5.4 Fine tuning the resolver angle
Step Action Note
1 Drive the elevator with full speed in the
heavy direction (always between the
same levels).
2 Record the values of
Resolver angle
(6_61)
and Motor torque
measurement (6_71)
.
Motor torque measurement (6_71) is
the average value of the TORQ signals.
It is a “read only” value.
3 Return the elevator back to the starting
level.
4 Increase the value of the
Resolver
angle (6_61)
by 5°.
5 Repeat steps 1-3.
6 Compare the two motor torque values. If the value of the second run is lower
than the first one, Resolver angle
(6_61)
value must be increased.
If the value of the second run is higher
than the first one,
Resolver angle
(6_61)
value must be decreased.
7 Increase/decrease the
Resolver angle
(6_61)
by 5°.
8 Repeat the drive in the heavy direction.
9 Record the values of
Resolver angle
(6_61)
and Motor torque
measurement (6_71)
.
10 Return the elevator back to the starting
level.
11 Compare the values of two last
recorded
Motor torque measurement
(6_71)
.
12 Repeat steps 7-11 until you have found
the lowest value for the
Motor toque
measurement (6_71)
.
Typical value is < 0.9 (the lower value
the better).
13 Set the
Resolver angle (6_61) to the
value where the
Motor torque
measurement (6_71)
is lowest.
