47 Voltage ctrl
Overvoltage and undervoltage control settings.
See also DC voltage control on page 76.
47.01 Overvolt ctrl Enables the overvoltage control of the intermediate DC link.
Fast braking of a high inertia load causes the voltage to rise
to the overvoltage control limit. To prevent the DC voltage
from exceeding the limit, the overvoltage controller
automatically decreases the braking torque.
Disable Overvoltage control disabled. 0
Enable Overvoltage control enabled. 1
47.02 Undervolt ctrl Enables the undervoltage control of the intermediate DC link.
If the DC voltage drops due to input power cut off, the
undervoltage controller will automatically decrease the motor
torque in order to keep the voltage above the lower limit. By
decreasing the motor torque, the inertia of the load will
cause regeneration back to the drive, keeping the DC link
charged and preventing an undervoltage trip until the motor
coasts to stop. This will act as a power-loss ride-through
functionality in systems with high inertia.
Disable Undervoltage control disabled. 0
Enable Undervoltage control enabled. 1
47.03 SupplyVoltAutoId Enables the auto-identification of the supply voltage.
Disable Auto-identification of supply voltage disabled. 0
Enable Auto-identification of supply voltage enabled. 1
47.04 Supply voltage Defines the nominal supply voltage. Used if auto-
identification of the supply voltage is not enabled by
parameter 47.03 SupplyVoltAutoId.
0 … 1000 V Nominal supply voltage. 10 = 1 V
