Shock Monitoring Function - Toshiba TOSVERT VF-S15 Instruction Manual

1. Introduction
TOSVERT VF-S15 is equipped with shock monitoring function.
In case output current or torque exceeds or lowers the set level for a certain amount of time, the inverter
outputs the alarm signal from output terminals or trips (inverter stops). Temporary change in current or
torque can be eliminated from detecting conditions.
Shock monitoring function enables monitoring the load side and protecting the equipments in case of load
abnormality including the detection of excessive loading of conveyors and breakage of conveyor belt.

2. Shock monitoring function

When output current or torque exceeds or lowers the set level for a certain amount of time, shock
monitoring function outputs alarm signal from the output terminals or the inverter trips.
Over-torque trip/ alarm and small current trip/alarm have similarly functions as the shock monitoring
functions. The difference is as described below;
