    Diagnostic Procedures Trip codes Mnem. Code Reason for the trip Armature overcurrent An instantaneous protection trip has been activated due to excess current in the armature circuit Armature open circuit Drive has detected that the firing angle has advanced but no current feedback has been detected Current (control) loop open circuit If the input reference is either 4-20mA or 20-4mA, this trip indicates that input current is <3.0mA EEprom failure Indicates that an error has been detected in the parameter set read from the EEprom at power-up...

  • Page 99 Global Addressing The Mentor II Drive also supports the use of Global Addressing. This is where a message can be broadcast to all Drives on the network - to use this, the controller will send its message to address 00. Note that when global addressing is used, the Drives will not respond to any command messages.
