
To ensure an error-free measurement, the system data must be entered correctly !
Go to menu
Setting - Open Loop4.
Use the E-key to open the menu.
Select parameter
R1MessEn.
Enter "1" to activate the measurement.
Issue travel command. After switching on the output stage the unit will
determine the stator resistance and the required starting voltage of the
motor within a few milliseconds.
Then, the travel operation is carried out and the parameter
R1MessEn
is
set to 0.
Note :
Normally, it is sufficient to measure the motor parameters once during commissioning. However, if the
travel behaviour worsens significantly if the motor gets hotter, this is due to the fact that the motor
parameters depend on the temperature.
In this case you can activate a permanent measurement by entering "2".
Now, the unit will carry out a measurement upon each start. In this way,
motor parameter changes which are due to an increased motor
temperature are considered.
Carry out travel operation in both directions.
Note:
If the torque is insufficient (e.g. motor stops during slow down), the parameter
U_Start must be
increased.
