08- 01 Trip Prevention Level During Acceleration
Range 【50 ~ 200】%
Trip prevention adjustment level during acceleration to prevent over current (OC-A) trips.
If trip prevention during acceleration is enabled and an over current occurs due to the load, then
the acceleration is interrupted until the over current level is dropped below the setting in 08-01
then the acceleration is resumed.
08- 02 Trip Prevention Level During Deceleration
Range 【50 ~ 200】%
Trip prevention adjustment level during deceleration to prevent over Voltage (OV-C) trips.
If trip prevention during deceleration is enabled and an over voltage occurs during stopping due
to the load, then the deceleration is interrupted until the over voltage level is dropped below the
setting in 08-02 then the deceleration is resumed.
08- 03 Trip Prevention Level during continuous Run Mode
Range 【50 ~ 200】%
Trip prevention adjustment level during continuous Run to prevent over current (OC-C) trips.
If trip prevention during continuous Run is enabled and an over current occurs due the load
such as a sudden transient load, then the output frequency is reduced by decelerating to a
lower speed until the over current level is dropped below the preset in 08-03, then the output
frequency accelerates back to the normal running frequency.
08- 04 Over voltage Prevention Level during Run Mode
Range
200:【350~390】VDC
400:【700~780】VDC
Over voltage prevention level can be set by parameter 08-04 when necessary.
When the DC bus voltage is higher than 08-04, inverter will keep running, the output
frequency will be decreased once the DC bus voltage reduced. It’s the over voltage
prevention function, inverter will not appear any error message.
(If the DC bus voltage higher than OV protection level, inverter will appear “OV”
message)
