Programming Parameters
5-15
Parameter 563 – [A > Digital Ref PPR]
Parameter 513 – [B > Digital Ref PPR]
Use : Specifies the pulse revolution of the reference encoder.
Programming Terminal units: PPR
Minimum Value: 100
Maximum Value: 32767
Default Value: 1024
Description: This parameter specifies the pulse per revolution of the
digital reference encoder.
Parameter 564 – [A > Digital Ref Scale]
Parameter 514 – [B > Digital Ref Scale]
Use : Specifies the maximum revolutions per minute of the reference
encoder.
Programming Terminal units: RPM
Minimum Value: 100 – 6000
Maximum Value: (–100) – (–6000)
Default Value: 1750
Description: This parameter specifies the speed tracking of the digital
reference encoder in the application. The sign of the parameter allows
the sign inversion of the digital reference output to the Main Control
Board.
Parameter 565 – [A > Digital Ref Offset]
Parameter 515 – [B > Digital Ref Offset]
Use : Sets minimum speed of the digital reference.
Programming Terminal units: None
Minimum Value: +1024
Maximum Value: –1024
Default Value: 0
Description: This parameter sets the minimum speed of the digital
reference (1024 means 25% of base speed). This offset is added to the
filtered value prior to the reference being transferred to the Main
Control Board.
Parameter 566 – [A > Digital Ref Filter]
Parameter 516 – [B > Digital Ref Filter]
Use : Specifies the value of the output filter
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 8
Default Value: 0
Description: This parameter specifies the amount of output filtering of
the digital reference that occurs prior to the reference being transferred
to the Main Control Board. As the parameter is increased from 1 to 8,
the effectiveness of the filter is increased, (i.e., the filter fixed frequency
lag is lowered). The time constants have a range as follows: 1 = 58
milliseconds and 8 = 1024 milliseconds, 0 = no filtering.
