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]
Correct the parameter settings.
Note:
You cannot use Speed Feedback (V/F
Control) with the Motor Switch
function.
When
A1-02 = 5 [OLV/PM]
,
you set
E5-02 to E5-07 [PM
Motor Parameters] = 0
.
•
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.
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
]
Set
E5-09
or
E5-24
to the correct value.
When
A1-02 = 5, 6
, you set
E5-
09 ≠ 0
and
E5-24 ≠ 0
.
Set
E5-09 = 0
or
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
.
Correct the parameter settings.
When
A1-02 = 6
, you set these
parameters:
•
n8-35 = 0 [Initial Pole
Detection Method = Pull-in]
•
n8-57 = 1 [Enabled]
Correct the parameter settings.
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]
When
E9-01 = 1 or 2
,
set b3-24 = 1
[Speed Estimation]
.
