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° )
