Description: Sets the maximum steady-state DC link voltage. When the DC link voltage setpoint reaches the threshold, alarm
A06800 is output.
The setpoint for the DC link voltage in p3510 is limited to the value in p0280.
The voltage can be increased (boosted) using the modulation depth reserve controller. The modulation depth
reserve (p3480) can be too low if p0210 (drive unit supply voltage) was incorrectly parameterized, a line overvolt-
age condition is present or a high reactive current is required.
Dependency: Refer to: p0210
Refer to: A06800
Warning: Before increasing the voltage limit for pulsed operation of a controlled booksize infeed with line supply voltages
p0210 > 415 V it should be checked whether the motors, connected to the DC link, are specified for the higher
motor voltages.
The warning information associated with p0210 must be carefully observed.
Caution: All motors connected to the DC link must be rated for the maximum DC-link voltage set in this parameter.
Notice: For chassis power modules, for the extended line supply voltage range from 500 V to 690 V, the value in p0280 is
automatically adapted if the line supply voltage in p0210 is changed. The individual parameter setting for p0280 is
then lost and if necessary must be re-entered.
Note: A brief, dynamic increase of the DC link voltage does not result in an alarm.
Pre-setting values:
380 ... 480 V booksize units: 660 V
380 ... 480 V chassis units: 750 V
500 ... 690 V chassis units: 0.875 * p0210 + 502 V
Maximum values:
380 ... 480 V booksize units: 785 V
380 ... 480 V chassis units: 785 V
500 ... 690 V chassis units: 1130 V
Description: Sets the alarm threshold for a line supply overvoltage condition.
The setting is made as a percentage of the drive unit supply voltage (p0210).
Dependency: Refer to: p0211, p0221, p0222, p0223, p0224, p0225, p0226
Note: If synchronizing voltages are not detected, the line supply voltage is estimated using a model. It is therefore impor-
tant to ensure that drive unit data is correctly specified.
