Permanent Magnet Motor (Pm) - Delta C2000 series User Manual

Set Pr.05-00=6 to begin rolling test for IM motor flux curve. This function is available
when the drive is in FOC/TQC Sensorless control. User may begin auto-tuning after
setting up the motor information.
Set up Pr.01-01, 01-02, 05-01~05-04 according to the motor nameplate information。
Set Pr.05-00=6 and press【Run】, make sure no loading is applied to the motor
before setting Pr.05-00 to 6 and before performing auto-tuning.
When Pr.05-00=12, the drive begins FOC Sensorless inertia estimation for IM motor. This
function is available when the drive is in FOC/TQC Sensorless control. User may begin
auto-tuning after setting up the motor information.
Note: Make sure the motor parameters (no-load current, Rs, Rr, Lm and Lx) of the
drive are set before performing Pr.05-00=12 (auto-tuningfor FOC Sensorless interia
estimation for IM motor).
1. Set Pr.00-10=2 (torque mode)
2. Set Pr. 00-13=2 (TQCPG, Open-loop torque mode)
3. Set Pr. 05-00=12 and press【Run】to begin FOC Sensorless inertia measure
4. When the process of inertia estimation is completed, check Pr.11-01 (unit: PU Q8) and
see if the measured value is acceptable.
Set up Sensorless FOC Mode
1. Set Pr.00-10 = 0 (speed mode)
2. Set Pr.00-11 = 5 (FOC sensorless mode)
3. Set bit0 of Pr.11-00 to 1 (use ASR gain function to automatically adjust the ASR
bandwidth in Pr.11-03,11-04,11-05)
NOTE
In torque/vector control mode, it is not recommended to have motors run in parallel.
It is not recommended to use torque/vector control mode if motor rated power exceeds
the rated power of the AC motor drive.
When auto-tuning 2 motors, it needs to set multi-function input terminals (setting 14) or
change Pr.05-22 for motor 1/motor 2 selection.
The no-load current is usually 20~50% X rated current.
The rated speed can not be greater than or equal to 120f/p (f = rated frequency
Pr.01-01/01-35; P: number of motor poles Pr.05-04/05-16).

Permanent Magnet Motor (PM)

Set Pr.05-00= 5 or 13 and press 【Run】 to begin auto tuning for PM motor. The
measured values will be written into Pr.05-39（Rs）, Pr.05-40 & 41（Ld & Lq） and
Pr.05-43（PM motor＇s Ke parameter）.
To begin AUTO-Tuning for PM motor in rolling test:
1. Make sure all the parameters are reset to factory setting and the motor wiring installtion is
