4.3.1 Network Management (NMT)

The individual states of the CANopen network can be activated with the following commands:

Status

Description

Commands for setting the

operational state

Pre-Operational

The inverter enters this state after initialisation. This
state is used for bus module configuration. Data traffic
via SDO objects is possible. The PDO channel is
blocked.

Identifier = 0x00 // Data byte 0
= 0x80 // Data byte 1 = 0x00

Operational

The bus is fully operational, SDO and PDO objects can
be transmitted

Identifier = 0x00 // Data byte 0
= 0x01 // Data byte 1 = 0x00

Stopped

Transfer of SDO and PDO objects is blocked, only NMT
messages can be transferred

Identifier = 0x00 // Data byte 0
= 0x02 // Data byte 1 = 0x00

4.3.2 Drive profile DS 402

Together with the module SK TUx-CAO the frequency inverter supports the drive profile DS 402
Velocity Mode (speed profile).

The profile is only valid in parameter set 1 and is activated via parameter (P551).

Figure 10: Velocity Mode CiA DSP 402 V1.1 page 178

Information

Drive profile DS 402

When the drive profile is activated (P551 = On), objects 6040 - 6044 instead of 3000 - 3003 are relevant.

The drive profile is not supported if the CANbus is implemented via the integrated RJ 45 sockets for SK 5xxE
inverters.

4.3.3 Process data transfer in CANopen mode (PDO communication)

PDOs (Process Data Objects) are used for transferring process data.

Table 14: PDO types

NORD frequency inverters have up to 4 transmit and 4 receive PDOs which are identified by different
identifiers.

Transfer of PDOs is made without confirmation. The significance of the data transferred is determined
by the CAN identifiers being used and the PDO mapping. A maximum of 8 bytes of data is transferred.
