AC890PX AC Drive
Functional Description
The convention in the 890 drive is given below :
0 50 100 150 200 250 300 350 400
U phase
V phase
W phase
The correct succession of motor phases is U ( or M1 ), V ( or M2 ), W ( or M3 ) if the motor rotates in a clockwise direction
looking to the motor shaft on the front side. U phase must ride through the 0 point in a positive way at a position of 0°
(electrical position). The position must also increase in that direction.
To polarise the motor, a current setpoint is ramped to the motor in a special configuration. This will cause the rotor to lock to a
specific position.
