Auto Restart Setting Details
Pr.08 RST Restart,
Pr.09 Retry Number,
Pr.10 Retry Delay
Only operates when Pr.08 (RST Restart) is set to 1(Yes). The number of attempts
to try the auto restart is set at Pr.09 (Auto Restart Count).
If a fault trip occurs during operation, the inverter automatically restarts after
the set time programmed at Pr.10 (Retry Delay). At each restart, the inverter
counts the number of tries and subtracts it from the number set at Pr.09 until
the retry number count reaches 0.
After an auto restart, if a fault trip does not occur within 60 sec, it will increase
the restart count number. The maximum count number is limited by the
number set at Pr.09 (Auto Restart Count).
If the inverter stops due to low voltage, emergency stop (Bx), inverter
overheating, or hardware diagnosis, an auto restart is not activated. At auto
restart, the acceleration options are identical to those of speed search
operation. Codes Cn.72–
75 can be set based on the load. Information about the
speed search function can be found at 5.15 Speed Search Operation on page 170.
[Example of auto restart with a setting of 2]
If the auto restart number is set, be careful when the inverter resets from a fault trip. The motor may
automatically start to rotate.
