5.5 E: Motor Parameters

172 YASKAWA ELECTRIC SIEP C710616 30B YASKAWA AC Drive T1000A Technical Manual

n 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

SSR1 series IPM motor with derated torque or an SST4 series IPM motor with constant torque.

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 E5-24 = 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.

n E5-11 Encoder Z-Pulse Offset (Δθ)

Sets the offset between the rotor magnetic axis and the Z-pulse of the encoder connected. This parameter is set during

Parameter Auto-Tuning for PM motors and during Z Pulse Tuning.

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 SMRA Series SPM Motor.

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.
