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:

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

The actual value 1 (IW1)
The actual value 1, i.e. the actual output frequency of the inverter, is transferred as a 16 Bit value as standard
in the actual value 1. The actual value 1 is transferred to the master in the inverter response telegram as the
second word in the process data area.

The actual value 1 is transferred as a whole number in the range (-32768 to 32767). In addition to the actual
frequency, other actual inverter values can be transferred. The setting is made in P543 'Actual value 1
function
'.
The settings ‘Actual frequency’, ‘Actual speed’, ‘Current’ and ‘Torque current’ are transferred as percentages of
the respective nominal values. The value 16384 (4000 HEX) corresponds to 100%. The value C000 HEX
corresponds to -100%. Actual values in the range –200% to +200% can be transferred.
With the setting ‘Digital I/O status’, the states of the control terminals and the relay (MFR) can be transferred:
Bit
Status
Bits 0-5
Digital input 1-6
Bit 6-11 for posicon special extension unit Digital input 7-12
Bit 6 for encoder special extension unit
Digital input 7
Bits 12-15
Multifunctional relay 1-4
With the setting 'Actual position' and 'Setpoint position' the actual absolute position is transferred. The
resolution is 1 = 0.001 revolutions. If the value 'Setpoint position 32 Bit' is set in parameter P546 (Function
setpoint 1
), then the actual value (Setpoint or actual position) is also transferred to IW2 and IW3 as a 32 Bit
value.
