(wrong power connections) triggers, exchange two wires of the connection with the motor, e.g. U and
V, and then start the auto-tuning again.
At the end of the auto-tuning the displacement in degrees calculated by the system can be read in
P55
; this
value, for known motors with resolver, should differ only by a few degrees from the typical value of the table
given below. If not some connections are wrong with respect to the standard; e.g. if the difference is of the
order of ± 120° or ±240
º
, the connection of the drive with the motor power is probably wrong, while if the
difference is of the order of ± 60
º
or ±180
º
the resolver connection is probably wrong with or without errors
in the power.
Before switching off the mains, remember to store the parameters on the permanent memory c43=1
