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 frequency converter has been tested according to
a procedure based on the following standards:
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 frequency converter complies with requirements
that correspond to conditions when the unit is mounted
on the walls and floors of production premises, as well
as in panels bolted to walls or floors.
Air Humidity
The frequency converter 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.
