Rockwell Automation 1395 Digital Reference Adapter for RTP Applications - Manual (Page 49)

Publication 1395-RTP-5.2 - September 1997
Parameter Table 8-7
Parameter 403 – [A > Digital Reference Input (Whole)]
Use: Digital value of the whole portion of the Digital Reference
Input.
Program Terminal Units: None
Minimum Value: -32767
Maximum Value: 32767
Default Value: None
Description: This parameter is a Fast Source used to connect the
digital reference generated in the Adapter Board from the encoder
input, to normally, the external velocity speed reference – whole part
of the main control board.
Parameter 404 – [A > Digital Reference Input (Fractional)]
Use: Digital Value of the fractional portion of the Digital Reference
input.
Program Terminal Units: None
Minimum Value: -32767
Maximum Value: 32767
Default Value: None
Description: This parameter is a Fast Source used to connect the
digital reference generated in the adapter board from the encoder
input, to, normally, the external velocity speed reference – fractional
part of the Main Control Board. The fractional part of the reference
aids in the resolution of the reference near zero speed.
Parameter 405 – [A > Torque Reference Select]
Use: Permits the Drive logic and reference control state machines to
select the normal velocity regulator or zero torque reference in the
RTP Unwind Drive application.
Program Terminal Units: None
Minimum Value: 0
Maximum Value: 5
Default Value: 1
Description: This parameter is a Fast Source used to connect the
machine logic to parameter 625 of the Main Control Board. This
allows zero torque reference during the auto slack loose state – mode
8. At all other times the velocity regulator maintains the torque
reference. (See Parameter 625 in the 1395 Digital DC Motor Drive
manual.)
Parameter 406 – [A > Digital Input Auxiliary]
Use: Status of Discrete Input
Program Terminal Units: None
