Programming Parameters
5-7
Parameter 402 – [A > Analog In 2]
Parameter 302 – [B > Analog In 2]
Use : Digital value of Analog Input 2 Signal
Programming 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 such as Velocity Reference,
Process Trim Reference and Torque Reference. Through programming
of the associated Set-Up parameters a Scale Factor and Offset can be
applied to the input before it is displayed or transferred to the drive.
Parameter 403 – [A > Dig Ref Whole]
Parameter 303 – [B > Dig Ref Whole]
Use : Digital Value of the Whole Portion of the Digital Reference Input.
Programming Terminal units: None
Minimum Value: –32767
Maximum Value: 32767
Default Value: None
Description: This parameter is a Fast Source used to convert the whole
part of the Digital Reference signal to a
±
32767 digital value. This value
can then be linked to one of the Drive input parameters such as Velocity
Reference Whole or Process Trim Reference etc.
Parameter 404 – [A > Digital Ref Fractn]
Parameter 304 – [B > Digital Ref Fractn]
Use : Digital value of the fractional portion of the digital reference
input.
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 65535
Default Value: None
Description: This parameter is a Fast Source used to convert the
fractional part of the Digital Reference signal to a 0 – 65535 digital
value. This value can then be linked to one of the Drive input
parameters such as Velocity Reference Fraction.
