Rockwell Automation 1395 Digital Reference Adapter for RTP Applications - Manual (Page 48)

Publication 1395-RTP-5.2 - September 1997
8-6 Parameter Table
Configuration Parameters This chapter describes in detail each of the Configuration parameters
available on the Digital Reference Adapter Board. All Configuration
parameters are 16-bit words. In order for a Configuration parameter to
affect system operation, its source and/or destination must be
programmed in the 1395.
Parameter 400 – [A > Digital Input]
Use: Control transfer from state machines to logic command
Program Terminal Units: None
Description: This parameter is a Fast Source used to transmit the
control of the Drive logic state machine and the Drive reference
control state machine to the bit packed word of logic command #2.
The internal state machines are controlled by a logical combination of
the eight inputs and the three zones of the Dancer potentiometer.
Parameter 401 – [A > Analog In 1]
Use: Digital value of Analog Input 1 Signal
Program Terminal Units: None
Minimum Value: -32767
Maximum Value: 32767
Default Value: None
Description: This parameter is a Fast Source used to convert a ±10V
DC signal to a ±32767 digital value. This digital value can then be
linked to one of the Drive input parameters, Process Trim Reference.
Through programming of the Set-Up Parameters a digital Scale
Factor and digital Offset can be applied to the input before it is
displayed or sent to the Drive.
Parameter 402 – [A > Analog In 2]
Use: Digital value of Analog Input 2 Signal
Program Terminal Units None
Minimum Value: -32767
Maximum Value: +32767
Default Value: None
Description: This parameter is not used in the RTP Unwind Drive
application. This parameter is a Fast Source used to convert a ±10V
DC signal to a ±32767 digital value. This digital value can then be
linked to one of the Drive input parameters such as Velocity
Reference, Torque Reference, Process Trim Reference, Etc. Through
programming of the Set-Up Configuration parameters a digital scale
factor and digital Offset can be applied to the input before it is
displayed or transferred to the Drive.
