Motor Specific Parameters
For MagForce applications, the drive automatically sets:
•
PM Rs [Motor-09]:
Motor stator resistance.
•
PM Ld [Motor-10]:
Motor inductance d-axis.
•
PM Lq [Motor-11]:
Motor inductance q-axis.
•
PM Ke Coeff [Motor-13]:
Motor parameter Ke (Vphase, rms / krpm).
Autotune Characteristic Parameters
For MagForce applications, autotune is not needed. However, if the drive consistently exceeds the motor
current specification during DC Alignment and I/F control, then an autotune may be needed. Refer to
“Autotune Characteristic Parameters” on page 82
.
Tune motor control – DC Alignment
For MagForce applications, no adjustments are needed. However, if there are problems during DC Align

Tune motor control - I/F Control
For MagForce applications, no adjustments are needed. However, if there are problems during I/F Control,
refer to
“Tune motor control - I/F Control” on page 82
Tune motor control - PM Control
For MagForce applications, no adjustments are needed. However, if there are problems during PM Control,
refer to
“Tune motor control - PM Control” on page 83

Setup Non-Franklin Electric PM Motors
The X-Drive can be programmed to operate general purpose permanent magnet motors through the follow

ing procedure:
Basic Setup
IMPORTANT:
If the VFD has been used in a previous application, the drive parameters should be completely
reset using
Parameter Reset [ADV–03]
, option
4_Reset all Param
.
1.
Application [SET–00]:
Set to option 8_PM Motor. This selection assumes the use of a 4-pole, 3-phase
PM motor running at 120 Hz and automatically updatesrelevant parameters to the proper defaults.
IMPORTANT:
Do
NOT
use the MagForce selection with non-Franklin Electric permanent magnet
motors.
2.
Input Phase [SET–01]:
Verify that the setting matches the type of power supply— 3-phase (default).
3.
Motor Horsepower [SET–02]:
Enter the maximum rated horsepower from the motor nameplate.
4.
Motor FLA (SFA) [SET–03]:
Enter the rated motor FLA, found on the motor nameplate.
5.
Motor RPM [SET–04]:
Enter the rated motor RPM from the motor nameplate.
6.
Motor Voltage [SET–05]:
Enter the rated voltage from the motor nameplate.
7.
VFD Max Freq [VFD–00]:
The highest frequency (speed) allowable.
8.
VFD Base Freq [VFD–02]:
This should be set to the motor nameplate frequency rating.
9.
Carrier Freq [SET–06]:
This should be set to 4 kHz for sine filters and 2 kHz for dV/dt filters. Carrier
frequency should be at least 1.5 times the resonant frequency of the filter.
