Active frequency matching restart at over current/overvoltage ([b008] = 04)
ï‚Ÿ To perform the active frequency matching restart when an overcurrent/overvoltage occurs, set
the "Restart mode selection after overvoltage/overcurrent error [b008]" to "Active frequency
matching restart (04)".
ï‚Ÿ If restart is selected for when there was an overcurrent/overvoltage, the restart is performed only
for the number of times set in "Number of retries after overvoltage/overcurrent [b010]", and the
inverter trips the next time.
Restart mode selection
after overvoltage/
overcurrent error
Performs the active frequency
matching restart.
Number of retries after
overvoltage/overcurrent
Sets the number of retries for
when there is an overvoltage/
overcurrent.
Retry wait time after
overvoltage/overcurrent
error
Sets the wait time from when the
error occurrence until the restart.
Active frequency matching
restart level
Sets the current limit value at the
active frequency matching restart.
(0.2 to 2.0) × rated current (A)
(ND mode)
(0.2 to 1.5) × rated current (A)
(LD mode)
Active frequency matching
restart constant (speed)
Sets the deceleration time when
the current is increased.
Active frequency matching
restart speed selection
Starts at the frequency of the
previous power interruption.
Starts at the maximum frequency
setting.
Starts at the current command
frequency.
ï‚Ÿ Even when the retry operation is selected for a trip, if the trip factor has not been released after
the retry wait time, the trip is detected again. In this case, increase the retry wait time.
