Description: Sets the lower threshold for the DC link voltage.
For p1240 = 2, 3, 8, 9, this threshold is used as limit setpoint for the Vdc_min controller.
For p1240 = 5, 6, for DC link voltages below this threshold, an appropriate fault is output.
Dependency: Refer to: p1240, p1244, p1250
Note: For p1248 > 0.93 * "parameterized DC link voltage" input of values is rejected. For p0204.0 = 1, the following
applies:
"Parameterized DC link voltage" = p0210
For p0204.0 = 0, the following applies:
"Parameterized DC link voltage" = p0210 * 1.4142
Description: Sets the lower speed threshold for the Vdc_max controller. When this speed threshold is fallen below, the Vdc_max
control is switched-out and the speed is controlled using the ramp-function generator.
Note: For fast braking where the ramp-function generator tracking was active, it is possible to prevent the drive rotating in
the opposite direction by increasing the speed threshold and setting a final rounding-off time in the ramp-function
generator (p1131). This is supported using a dynamic setting of the speed controller.
Description: Sets the proportional gain for the Vdc controller (DC link voltage controller).
Dependency: Refer to: p1240, p1244, p1248
Description: Sets the proportional gain for the Vdc controller (DC link voltage controller).
Dependency: The effective proportional gain is obtained taking into account p1243 (Vdc_max controller dynamic factor).
