Over-Voltage Limit Operation
Program
Protection
Stall
This parameter Enables/Disables the
Over-Voltage Stall
function. When
enabled, this function causes the drive to extend the deceleration time when the
DC bus voltage increases due to transient voltage spikes, regeneration, supply
voltage out of specification, etc., in an attempt to reduce the bus voltage.
An
Over-Voltage Stall
increases the output frequency of the ASD during
deceleration for a specified time in an attempt to prevent an
Over-Voltage
Trip
.
If the over-voltage threshold level setting of
is exceeded for over 4 mS, an
Over-Voltage Trip
will be incurred.
Parameter
(Power Running Stall Continuous Trip Detection Time) setting
may affect the performance of this setting.
Note:
This setting may increase deceleration times.

This parameter sets the maximum value of the output voltage of the drive. The
Motor 1 Maximum Output Voltage
is the

cannot be higher than the input voltage.
The actual output voltage will be influenced by the input voltage of the ASD
