Parameters 177
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.
Note:
If the drive is equipped with a brake chopper and
resistor, or a regenerative supply unit, the controller must be
disabled.
Disable
Overvoltage control disabled.
0
Enable
Overvoltage control enabled.
1
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
a stop. This will act as a power-loss ride-through functionality
in systems with high inertia, such as a centrifuge or a fan.
Disable
Undervoltage control disabled.
0
Enable
Undervoltage control enabled.
