Network Loss Trip

Unidrive:
If the Profibus-DP network stops operating, the interface will trip the
Unidrive on "tr60". The default time delay between network loss and
Unidrive trip is 48ms, so the actual delay to trip will be between 48ms
and 96ms. (See section 9.1 for more details.) The master controller
will automatically detect that the slave node has gone missing from the
network, and will update relevant status registers.
NOTE
Changes to #17.PP parameters in the Unidrive do not take effect until
the UD70 has been reset. See section 4.7.

Initialising Set-up Changes

UD70 (#17.PP) and Profibus-DP (#20.PP) configuration parameters are
only read during the initialisation sequence of the UD70. This prevents
corruption of the configuration while parameters are being edited.
When parameters have been configured, the UD70 must be reset to
implement any changes made to the configuration parameters.
To reset from the UD70, set #MM.00 to 1070, and press the red RESET
button on the Unidrive.
configuration will now take effect.
NOTE
Resetting the UD70 does not store the #20.PP configuration
parameters, so these changes will be lost when the Unidrive is
powered down.
