The drive software also uses the setting of this parameter to decide
if the board is an MVS3007-4001 or an MVS3007-4002 type.
Therefore, it is important that this parameter be correctly configured.
7.4.5 Auto Configure P74.04
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 P74.04 to a 1. This would normally be the last step
during commissioning of the link.
For safety reasons the value of P74.04 is set to a default value of
zero.
7.4.6 Configure Link P74.05
Once the node address and PPO type have been entered, it is
necessary to instruct the firmware to update the PROFIBUS board’s
configuration. To do this set P74.05 to a 1. 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 P74.04 was set to a 1 prior to a power-up, setting P74.05 to a 1
will not change the node address until the power is cycled.
If pointer and scale parameters are changed, a 'configure' link
operation is required before the new values are utilised. In this
case there is no requirement to power-cycle the drive.
