Deviations in the status word (ZSW) for SK 300E and SK 700/750E series devices
With the above device types, the meanings of the two bits 10 and 13 in the status word deviate from the status
word of the SK 500 E.
Meaning of the two individual bits:
Bit Value Significance Comments
10 0 MFR 1 reference value
undershot
Programmed function of the MFR 1 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 upgrade: Status MFR 4 = 0
1 MFR 4 reference value
reached
Only for SK 700E/750E with posicon upgrade: Status MFR 4 = 1
6.4.5 The setpoint 1 (SW1)
The function of the 1st setpoint is set in parameter P546. The following options are available:
6.4.5.1 Setpoint frequency
The setpoint frequency in setpoint 1 is transferred as a 16 Bit value as standard. Setpoint 1 is transferred to
the inverter as the second word in the process data area in the order telegram.
PZD1 PZD2 PZD3 PZD4
STW SW1 SW2/3 SW3/2
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 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.
