6.2.11 Device overload monitoring (i*t)
The inverter calculates the i*t ulisaon in order to protect itself against thermal overload. In
simple terms: a higher current or an overcurrent that connues for a longer me causes a
higher i*t ulisaon.
DANGER!
Uncontrolled motor movements by pulse inhibit.
When the device overload monitoring funcon is acvated, pulse inhibit is set and the motor
becomes torqueless. A load that is connected to motors without a holding brake may there-
fore cause uncontrolled movements! Without a load, the motor will coast.
▶
Only operate the inverter under permissible load condions.
Details
The device overload monitoring funcon primarily oers protecon to the power secon.
Indirectly, also other components such as lter chokes, circuit-board conductors, and termi-
nals are protected against overheang. Short-me overload currents followed by recovery
periods (mes of smaller current ulisaon) are permissible. The monitoring funcon during
operaon checks whether these condions are met, taking into consideraon that higher
switching frequencies and lower stator frequencies as well as higher DC voltages cause a
greater device ulisaon.
•
If the device ulisaon exceeds the warning threshold set in 0x2D40:002 (default seng:
95 %), the inverter outputs a warning.
•
If the device ulisaon exceeds the permanent error threshold 100 %, the inverter is disa-
bled immediately and any further operaon is stopped.
•
Device overload monitoring depends on the inverter load characterisc 0x2D43:001
(P306.01).
•
The device overload can be obtained from the conguraon document.
