5.5 E: Motor Parameters
178 YASKAWA ELECTRIC SIEP C710616 35D YASKAWA AC Drive E1000 Technical Manual
■ E5-05: Motor Stator Resistance (r1)
Set the resistance for one motor phase. When measuring the resistance manually, make sure not to enter the line-to-line
resistance into E5-05.
■
E5-06: Motor d-Axis Inductance (Ld)
Sets the d-axis inductance in 0.01 mH units. This parameter is set during the Auto-Tuning process.
■
E5-07: Motor q-Axis Inductance (Lq)
Sets the q-axis inductance in 0.01 mH units. This parameter is set during the Auto-Tuning process.
■
E5-09: Motor Induction Voltage Constant 1 (Ke)
Set 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 derated torque (SSR1 series or equivalent) or an IPM motor with constant torque (SST4 series or
equivalent).
Set the voltage constant with E5-09 or E5-24 when E5-01 is set to FFFF. This parameter is set during Auto-Tuning for
Yaskawa SSR1 or SST4 series PM motors.
Note: Ensure that E5-24 = 0 when setting parameter E5-09. An alarm will be triggered, however, if both E5-09 and E5-24 are set 0, or
if neither parameter is set to 0. When E5-01 = FFFF, then E5-09 = 0.0.
■ 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 (SMRA Series or equivalent).
When E5-01 is set to FFFF, use either E5-09 or E5-24 for setting the voltage constant. This parameter is set during
Parameter Auto-Tuning for PM motors.
Note: Ensure that E5-09 = 0 when setting parameter E5-24. An alarm will be triggered, however, if both E5-09 and E5-24 are set 0, or
if neither parameter is set to 0. When E5-01 = FFFF, then E5-09 = 0.0.
■ E5-25: Polarity Judge Selection
Sets the polarity level (SD) that determines the motor poles at start.
Setting 0: Positive Polarity
Setting 1: Negative Polarity
