AKD Benutzerhandbuch | 25.20.4 FBUS.PROTECTION
When the fieldbus is operational the AKD uses the FBUS.PROTECTION parameter to allow the user
to select how commands from WorkBench, or any other device sending commands to the drive
through a service channel, should be handled. WorkBench can use either of two service channels: Tel-
net or ASCII SDO. Both service channels are affected identically by FBUS.PROTECTION.
The following table shows the available options. If the fieldbus is not connected or not started, then
parameters executed through a service channel will not be blocked.
Value Description
Motion and Tuning Commands Allowed - Commands that would interfere with motion are
0
allowed. Gain and IO configuration changes are allowed.
Block Motion but Allow Tuning Commands - Commands that would interfere with
1
motion are blocked. Gain and I/O configuration changes are allowed.
DRV.HELP will include the [Blocked] attribute to indicate whether a parameter is being blocked. For
example, if FBUS.PROTECTION is 0 and the network is operational, the following help will be shown.
-->DRV.HELP DRV.EN
Help for: DRV.EN [ActionCommand] [Blocked]
-->
If you attempt to execute a blocked parameter the following error would display.
-->DRV.EN
Error: [0008] Command blocked.
All write or command functions of a parameter will be blocked by FBUS.PROTECTION.
FBUS.PROTECTION will not block the read function of any parameter.
When the fieldbus is operational, FBUS.PROTECTION is always blocked, but can be edited through
the fieldbus. This ensures that the protection level can only be modified by the fieldbus when it is in
control.
If a parameter is blocked through telnet, it will be accessible through the fieldbus. For example, SDO's
in the case of CANopen or EtherCAT.
Parameters Affected by FBUS.PROTECTION
This table shows how the blocked attribute affects the following parameters in each state of
FBUS.PROTECTION. This table is true only if FBUS.STATE = 5 (operational).
