4.1 Device commands (C00002/x)
This chapter describes the device commands of the inverter which are provided in the subcodes of
C00002
and can be carried out using the keypad or, alternatively, the »Engineer« when an online
connection has been established.
The device commands serve, among other things, to directly control the inverter to organise
parameter sets, and to call diagnostic services.
Regarding the execution of the device commands, a distinction is drawn between:
• Device commands which have an immediate effect on control (e.g. "Activate quick stop")
• After being called in C00002/x
, these device commands provide static status information
("On" or "Off).
• Device commands with longer execution duration (several seconds)
• After being called in C00002/x
, these device commands provide dynamic status information
("Work in progress 20%"  "Work in progress 40%", etc.).
• The execution of the device command has not finished successfully until the "Off / ready"
status information is provided in C00002/x
.
• In the event of an error, the "Action cancelled" status information is provided in C00002/x
. In
this case, further details can be obtained from the status of the device command executed
last which is displayed in C00003
.
 Stop!
Before the supply voltage is switched off after a device command has been transmitted
via C00002/x
, the device command must be checked for successful completion on the
basis of the status information provided in C00002/x
!
• This is of particular importance for device commands which save data to the memory
module of the device. Incomplete storage processes may lead to data inconsistencies
in the memory module.
 Note!
• Before activating device commands by a master control, wait for the "Ready" signal of
the inverter.
• The device will reject a write process to C00002/x
if the value is >1 and issue an error
message.
• C00003
displays the status of the device command that was executed last.
