
Speed setting analog loss is not detected before running. If the sampling value of the
analog given by the speed is less than the lower threshold or over than the upper
threshold，speed setting analog loss fault is generated


When the consecutive lost signal of encoder is higher than speed error threshold for
encoder fault(P0398), or the error between encoder speed and estimated speed is
higher than P398, or the encoder signal loss rate per cycle is higher than loss ratio
threshold of encoder fault(P1083), encoder abnormal fault is generated.

External Fault

Connect external fault signal wiring to DI of PLC. The switching node should be normal
open. While the switching node is closed, external fault is generated.
