KEB COMBIVERT F5 Instruction Manual page 19

Change rotation
Now the motor is excited with its rated current and aligned to its zero
position. The adjustment is finished when the displayed system position
at CP.20 does not change for approx. 5 s. In this case open control
release and switch off the unit.
If the error message E.EnC is displayed during trimming the direction of
rotation must be checked (CP.21). In this case the position trimming must
be repeated.
In case that motors with aligned encoder system are used, the value
which has been established by the automatic trimming, can be entered
under CP.20 as well. The adjustment values of known motors of the KEB
COMBIVERT S4 series must be multiplied by the pole-pair number of the
motor.
Example 1: A 6-pole motor (3 pole pairs) has a system position of
19.019 dec. with a S4-servo controller.
19019 dec.
4A4Bh x 3 pole pairs =
DEE1h
If the value exceeds 65535 dec., the lower 16 bit of the hexadecimal result
must be entered.
Example 2: A 6-pole motor (3 pole pairs) has a system position of
23497 dec. with a S4-servo controller.
23497 dec.
5BC9h x 3 pole pairs =
1135Bh
135Bh

Resolution:
Factory setting:
The speed display at CP.1 must be positive when the engine runs manual
in clockwise direction. The signals SIN+ and SIN- of the resolver have to
be changed, if the sign is wrong. Please ensure that the signals are not
short-circuited with the internal shield (see connection resolver).
Should this involve too much effort then you can achieve a rotation
reversal of encoder 1 by means of this parameter.
