10

0

MFR 1 reference value
undershot

Programmed function of the MFR 1 not met or 
 actual value < programmed
reference value

1

MFR 1 reference value
reached

Programmed function of the MFR 1 is fulfilled, or
Actual value > programmed reference value

13

0

MFR 4 reference value
undershot

Only for SK 700E/750E with POSICON extension: Status MFR 4 = 0

The setpoint is transferred as a whole number with a value range of -32768 to 32767 (8000 hex to 7FFF hex).
The value 16384 (4000 hex) is equal to 100%. The value C000 HEX corresponds to -100%. A setpoint of
100% corresponds to the parameter maximum frequency (parameter P105) set in the same parameter set.
