Setpoints 4 and 5
SK 540E and SK 545E frequency inverters can also process the 16 bit setpoints 4 and 5. The function
of these setpoints can be set in the inverter under the parameter 'Fct. Bus Setpoint 4' (P546 [-04]) as
well as 'Fct. Bus Setpoint 5' (P546 [-05]).
The value range and scaling corespond to setpoints 2 and 3.

4.1.6 Actual value (IW)
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 (or
P543 [-01]) 'Actual bus value 1'.
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) /digital
outputs can be transferred:
SK 300E/700E/750E
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
SK 5xxE
Bit Status
Bits 0-4 Digital input 1-5
Bit 5-6 (above SK 520E) Digital input 6-7
Bits 12-15 Relay and digital outputs 1 - 4
With the settings ‘Actual position’ and ‘Setpoint position’, the actual absolute position is transferred.
The resolution is 1 = 0.001 revolutions.
