The control of PMAC brushless motors is allowed if the relative position between the
stator and the rotor is well known. The resolver must be set up to define the relative
position between the resolver and the 3 motor phases. For the 890 drive, the
convention is as follows :
♦
when the motor runs in a clockwise direction, looking to the front shaft of the
motor, the 3 successive phases are M1, M2 and M3 as shown below.
♦
The resolver must be adjusted in a way to give a position of 0 degrees when the
M1 motor phase crosses the 0 Volt line in a rising variation. For example, a 6
pole motor associated with a 2 pole resolver will give the following curves:
-200
-150
-100
-50
