*) In the SK 5xxE devices, the IW/SW 3/2 are assigned inversely to the words.

3rd word = IW/SW2, 4th word = IW/SW3

In the default setting, all receive PDOs are active. A decision is made when sending messages to the
applicable identifier whether one setpoint or up to three setpoints can be evaluated.

With transmit PDOs, only PDO 1 is active, while PDOs 2 to 4 are deactivated. If the application
requires the sending of several actual values, the corresponding PDO must be switched on. In the
following example, transmit PDO 2 is activated, the default setting transmits a status word and three
actual values. For this, the following messages must be sent via the SDO parameter channel (see
Section 4.3.4):

· Set the NMT status machine for the inverter to the state "Pre-Operational"
· Deactivate PDO 1 à SDO telegram (Index=0x1800 / Subindex=1 / Data=0xc0000181)
· Activate PDO 2 à SDO telegram (Index=0x1801 / Subindex=1 / Data=0x40000281)
· Set the NMT status machine for the inverter to the state "Operational"
· PDO 1 is deactivated to prevent the bus load from rising unnecessarily. The PDO is

activated/deactivated via Bit 31 in the corresponding parameter.
