Network Loss Trip

Unidrive:

If the DeviceNet 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 4.9.

4.9

UD70 (#17.PP) and DeviceNet (#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. See section 5.5.2 for details on how to store UD70

parameters.
