3.2 Motor Trail Run
3.2.1 Set motor parameters of group F1˄F1-00 to F1-05ˈF1-15˅
3.2.2 Set pole-pairs number of the rotary encoder
3.2.3 Set the drive to non-oil pressure control mode˖A3-00 ˙Ā0ā
3.2.4 Set the drive to operation panel control mode, at this time the light of LOCAL/REMOT is
off.
3.2.5 Motor parameter tuning( automatic identification) ˄F1-16˅
F1-16˙Ā0ā: No operation. It doesnÿt conduct the motor parameters tuning.
F1-16˙Ā1ā: Static tuning. Adopt when the motor back EMF is known. Run the motor at the
low speed without opening the overflow valve during tuning.
F1-16˙Ā2ā˖Dynamic tuning. Adopt it when the motor back EMF is unknown. Run the motor
at the high speed with opening the overflow valve during tuning. Carrier tuning will affect the
precision of the motor parameters tuned, affecting the system control effectiveness.
a)If correctly set F1 group motor parameters (F1-00 to F1-05ǃF1-15)and the rotary encoder
number of pole-pairs(A1-04), just only conduct F1-16˙Ā1ā(static tuning).
b) If it is only able to correctly set F1 group motor parameters (F1-00 to F1-05), rotary encoder
number of pole-pairs (A1-04) was unable to determine the F1-15 (back EMF), you must
conduct F1-16 =āĀ1ā(dynamic tuning).
The numerical value of parameter F1-16 will restore to zero automatically after tuning.
If the drive alarm Err43 in the tuning process, it indicates that the encoder feedback signal is
wrong, please check the encoder signal wiring and installation precision.
3.2.6 When at trial run, set running frequency (F0-08), run by using the operation panel, while
detecting whether the output current is normal, whether the motor is running quietly, and the
way of using the operator .Please refer to the operation and display of Chapter 4.
Look into whether the running direction of the drive is correct, if it is correct, please swap motor
wiring arbitrary two-phase UVW and recheck motor parameters tuning. Then trial run.
If there is abnormal running, please check the motor parameters (F1 groups) and rotary
encoder number of pole-pairs (A1-04) setup, and then restart the motor parameters tuning,
then trial run.
Motor has oscillation when running or sends a low voice, please weaken the speed
loop(F2-00ǃF2-01ǃF2-03ǃF2-04) and current loop(F2-13ǃF2-14ǃF2-15ǃF2-16)
appropriately˄reduce the value of F2-00ǃF2-03ǃF2-13ǃF2-14ǃF2-15ǃF2-16ˈincrease
the value of F2-01ǃF2-04˅.
Motor running speed is not steady, please enhance speed loop(F2-00ǃF2-01ǃF2-03ǃF2-04)
and current loop(F2-13ǃF2-14ǃF2-15ǃF2-16) appropriately.(Increase the value of F2-00ǃ
F2-03ǃF2-13ǃF2-14ǃF2-15ǃF2-16.Reduce the value of F2-01ǃF2-04)
NOTE: The slow response of the speed and current loop will affect the pressure stability
directly, if the condition allows, please set the stronger speed loop and current loop response.
