Appendix
Special technical data
The following tables show the technical data of the frequency
inverter M-Max
TM
in the individual power classes with the
allocated motor output.
Device series MMX11
h
The motor output allocation is based on the rated
operational current.
h
The motor output designates the respective active power
output to the drive shaft of a normal, four pole, internally
or externally ventilated three-phase asynchronous motor
with 1.500 rpm at 50 Hz or 1.800 rpm at 60 Hz.
