List of parameters
p1240 = 2, 3:
When the lower DC link voltage threshold is reached (p1248), the following applies:
- the Vdc_min controller limits the energy taken from the DC link in order to keep the DC link voltage above the min-
imum DC link voltage when accelerating.
- the motor is braked in order to use its kinetic energy to buffer the DC link.
p1240 = 4, 5, 6:
When the threshold in p1244 or p1248 is reached, the DC link voltage monitoring initiates a fault with a response
and therefore reduces additional negative effects on the DC link voltage.
p1240 = 7, 9:
As for p1240 = 1, 3. However, the motor is prevented from accelerating due to the fact that other drives are regen-
erating. The effective lower torque limit cannot exceed the offset of the torque limit (p1532).
p1240 = 8, 9:
As for p1240 = 2, 3. However, the motor is prevented from braking due to the fact that the DC link voltage has been
lowered. The effective upper torque limit cannot be less than the offset of the torque limit (p1532).

165 [V]
Description: Sets the upper threshold for the DC link voltage.
For p1240 = 1, 3, 7, 9, this threshold is used as limit setpoint for the Vdc_max controller.
For p1240 = 4, 6, for DC link voltages above this threshold, an appropriate fault is output.
Dependency: Refer to: p1240, p1248, p1250
Note: For p1244 < 1.07 * "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 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
