It is used to set the level. When the DC BUS voltage is lower than Pr06-00 Low voltage level, drive
will stop output and free to stop.

Over-voltage Stall Prevention
Factory Setting: 380.0/760.0
Settings 230V Series: 0.0~450.0V

0: Disabled
When Pr.06-01 is set to 0.0, the over-voltage stall prevention function is disabled. When braking
units or resistors are connected to the drive, this setting is suggested.
During deceleration, the DC bus voltage may exceed its Maximum Allowable Value due to motor
regeneration. When this function is enabled, the AC motor drive will not decelerate further and
keep the output frequency constant until the voltage drops below the preset value again.
This function is used for the occasion that the load inertia is unsure. When it stops in the usual load,
the over-voltage won’t occur during deceleration and fulfill the setting of deceleration time.
Sometimes, it may not stop due to over-voltage during decelerating to stop when increasing the
load regenerative inertia. At this moment, the AC drive will auto add the deceleration time until drive
stop.
When the over-voltage stall prevention is enabled, drive deceleration time will be larger than the
setting.
When there is any problem as using deceleration time, refer to the following items to solve it.
1. Add the suitable deceleration time.
2. Add brake resistor (refer to appendix B-1 for details) to consume the electrical energy that
