Selection of resolver must satisfy parameter setting requirement of
Note
MD38PG4. Especially excited input DC resistance must be larger
than 17 Ω (can be measured by multimeter). Otherwise, MD38PG4
cannot work normally.
●
It is suggested to select a resolver with a maximum of four pole-pairs.
Otherwise, MD38PG4 will be overloaded.

GT60PG4 Fault State Description
Signal SIN/COS Generally, DB9 is not connected or
amplitude too small wrongly connected, or even wire breaks.
If the preceding conditions do not occur,
check whether the resolver matches
GT60PG4.
Phase-lock loop Phase lag of the resolver is very large.
unlocked
Signal SIN/COS It is caused by interference. Ground the
amplitude exceeding motor well and connect the ground point
the upper limit of the resolver card to PE of the drive.
