Chapter 12 Description of Parameter SettingsMH300
Parameter Description
Pr.05-36 Rated rotor speed (RPM)
Pr.05-37 Number of poles for the motor (poles)
4. PM parameter auto-tuning:
Set Pr.05-00 = 5 (rolling auto-tuning for PM, with no load) or 13 (static auto-tuning for PM)
and press RUN key to finish motor auto-tuning, then you will get the following parameters:
Stator resistance for a permanent magnet motor (Ω
)
Permanent magnet motor Ld (mH)
Permanent magnet motor Lq (mH)
Pr.05-43
Ke parameter of a permanent magnet motor (V
phase
,
rms
(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 Chapter 14 “Error Codes and Descriptions” for
further treatment.
AUE (40) Auto-tuning error
Auto-tuning error 1 (No feedback current error)
Auto-tuning error 2 (Motor phase loss error)
Auto-tuning error 3 (No-load current I
0
Auto-tuning error 4 (Leakage inductance Lsigma measuring 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-PG01R
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 (A-phase and B-phase 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. Re-power on after power off.
8. Execute inertia estimation for PM
(1) Set Pr. 00-11 = 4, PM FOCPG control.
(2) Set the operation frequency command to 2/3 of the motor’s rated frequency.
(3) Set the acceleration / deceleration time (Pr. 01-12, Pr. 01-13) to 1/10 of the default time.
