8.5.4 Run On Power Up P75.04
WARNING
The user should be aware that allowing the PROFIBUS link to
automatically configure and run on power up could represent a
possible safety hazard, as the data from the network will be
acted on by the Drive.
Many users may require the PROFIBUS link to be automatically
configured and run as the drive powers up. This option is available
by setting P75.04 to a 1. This would normally be the last step during
commissioning of the link.
For safety reasons the value of P75.04 is set to a default value of
zero.
8.5.5 Configure Link P75.05
Once the node address has been entered, it is necessary to instruct
the firmware to update the PROFIBUS board’s configuration.
Setting P75.05 to a 1 does this. The firmware automatically rewrites
this value to a zero when configuration is complete. Only after this
occurs will any changes to the board’s configuration take effect.
The PROFIBUS node address can only be reconfigured once
per power up. If the node address needs changing, the new
node address must be programmed and then the drive power
cycled.
If P75.04 was set to a 1 prior to a power-up, setting P75.05 to a 1
will not change the node address until the power is cycled.
8.5.6 Source Loss Action P75.06
A loss of reference may be declared if the PROFIBUS link detects a
loss of communications with the master.
When a loss of reference is declared, one of three things can
happen depending upon the state of P75.06. Valid values of P75.06
are:
0
Ignore loss of reference errors and carry on running.
