■ Set parameters of resolver
Table 3-2. Parameters of resolver
(1) <F397: Resolver carrier frequency> is the excitation carrier frequency of resolver signal.
(2) Set <F376: PG select> to “3” when polarity is positive, or “13” when polarity is negative.
(3) <F377: PG option disconnection detection>=“1” : in case resolver is not connected, or resolver at least one phase is
missed, “E-12” trip occurs. (<F376> should be set for Resolver)
It is necessary to reset the inverter power to enable the changes.
(4) Use resolver with transformation ratio = 0.5
(5) Use resolver with 2 poles
