Parameterization
of frequency converter
without running motor
Normally the converter is under tension as soon as the I-key (On) is pressed
and the compressor motor starts. In case the frequency converter has to be
parameterized during motor stand-still – you only have to press the
↵
-key
– when the main display is shown – and the compressor is switched off.
Then the converter supply contactor starts up and the motor remains in stand-
still – the green LED is not illuminated.
By pressing the O-key (Off) the converter supply contactor drops out.
