6.21.2 Setting motor constants for PM motors
f400
: Auto-tuning
f459
: Load inertia moment ratio
f402
: Automatic torque boost value
f912
: q-axis inductance
f405
: Motor rated capacity
f913
: d-axis inductance
f415
: Motor rated current
f915
: PM control mode selection
f417
: Motor rated speed
To use vector control for PM motor is required. Setting V/F control mode selection (
pt
) should be set as
6
.
Caution:
If the settings for V/F control mode selections
pt
is
6
: vector control for PM motor
Look at the motor's name plate and set the following parameters.
vl
: Base frequency 1 (rated frequency) that is calculated from Back EMF
vlv
: Base frequency voltage 1 (rated voltage) that is calculated from Back EMF
f405
: Motor rated capacity
f415
: Motor rated current
f417
: Motor rated speed
f912
: Q axis inductance per phase
f913
: D axis inductance per phase
[Selection 1: Setting PM motor control and auto-tuning ]
After setting
pt
=
6
, auto-tuning occurs.
Set the auto-tuning parameter
f400
to
2
(Auto-tuning enabled)
