Motor thermal protection
The motor temperature is calculated on the basis of
motor current, output frequency and time. See param-
eter 128 in the Operating Instructions.
Vibration and Shock
The adjustable frequency drive has been tested ac-
cording to a procedure based on the following stand-
ards:
IEC 68-2-6: Vibration (sinusoidal) - 1970
IEC 68-2-34: Random vibration broad-band
- general requirements
IEC 68-2-35: Random vibration broad-band
- high reproducibility
IEC 68-2-36: Random vibration broad-band
- medium reproducibility
The adjustable frequency drive complies with require-
ments that correspond to conditions when the unit is
mounted on the walls and floors of production prem-
ises, as well as in panels bolted to walls or floors.
Air Humidity
The adjustable frequency drive has been designed to
meet the IEC 68-2-3 standard, EN 50178 pkt. 9.4.2.2/
DIN 40040, class E, at 40°C.
