E5-09: PM Back-EMF Vpeak (mV/(rad/s))
No.
Name
(Hex.)
E5-09 PM Back-EMF
Vpeak (mV/(rad/s))
(0331)
Set this parameter when using an IPM motor with derated torque (SSR1 series) or an IPM motor with constant
torque (SST4 series).
Parameter E5-09 is automatically set to the value input for [PM Motor Induced Voltage Const] in units of mV/
(rad/s) by the Auto-Tuning process for PM motor parameter settings.
If E5-01 = FFFF is set, only set either E5-09 or E5-24 [PM Back-EMF L-L Vrms (mV/rpm)] as the induced
voltage constant.
Note:
Set E5-24 = 0.0 when setting E5-09. If both E5-09 = 0.0 and E5-24 = 0.0 are set or neither of these parameters is set to 0.0, oPE08
[Parameter Selection Error] is detected.
■
E5-11: Encoder Z-Pulse Offset
No.
Name
(Hex.)
E5-11 Encoder Z-Pulse
Offset
(0333)
The value of E5-11 is automatically set to the value input for "Encoder Z-Pulse Offset" by the PM motor
parameter settings and the PM Stationary Auto-Tuning process. Parameter E5-11 is configured with the result of
the Z Pulse Offset Tuning or the Rotational Auto-Tuning process.
■
E5-24: PM Back-EMF L-L Vrms (mV/rpm)
No.
Name
(Hex.)
E5-24 PM Back-EMF L-L
Vrms (mV/rpm)
(0353)
Set this parameter when using an SPM motor (SMRA Series Pico motor).
Parameter E5-24 is automatically set to the value input for "PM Motor Induced Voltage Const" in units of mV/
-1
min by the Auto-Tuning process for PM motor parameter settings.
• Parameter E5-24 is automatically set by performing the PM Stationary Auto-Tuning process.
• Parameter E5-24 is configured with the result of the PM Rotational Auto-Tuning process.
If E5-01 = FFFF is set, only set either E5-09 [PM Back-EMF Vpeak (mV/(rad/s))] or E5-24 as the induced
voltage constant.
Note:
Set E5-09 = 0.0 when setting E5-24. If both E5-09 = 0.0 and E5-24 = 0.0 are set, oPE08 [Parameter Selection Error] is detected. If
neither E5-09 or E5-24 is set to 0.0, oPE08 is detected.
■
E5-25: Polarity Estimation Reversal
No.
Name
(Hex.)
E5-25 Polarity Estimation
Reversal
(035E)
Set this parameter to 1 when "Sd = 1" is included in the motor nameplate or test report for Yaskawa motors.
0 : Disabled
1 : Enabled
