06 Protection Parameters
Low Voltage Level
Settings 230V Series:
This parameter is used to set the Low Voltage level. When the DC BUS voltage is lower than
Pr06-00, drive will stop output and free to stop.
If the drive is triggered LV fault during the operation, drive will stop output and free to stop. There
are three LV faults, LvA (LV during acceleration), LvD (LV during deceleration), and LvN (LV in
constant speed) which will be triggered in different stage of drive operation. These faults need to be
reset manually to restart the drive, while setting restart after momentary power off function (Pr07-06,
Pr07-07), the drive will restart automatically.
If LV is triggered when the drive is in stop status, the fault is named LvS (LV during stop), which will
not be recorded, and the drive will restart automatically when input voltage is 30Vdc (230V series)
or 60Vdc (460V series) higher than LV level.
Over-voltage Stall Prevention
Settings
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.
When the setting is not 0.0, the over-voltage stall prevention is activated. This setting should refer
to power supply system and loading. If the setting is too low, then over-voltage stall prevention will
be easily activate, which may increase deceleration time.
