SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
When you enable the Run command and input the
Speed Search from Fmax or Fref [H1-xx = 61, 62]
from a multi-
function input terminal, the drive will do Speed Search and start to operate the motor.
1 : Enabled
Enter the Run command to do Speed Search. The drive completes Speed Search then starts to operate the motor.

SpeedSearch Deactivation
Current
Sets the current level that stops Speed Search as a percentage of the drive rated output current.
Usually it is not necessary to change this setting.
120%
(0 - 200%)
If the drive cannot restart the motor, decrease this setting.

Speed Search Deceleration
Time
Sets the deceleration time during Speed Search operation. Set the length of time to decelerate from
the maximum output frequency to the minimum output frequency.
2.0 s
(0.1 - 10.0 s)
This is the output frequency deceleration time used by Current Detection Speed Search and by the Current Injection
Method of Speed Estimation Speed Search.
Note:
If the drive detects
oL1 [Motor Overload]
during Current Detection Speed Search, decrease the value set in
b3-03
.

(0194)
V/f Gain during Speed
Search
Sets the ratio used to reduce the V/f during searches to reduce the output current during speed
searches.
Determined by o2-04
(10 - 100)
Use the this formula to calculate the output voltage during Speed Search:
Output voltage during Speed Search = Configured V/f × b3-04
When the current detection search operates correctly, this configuration is not necessary.

(0195)
Speed Search Delay Time
Sets the Speed Search delay time to activate a magnetic contactor installed between the drive and
motor.
0.2 s
(0.0 - 100.0 s)
When you use a magnetic contactor between the drive and motor, you must close the contactor before the drive will
do Speed Search. This parameter sets a delay time to activate the magnetic contactor.

Speed Estimation Current
Level 1
Sets the level of current that flows to the motor during Speed Estimation Speed Search as a
coefficient of the motor rated current. Usually it is not necessary to change this setting.
Determined by o2-04
(0.0 - 2.0)
When the speed estimation value is the minimum output frequency, increase this setting. You can do this when the
motor coasts at a high speed while the drive estimates the speed during Speed Estimation Speed Search. The limit of
the output current during speed search is automatically the drive rated current.
Note:
When the drive cannot accurately estimate the speed after you adjust this parameter, use Current Detection Speed Search.
