n E5-07: Motor q-Axis Inductance (Lq)
Sets the q-Axis inductance in 0.01 mH units.
No. Parameter Name Setting Range Default
E5-07 Motor q-Axis Inductance 0.00 to 600.00 mH
Determined by
o2-04
n E5-09: Motor Induction Voltage Constant 1 (Ke)
Sets the induced peak voltage per phase in units of 0.1 mV/(rad/s) [electrical angle]. Set this parameter when using an IPM
motor with variable torque.
No. Parameter Name Setting Range Default
E5-09 Motor Induction Voltage Constant 1 0.0 to 2000.0 mV/(rad/s)
Determined by
o2-04
Note: Set E5-24 to 0 when setting E5-09. However, setting both E5-09 and E5-24 to 0 will trigger an alarm. An alarm will also be triggered if
neither E5-09 nor E5-24 are set to 0.
n E5-24: Motor Induction Voltage Constant 2 (Ke)
Set the induced phase-to-phase rms voltage in units of 0.1 mV/(r/min) [mechanical angle]. Set this parameter when using an
SPM Motor.
No. Parameter Name Setting Range Default
E5-24 Motor Induction Voltage Constant 2 0.0 to 6500.0 mV/(r/min)
Determined by
o2-04
Note: Set E5-24 to 0.0 when setting E5-09. However, setting both E5-09 and E5-24 to 0.0 will trigger an alarm. An alarm will also be triggered
if neither E5-09 nor E5-24 are set to 0.0.
n H3-03, H3-04: Terminal A1 Gain and Bias Settings
Parameter H3-03 sets the level of the selected input value that is equal to 10 Vdc (20 mA) input at terminal A1 (gain).
Parameter H3-04 sets the level of the selected input value that is equal to 0 V (4 mA, 0 mA) input at terminal A1 (bias).
Use both parameters to adjust the characteristics of the analog input signal to terminal A1.
No. Name Setting Range Default
H3-03 Terminal A1 Gain Setting -999.9 to 999.9% 100.0%
H3-04 Terminal A1 Bias Setting -999.9 to 999.9% 0.0%
Setting Examples
• Gain H3-03 = 200%, bias H3-04 = 0, terminal A1 as frequency reference input (H3-02 = 0):
A 10 Vdc input is equivalent to a 200% frequency reference and 5 Vdc is equivalent to a 100% frequency reference. Since
the drive output is limited by the maximum frequency parameter (E1-04), the frequency reference will be equal to E1-04
above 5 Vdc.
