Notes: Externally excited input DC resistance must be greater than 17 Ω (can be measured
by a multimeter).Otherwise, RSI-PPVC-AXRY-ENPG-PG4 will not work normally.
It is recommended to select a resolver with a maximum of four pole-pairs.
Otherwise, RSI-PPVC-AXRY-ENPG-PG4 will be overloaded.

Description
Normal
None
Phase-lock loop unlocked
Phase lag of the resolver is very large.
Signal SIN/COS amplitude
exceeding the upper limit
D6 flashing is normally caused by interference. Ground the
motor well and connect the ground point of the resolver card
to PE of the drive.
Signal SIN/COS amplitude
too small
Generally, DB9 is not connected or not properly connected,
or wire is broken. If the preceding conditions do not occur,
check whether the resolver model selection is correct or not.
