Revision Jan. 2009, 06EE, SW--PW V1.12/CTL V2.12 4-129
 Setting 2: the drive will operate by the min. frequency. It will accelerate to the master
frequency after the drive output frequency and motor rotor speed are synchronous. It is
recommended to use this setting for those motor loads which have a small inertia and large
resistance.
 When using with PG card, the speed search will start with the actual motor speed detected by
the drive and accelerate to the setting frequency (setting 1 and 2 are invalid at this moment).
 Related parameters: Pr.08.05(Maximum Allowable Power Loss Time), Pr.08.07(Baseblock
Time for Speed Search (BB)) and Pr.08.08(Current Limit for Speed Search)
08.05 Maximum Allowable Power Loss Time Unit: 0.1
Settings 0.1 to 20.0 sec Factory Setting: 2.0
 If the duration of a power loss is less than this parameter setting, the AC motor drive will act by
Pr.08.04 setting. If it exceeds the Maximum Allowable Power Loss Time, the AC motor drive
output is then turned off (coast stop).
 The selected operation after power loss in Pr.08.04 is only executed when the maximum
allowable power loss time is ≤20 seconds and the AC motor drive displays “Lu”.
But if the AC motor drive is powered off due to overload, even if the maximum allowable power
loss time is ≤20 seconds, the operation mode as set in Pr.08.04 is not executed. In that case it
starts up normally.
08.06 Base Block Speed Search
Factory Setting: 1
Settings 0 Disable
1 Speed search starts with last frequency
2 Speed search starts with minimum output frequency (Pr.01.05)
 This parameter determines the AC motor drive restart method after External Base Block is
enabled(one of Pr.04.05~04.08 is set to 9).
 The speed search actions between Pr.08.04 and Pr.08.06 are the same.
 The priority of Pr.08.06 is higher than Pr.08.04. That is, Pr.08.04 will be invalid after Pr.08.06 is
set and the speed search will act by Pr.08.06.
 Related parameters: Pr.08.07(Baseblock Time for Speed Search (BB)), Pr.04.05(Multi-function
Input Terminal (MI3)), Pr.04.06(Multi-function Input Terminal (MI4)), Pr.04.07(Multi-function
Input Terminal (MI5)) and Pr.04.08(Multi-function Input Terminal (MI6))
