Antenna motors - power consumption

When the power consumption figures for a DiSEqC dish motor are quoted, does these figures include the power drawn by the LNB itself?

eg. A Fortec Star HH42 is quoted as drawing:
50mA (Standby Mode)
200mA(Normal)
350mA (Max.)

But a typical LNB can draw 120mA - leading to a possible total consumption of up to 470mA (one of my receivers is rated at just 400mA maximum).

Also, what is meant by the three modes - standby, normal and max?

Thanks,
Jamie.
