(Ex.6) When frequency acquisition restarting is selected ([bb-41]=02)
• After the “Retry stand-by time for instantaneous power failure and insufficient voltage [bb-26]” has
elapsed, the output starts at a frequency conforming to the “Constant (frequency) for frequency
acquisition restarting [bb-44].” After that, during a time of the “Constant (voltage) for restarting
[bb-45],” the motor speed is acquired. At that time, to reduce the output current with the “Restarting
level of acquisition [bb-43],” deceleration occurs in accordance with the “Constant (frequency) for
restarting [bb-44].”
• When the output current lowers below the “Restarting level of acquisition [bb-43],” acceleration starts.
If a trip occurs due to an excessive current even in this method, lower the “Restarting level of acquisi-
tion [bb-43]” or the “Excessive current prevention level [bb-46].”
Precautions for Correct Use
When the “Start frequency selection [bb-47]” is set to “00 (Frequency at the time of interrup-
tion),” the operation starts at a frequency at the time of the previous interruption even when a
reset signal is input during retry stand-by.
