■
b3-18: Speed Search Restart Detection Time
Sets the time for which the current must be above the level set in b3-17 before restarting Speed Search.
■
b3-19: Number of Speed Search Restarts
Sets the number of times the drive should attempt to find the speed and restart the motor. If the number of restart attempts
exceeds the value set to b3-19, the SEr fault will occur and the drive will stop.
■
b3-25: Speed Search Wait Time
Sets the wait time between Speed Search restarts. Increase the wait time if problems occur with overcurrent, overvoltage,
or if the SEr fault occurs.
■
b3-30: Torque Compensation Time Constant during Speed Search
Sets the primary delay time of the torque compensation function during Speed Search, in ms units.
■
b3-31: Current Suppression Start Level during Voltage Recovery
Sets the level at which to start the operation to extend the voltage recovery time to suppress the current when the voltage
is recovered during Speed Search. The setting assumes the motor no-load current to be 1.0.
■
b3-32: Current Suppression Time Constant during Voltage Recovery
Sets the time constant for filtering of the level for extending the voltage recovery time to suppress the current when the
voltage is recovered during Speed Search.
■
b3-33: Recovery Waiting Time after Speed Search Completion
Sets the waiting time between the end of Speed Search and the switch to normal control. The frequency reference is
maintained during this time.
■
b3-34: Software CLA Current Limit Value 1 during Speed Search
Sets the software current limit value during Speed Search as a percentage of the motor rated current.
