Chapter 12 Description of Parameter SettingsC2000-HS
12.2-00-14
Parameter Description
Pr.05-35 Rated power (kW)
Pr.05-36 Rated rotor speed (rpm)
Pr.05-37 Number of poles for the motor (poles)
4. PM parameter auto-tuning:
Rolling auto-tuning for PM (without load) Pr.05-00=5 or static auto-tuning for PM
(Pr.05-00=13)
Set Pr.05-00=5 or 13 and press “RUN” key to finish motor auto-tuning, then you will get the
following parameters:
Parameter Description
Pr.05-39
Stator resistance for a permanent magnet motor (Ω)
Pr.05-40 Permanent magnet motor Ld (mH)
Pr.05-41 Permanent magnet motor Lq (mH)
Pr.05-43
Ke parameter of a permanent magnet motor (V
phase
，
rms
/ krpm)
(When Pr.05-00=5, the Ke parameter is measured based on the actual
motor rotation.)
(When Pr.05-00=13, the Ke parameter is automatically calculated based
on the motor power, current and rotor speed.)
If an auto-tuning error (AUE) occurs, refer to Section 14 “Fault Codes and Descriptions” for
further treatment.
AUE Error (code) Description
AUE (40) Auto-tuning error
AUE1 (142) Auto-tuning error 1 (No feedback current error)
AUE2 (143) Auto-tuning error 2 (Motor phase loss error)
5. Set encoder parameter
Check the encoder power and input type, make sure it is used with correct PG card.
PG Card Type
EMC-PG01L EMC-PG01O EMC-PG01U EMC-PG01R
EMC-PG02L EMC-PG02O EMC-PG02U -
Related parameters:
(1) Pr.10-00: Encoder type selection
(2) Pr.10-01: Encoder pulses per revolution
(3) Pr.10-02: Encoder input type setting = 1 (Phases A and B are pulse inputs, forward
direction if A-phase leads B-phase by 90 degrees)
6. Measure the initial magnetic pole angle of PM
(1) Set Pr.05-00=4 (dynamic test for PM magnetic pole)
(2) Press “RUN” key to proceed the PM magnetic pole measurement, and to get the offset
angle.
Note 1: It is suggested to measure the offset angle more than twice, to make sure the angle
tolerance is within ±5 degree.
Note 2: Verify the encoder and PG card are connected in the right order.
7. Cycle the power.
