Rockwell Automation SA500 Drive Configuration and Programming - Manual (Page 98)

5-2 SA500 Drive Configuration and Programming
The option “A” for ALL will automatically load the rack (i.e., AutoMax Processor
configuration, the drive parameters for all the UDC modules in the rack, and all tasks
for the rack, including all UDC tasks).
The drive parameters may be loaded to the UDC module in a specified slot or to all
UDC modules in the rack. When the drive parameters are loaded, the AutoMax
Programming Executive will determine if the drive parameters are compatible with the
existing rack configuration. If the drive parameters are not compatible, an error
message will be displayed on the computer screen.
UDC tasks may also be loaded to the UDC modules in the rack. If this option is
chosen, the Programming Executive will display a list of all the AutoMax tasks and
UDC tasks for the system. Select the task to be loaded from the list. Note that the
rack configuration and the drive parameters must be loaded before loading UDC tasks
to a UDC module.
Refer to the AutoMax Programming Executive instruction manual for the complete
Load procedure.
5.3 Running, Stopping, and Deleting UDC Application
Tasks
Running UDC Tasks
A UDC application task is required in order to control a Distributed Power System
drive. To control two drives, two UDC tasks are required. Once it is loaded to the UDC,
a UDC application task is included in the on-line task list with the AutoMax Processor
application tasks. It can be run, stopped, monitored, or deleted in the same way as
any other application task. The priority field will be set to “N/A” for UDC application
tasks. The task for drive A always executes first, followed by the task for drive B.
The Run All command will run all AutoMax and UDC tasks. The UDC module’s tasks
can be run whether or not the following conditions are met:
• the PMI Regulator is communicating with the UDC module
!
ATTENTION: Understand the application before starting a task. Outputs
may change states, resulting in machine movement. Failure to observe
this precaution could result in bodily injury.
ATTENTION: Depending on the application, stopping an individual task
may result in loss of control of the application process. It is the
responsibility of the user to determine the potential hazards involved. It
is recommended that STOP-ALL be used to stop tasks normally. Failure
to observe these precautions could result in bodily injury.
ATTENTION: Variables and outputs which are forced before AC power
is lost will remain forced when AC power is restored. Should AC power
be lost while variables are forced, the user must ensure that unexpected
machine movement does not occur when AC power is restored. Failure
to observe these precautions could result in bodily injury.
ATTENTION: It is the responsibility of the user to ensure that the
application process stops in a safe manner when the application tasks
stop. Failure to observe this precaution could result in bodily injury.
