Programming Parameters
5-9
Parameter 452 – [A > Analog Out 2]
Parameter 352 – [B > Analog Out 2]
Use : Digital value of Analog Output 2 Signal
Programming Terminal units: None
Minimum Value: –32767
Maximum Value: 32767
Default Value: None
Description: This parameter is a Fast Sink used to convert a
±
32767
digital value to a
±
10V DC output. This digital value can then be linked
to one of the Drive input parameters such as Velocity Feedback,
Armature Current feedback, Flux Command, etc. Through programming
of the associated Set-Up parameters a Scale Factor and Offset can be
applied to the output before it is converted to the analog signal.
Parameter 453 – [A > Dig Mult Fast]
Parameter 353 – [B > Dig Mult Fast]
Use : A fast parameter used to apply a multiplier value against the
digital reference.
Programming Terminal units: None
Minimum Value: –16000
Maximum Value: 16000
Default Value: None
Description: This parameter is a Fast Sink which can be used to apply a
multiplier against the digital reference input. The Digital Mult Fast
value is divided by 1000 and then multiplied to the Digital Reference
Value. The Digital Multiplier Select parameter (P569) determines
whether the multiplier value comes from this parameter or the Digital
Multiplier Constant Parameter (P568). The difference is that this
parameter is a Fast parameter and the multiplier constant parameter is a
Slow parameter.
Parameter 454 – [A > Dig Output 2]
Parameter 354 – [B > Dig Output 2]
Use : Status of Digital outputs
Programming Terminal units: None
Description: This parameter is a Fast Sink used to transmit the status of
up to five discrete bits of data from the 1395 drive to the solid state
outputs on the Adapter Board. The digital outputs can be mapped to any
of the 16 bits in this parameter. Typically, this would be used for cases
where outputs from a source other than logic status are required. The
digital outputs are updated every 20 milliseconds.
