Figure 32. Belt Failure Detection without Sensor (P2181).
This function allows for monitoring power transmission components such as drive belts. The
function can also detect motor overload, such as in the case of a jam.
The actual frequency/torque curve is compared to a preprogrammed tolerance band (see P2182
through P2190 in the Appendix A: Parameter Reference List of this document) as part of this
function. If the actual curve is outside the tolerance band, a warning or error message (F0085)
occurs.
