Polarity Estimation
Timeout
Sets the function that switches polarity for initial polarity estimation.
Usually it is not necessary to change this setting.
0
(0, 1)
When “Sd = 1” is shown on the motor nameplate or test report for Yaskawa motors, set this parameter to 1.
0 : Disabled
1 : Enabled
◆ E9: Motor Setting
E9 parameters are used to configure induction motors, PM motors, and SynRM motors. Configure these
parameters only for derating torque applications in which a high level of responsiveness and accurate speed
control are not required.
E9 parameters are automatically configured with values input by the Auto-Tuning process for motor parameter
settings. E9 parameters can be manually configured when the EZ Tuning process cannot be performed.
■ E9-01: Motor Type Selection
No.
(Hex.)
Name Description
Default
(Range)
E9-01
(11E4)
Motor Type Selection
Sets the type of motor.
0
(0 - 2)
EZ Tuning automatically sets this parameter to the value of [Motor Type Selection].
0 : Induction (IM)
1 : Permanent Magnet (PM)
2 : Synchronous Reluctance (SynRM)
■ E9-02: Maximum Speed
No.
(Hex.)
Name Description
Default
(Range)
E9-02
(11E5)
Maximum Speed
Sets the maximum speed of the motor.
Determined by E9-01
(40.0 - 120.0 Hz)
Note:
The unit of measure changes when the setting of o1-04 [V/f Pattern Display Unit].
EZ Tuning automatically sets this parameter to the value of [Motor Max Revolutions].
■ E9-03: Rated Speed
No.
(Hex.)
Name Description
Default
(Range)
E9-03
(11E6)
Rated Speed
Sets the rated rotation speed of the motor.
Determined by E9-01
(100 - 7200 min
-1
)
EZ Tuning automatically sets this parameter to the value of [Rated Speed].
Note:
Set E9-01 = 0 [Motor Type Selection = Induction (IM)] before you set this parameter.
■ E9-04: Base Frequency
No.
(Hex.)
Name Description
Default
(Range)
E9-04
(11E7)
Base Frequency
Sets the rated frequency of the motor.
Determined by E9-01
(40.0 - 120.0 Hz)
