Configuration Parameters
This reference section describes in detail each of the Configuration
parameters available on the Digital Reference Adapter Board when
installed in either Port A or Port B. The parameters for Port B are shown
below the corresponding Port A parameters. All examples given are for
Port A All Configuration parameters are 16 bit words. In order for a
Configuration parameter to affect system operation, some of the sources
and /or destinations have been preprogrammed in the 1395.
Review all parameters and values for your specific application, if not
applicable they can be reconfigured accordingly.
Parameter 400 – [A > Digital Input 1]
Parameter 300 – [B > Digital Input 1]
Use : Status of Discrete Input
Programming Terminal units: None
Description: This parameter is a Fast Source used to transmit the status
of the four digital inputs on the Adapter Board to the Drive. The ten
digital inputs can be mapped to any of the 16 bits in this parameter.
Typically, this parameter is linked to one of the Logic Commands in the
drive which allows for Start, Stop and Jog Control. The actual bit
mapping is determined by the Set-Up parameters explained in the next
section.
Parameter 401 – [A > Analog In 1]
Parameter 301 – [B > Analog In 1]
Use : Digital value of Analog Input 1 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 sent to the drive.
