Restrictions

• Volts per Hertz operation requires the use of the Custom User Defined Controller Communication Format.

If another Controller Communication Format is selected (e.g. Velocity Control, 

Position Control or User Defined Control) and the drive is configured for Volts per Hertz operation, 

the Drive Module will not connect to the controller.

• This module sometimes experiences PMI Comm faults during power cycles.

For example, when the Drive Module and PMI processor are power-cycled the drive module initializes its interface

with the PMI processor. During the transition from initialization to synchronized communication,

the Drive Module sometimes experiences communication faults and warnings. 

These faults and warnings can be cleared with a clear faults command. 

You may have to perform a reset after power-up, or perform multiple resets.

Local DH+ Messaging Devices use local DH+ messaging to communicate between devices on the same physical link.

A device that uses local DH+ messaging must: 

• generate local DH+ packets. 

• support local DH+ protocol. 

• send and receive messages. 

A local DH+ message sent on a DH+ network has only enough address information to get the message 

to a target node on the same DH+ network.
