YASKAWA V1000 - Troubleshooting

n
b3-10: Speed Search Detection Compensation Gain
This parameter sets the gain for the detected motor speed of the Speed Estimation Speed Search. The drive will start the
motor
at the estimated speed multiplied by b3-10.
The setting should be increased if an overvoltage fault occurs when the
drive restarts the motor. This function has no influence when Current Detection Speed Search is used (b3-24 = 0).
No. Name Setting Range Default
b3-10 Speed Search Detection Compensation Gain 1.00 to 1.20 1.10
Note: Increase this value if overvoltage occurs when performing Speed Search at start after a relatively long period of baseblock.
n
b3-14: Bi-Directional Speed Search Selection
Sets
how the drive determines the motor rotation direction when performing Speed Estimation Speed Search. The setting
has no influence on Current Detection Speed Search (b3-24 = 0).
No. Parameter Name Setting Range Default
b3-14 Bi-Directional Speed Search Selection 0 or 1 0
Setting 0: Disabled
The drive uses the frequency reference to determine the direction of motor rotation in order to restart the motor.
Setting 1: Enabled
The drive detects the motor rotation direction in order to restart the motor.
n
b3-17: Speed Search Restart Current Level
If there is a fairly large difference between the estimated frequency and the actual motor speed when performing Speed
Estimation, a large current can flow. This parameter sets the current level at which Speed Estimation is restarted, thus
avoiding
overcurrent and overvoltage problems. The parameter is
set as a percentage of the drive rated current. This function
has no influence when Current Detection Speed Search is used (b3-24 = 0).
No. Name Setting Range Default
b3-17 Speed Search Restart Current Level 0 to 200% 150%
n
b3-18: Speed Search Restart Detection Time
Sets
the time the current must be above
the level set in b3-17 before Speed Search is restarted. This function has no influence
when Current Detection Speed Search is used (b3-24 = 0)
No. Name Setting Range Default
b3-18 Speed Search Restart Detection Time 0.00 to 1.00 s 0.10 s
n
b3-19: Number of Speed Search Restarts
Sets the number of times the drive should attempt to find the speed and restart the motor using Speed Estimation Speed
Search. This function has no influence when Current Detection Speed Search is used (b3-24 = 0).
No. Name Setting Range Default
b3-19 Number of Speed Search Restarts 0 to 10 3
n
b3-24: Speed Search Method Selection
Sets the Speed Search method used.
Note: For
explanations of the Speed Search methods, Refer to
Current Detection Type Speed Search (b3-24 = 0) on page 126 and Refer to
Speed Estimation Type Speed Search (b3-24 = 1) on page 125.
No. Parameter Name Setting Range Default
b3-24 Speed Search Method Selection 0 or 1 0
Setting 0: Current Detection Speed Search
Setting 1: Speed Estimation Speed Search
n
b3-25: Speed Search Wait Time
Sets the wait time between Speed Search restarts.
No. Name Setting Range Default
b3-25 Speed Search Wait Time 0.0 to 30.0 s 0.5 s
