Rockwell Automation 1395 Digital Reference Adapter for RTP Applications - Manual (Page 55)

Publication 1395-RTP-5.2 - September 1997
Parameter Table 8-13
Description: This parameter determines the dancer full position logic
level for the Drive logic state machine. This is based upon the output
of the analog to digital converter of analog input #1 prior to analog #1
being digitally offset and scaled. The output of the converter will be 0
to 2048 corresponding to 0.0 volts to ±0.61 volts, nominally, of Dancer
potentiometer wiper voltage. This parameter sets the comparison value
of input # 1 above which the logic symbol, DFP = 1.
Parameter 559 – [A > Dancer Mid Position – Analog In #1]
Use: Determines a specific dancer position of analog input #1 Dancer
potentiometer wiper voltage.
Program Terminal Units: None
Maximum Value: 2048
Minimum Value: 0
Default Value: 750
Description: This parameter determines the dancer 3/4 full position
logic level for the Drive logic state machine. This is based upon the
output of the analog to digital converter of analog input #1 prior to
analog #1 being digitally offset and scaled. This parameter sets the
comparison value of input #1 below which or equal to the logic
symbol, DMP = 1.
Parameter 560 – [A> Dancer Center Position – Analog In #1]
Use: Determines a specific dancer position of analog input #1 Dancer
potentiometer wiper voltage.
Program Terminal Units: None
Maximum Value: 2048
Minimum Value: -2048
Default Value: 0000
Description: This parameter determines the dancer center position
logic level for the Drive logic state machine based upon the output of
the analog to digital converter of analog input #1 prior to analog #1
being digitally offset and scaled. This parameter sets the comparison
value of input #1 below which or equal to, the logic symbol, DCP = 1.
Parameter 561 – [A> Press Reference PPR – Digital Reference]
Use: Specifies the PPR of the reference encoder Program Terminal
Units: PPR
Maximum Value: 4096
Minimum Value: 100
Default Value: 131
Description: This parameter specifies the pulse per revolution of the
digital reference encoder. In this RTP Unwind Drive application, this
corresponds to the number of gear teeth on the magnetic pickup gear.
