MOT CURRENT RAMP
To start the STANDARD polarisation:
1.
The motor must be stationary, with no load attached to the motor shaft. In this method, there will be a maximum movement of half an
electrical turn of the motor shaft.
2.
Choose a MOTOR PHASE: U, V or M.
3.
Set the current level to apply in the MOT CURRENT PCNT parameter.
4.
Set a ramp value for the current level in the MOT CURRENT RAMP parameter.
5.
Set POLARISATION = ENABLE, POLAR START = FALSE.
6.
Verify that ELEC POS OFFSET is set to 0.0.
7.
Set POLAR START = TRUE.
8.
Apply a torque to the motor and read the value of the ELEC POS parameter.
9.
Stop the motor. Verify that the value of ELEC POS after polarisation matches the theoretical position for the chosen motor phase :
♦
U or M1 :
90°
♦
V or M2 :
210° ( -150° )
♦
W or M3 : 330° ( -30° )
If not, apply a compensation using the ELEC POS OFFSET parameter. If necessary, repeat steps 6 and 7 until an error of only 1° to 5° is
achieved.
