• Refer to
Parameters that Change from the Default Settings with A1-02 [Control Method Selection] on page 146
initial value of b3-14 that applies when you set these parameters:
–A1-02 = 0, 8 [Control Method Selection = V/f, EZOLV]
–E9-01 = 0 [Motor Type Selection = Induction (IM)]
–b3-24 = 1 [Speed Search Method Selection = Speed Estimation Speed Search]
• The initial value of b3-14 is 0 when you set these parameters:
–A1-02 = 0, 8
–E9-01 = 0
–b3-24 = 2 [Current Detection 2]
• Refer to
Parameters that Change from the Default Settings with A1-02 [Control Method Selection] on page 146
initial value of b3-14 that applies when you set these parameters:
–A1-02 = 8 [EZOLV]
–E9-01 = 1, 2 [Permanent Magnet (PM), Synchronous Reluctance (SynRM)]
• When you change A1-02, b3-24, and E9-01, also set b3-14.

b3-17: Speed Est Retry Current Level
No.
Name
(Hex.)
b3-17 Speed Est Retry Current
Level
(01F0)
Expert
When a large quantity of current flows during Speed Estimation Speed Search, the drive temporarily stops operation
to prevent overvoltage and overcurrent. When the current is at the level set in b3-17, the drive tries speed search
again.

b3-18: Speed Est Retry Detection Time
No.
Name
(Hex.)
b3-18 Speed Est Retry Detection
Time
(01F1)
Expert
When the current is more than the level set in b3-17 [Speed Est Retry Current Level] during the time set in b3-18, the
drive tries speed search again.

(01F2)
If the drive does the number of Speed Search restarts set in this parameter, it will trigger an SEr [Speed Search Retries
Exceeded] error.

Sets the direction of Speed Search to the direction of the frequency reference or in the motor rotation
direction as detected by the drive.
V/f OLV/PM OLV/PM EZOLV
Sets the current level for the search retry function in Speed Estimation Speed Search as a percentage
where drive rated current is a setting value of 100%.
V/f OLV/PM EZOLV OLV/PM
Sets the length of time that the drive will wait to retry Speed Estimation Speed Search when too
much current flow stopped the Speed Search.
V/f OLV/PM EZOLV OLV/PM
Sets the number of times to restart Speed Search if Speed Search does not complete.
