Default Value: 100
Unit: %
P 2.3.2.4 Overvoltage Control Td
Description: Set the scaling of the overvoltage control derivation time.
Default Value: 100
Unit: %
P 2.3.2.5 Overvoltage Control Upper limit
Description: 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.
Default Value: 796.5

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.
