5.1.11.2 Example for determining the saturation characteristic
Given values:
r Rated motor current: 5 A
r Maximum motor current: 20 A
r Maximum process current: 15 A (must be set later in C00022
)
Procedure:
1. Deactivate correction (C02859 = "off").
2. Set the maximum current up to which the motor is to be operated in the process in
C02855
(in this example "15 A").
The value set in C02855
must be higher or the same as C00022.
3. Adjust the current controller with different current setpoints and note the
corresponding settings for Vp and Tn.
The procedure for the adjustment is described in the chapter "Optimise current
controller".
The current setpoints that are to be set for the prevailing adjustment in C00022
result from the scaling of the maximum process current to the X axis of the
saturation characteristic.
Which points are required to display the saturation characteristic with a sufficient
quality, varies from motor to motor and must therefore be detected individually.
For this example currents have been selected which are situated on the grid points
5, 9, 13 and 15 a measurement has been carried out at rated motor current:
