If the query is faulty, the response in byte 0 = 0x80.
4.5.4.5 Cancelling of parameter communication
If problems occur during parameter communication (e.g. value range overflow), a cancel telegram is sent. This
can be recognised by the number 0x80 in byte 0. The cause of the cancellation is indicated in bytes 4 to 7.

Example of error message ( 0x06010002 = Access to read-only object)
A list of all possible error codes is contained in Section 4.9.5 "Error codes – cancellation of parameter
communication"
4.6 Timeout monitoring
Various timeout monitoring modules can be defined. Details of these are described in Section 6.1.1 "Error
monitoring details".
4.7 Saving the parameters
If the CANopen bus module is accessed via RS232 (e.g. via NORDCON software or the ParameterBox), the
parameter changes are saved in the EEPROM immediately. Loading of the factory settings can be carried out
via parameter (P152).
For changes to module parameters via the CANopen bus, 0x1010 Subindex 1 is used to save the parameter.
Restoration of default values is possible via 0x1011 Subindex 1.
4.8 Special features of CANopen communication
The DSP402 drive profile is only implemented in the field bus modules (SK xU4-CAO).
Broadcast operation is not possible via the CANopen field bus modules (SK xU4-CAO). This can only take
place directly between the frequency inverters at system bus level or with direct connection of the frequency
inverter to the CANopen field bus.
