SIEP C710606 10A YASKAWA AC Drive - V1000 PRELIM. Programming Manual
Note:
When parameter A1-02 = 0 (V/f Control) the factory default setting is 120. When parameter A1-
02 = 2 (Open Loop Vector) the factory default setting is 100.
■
b3-03: Speed Search Deceleration Time
Parameter b3-03 sets the output frequency reduction ramp used by Current Detection Speed
Search (b3-24 = 0) and by the Current Injection Method of Speed Estimation (b3-24 = 1).
The time entered into b3-03 will be the time to decelerate from maximum frequency (E1-04)
to minimum frequency (E1-09).
■
b3-05: Speed Search Delay Time
In cases where an output contactor is used between the drive and the motor, the contactor
must be closed before Speed Search can be performed. For Speed Search after a momentary
power loss parameter b3-05 can be used to delay the Speed Search start providing enough
time to operate the contactor.
When Speed Search at start is used, b3-05 will serve as the lower limit of the minimum
baseblock time (L2-03).
■
b3-06: Output Current 1 During Speed Search
Sets the current injected to the motor at the beginning of Estimation Type Speed Search as a
factor related to motor rated current set in E2-01 and E4-01. If the motor speed is relatively
slow when the drive starts to perform Speed Search after a long period of baseblock, it may
be helpful to increase the setting value. The output current during Speed Search is
automatically limited by the drive rated current. This function has no influence when
Current Detection Speed Search is used (b3-24 = 0)
