200 Parameters
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.
1
Enables/disables temperature-based output current limitation.
The limitation should only be disabled if required by the
application.
Disable
Thermal current limitation disabled.
0
Enable
Thermal current limitation enabled.
