Causes
When A1-02 = 0 [V/f], you used
these parameter settings:
• H6-01 = 3 [Terminal RP
Pulse Train Function =
Speed Feedback (V/F
Control)]
• H1-xx = 16 [MFDI Function
Select = Motor 2 Selection]
When A1-02 = 5 [OLV/PM],
you set E5-02 to E5-07 [PM
Motor Parameters] = 0.
When A1-02 = 5, 6 [OLV/PM,
AOLV/PM], you used these
parameter settings:
• E5-09 = 0.0 [PM Back-EMF
Vpeak (mV/(rad/s)) = 0.0
mV/(rad/s)]
• E5-24 = 0.0 [PM Back-EMF
L-L Vrms (mV/rpm) = 0.0
mV/min -1 ]
When A1-02 = 5, 6, you set E5-
09 ≠ 0 and E5-24 ≠ 0.
When A1-02 = 6, you set these
parameters:
• n8-57 = 0 [HFI Overlap
Selection = Disabled]
• You set E1-09 [Minimum
Output Frequency] < the 5%
value of E1-06.
When A1-02 = 6, you set these
parameters:
• n8-35 = 0 [Initial Pole
Detection Method = Pull-in]
• n8-57 = 1 [Enabled]
When A1-02 = 8 [EZOLV], you
used these parameter settings:
• E9-01 = 1, 2 [Motor Type
Selection = Permanent
Magnet (PM), Synchronous
Reluctance (SynRM)]
• b3-24 = 2 [Speed Search
Method Selection = Current
Detection 2]

Possible Solutions
Correct the parameter settings.
Note:
You cannot use Speed Feedback (V/F
Control) with the Motor Switch
function.
• Set E5-01 [PM Motor Code
Selection] correctly as specified by
the motor.
• For specialized motors, refer to the
motor test report and set E5-xx
correctly.
Set E5-09 or E5-24 to the correct value.
Set E5-09 = 0 or E5-24 = 0.
Correct the parameter settings.
Correct the parameter settings.
When E9-01 = 1 or 2, set b3-24 = 1
