Default Value: 100
Parameter 1803
Number:
Data Type: REAL
P 2.3.2.3 Overvoltage Control Ti
Set the scaling of the overvoltage control integral time.
Default Value: 100
Parameter
1804
Number:
Data Type: REAL
P 2.3.2.4 Overvoltage Control Td
Set the scaling of the overvoltage control derivation time.
Default Value:
100
Parameter 1805
Number:
Data Type: REAL
P 2.3.2.5 Overvoltage Control Upper limit
Set the upper limit for the overvoltage control. However, the voltage can be limited internally by the drive because of the available
hardware, temperature, and time.

Selection description
• The overvoltage controller does not affect motor speed in any manner.
• DC-link voltage is controlled with a brake chopper.
NOTE:
A DC-link overvoltage fault is usually triggered when the DC-link voltage exceeds acceptable
levels.
When the DC-link voltage level exceeds the overvoltage level, motor speed or deceleration is lim-
ited by the controller.
