Material outage detection
The inverter automatically detects material outage through this parameter. This is a supplementary function, which
doesn’t apply to all situations. When not being able to get good results, set 14-37(P.637) to 0.
Material outage detection function 1:During operation, when using linear speed to calculate winding angle ,and
system linear speed is higher than 14-38(P.638), inverter will detect if there is an outage of material according to
winding radius change.
Material outage detection function 2:During operation,the inverter detects if there is a material outage according to
the position of the shaft.
When the system linear speed is higher than 14-38(P.638),winding radius error (the current winding radius
variation is too big compared to the previous winding radius) exceeds the range set in 14-39(P.639),and the error
time is over the delay time set in 14-40(P.640),the inverter reports material outage failure(bEb).
