30.18 Torq lim sel
See diagram at
Maximum torque limit 2.
Defines the maximum allowed power fed by the
inverter to the motor in percent of nominal motor
power.
Maximum motoring power.
Defines the maximum allowed power fed by the
motor to the inverter in percent of nominal motor
power.
Maximum generating power.
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.
Overvoltage control disabled.
Overvoltage control enabled.
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.
Undervoltage control disabled.
Undervoltage control enabled.
