■
E5-11: Encoder Z-Pulse Offset
No.
(Hex.)
Name Description
Default
(Range)
E5-11
(0333)
Encoder Z-Pulse Offset
Sets the encoder Z-pulse offset.
0.0 degrees
(-180.0 - +180.0 degrees)
The drive uses the PM motor parameter settings and PM Stationary Auto-Tuning to set E5-11 to the value input for
“ Encoder Z-Pulse Offset ” automatically. The drive uses Z Pulse Offset Tuning or the Rotational Auto-Tuning to set
E5-11 .
■
E5-24: PM Back-EMF L-L Vrms (mV/rpm)
No.
(Hex.)
Name Description
Default
(Range)
E5-24
(0353)
PM Back-EMF L-L Vrms
(mV/rpm)
Sets the RMS value for PM motor line voltage.
0.1 mV/min -1
(0.0 - 6500.0 mV/min -1 )
Set this parameter when you use an SPM motor (SMRA-Series Pico motor).
PM motor Auto-Tuning automatically sets this parameter to the value of [Back-EMF Voltage Constant (Ke)].
When E5-01 = FFFF , only set E5-09 [PM Back-EMF Vpeak (mV/(rad/s))] or E5-24 as the induced voltage constant.
Note:
When you set this parameter, also set E5-09 = 0.0 . The drive will detect oPE08 [Parameter Selection Error] in these conditions:
•
E5-09 = 0.0 and E5-24 = 0.0
• E5-09 ≠ 0.0 and E5-24 ≠ 0.0
■
E5-25: Polarity Estimation Timeout
No.
(Hex.)
Name Description
Default
(Range)
E5-25
(035E)
Expert
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 set SynRM motors. Set these parameters to derate torque applications when a high level of
responsiveness and accurate speed control are not necessary. Auto-Tuning the drive will automatically set the E9
parameters .
If you cannot do EZ Tuning, you can also manually set the E9 parameters .
■
E9-01: Motor Type Selection
No.
(Hex.)
Name Description
Default
(Range)
E9-01
(11E4)
Motor Type Selection
Sets the type of motor.
0
(0 to 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)
