Configuration Parameters
This section describes for you in detail each of the Configuration
parameters available on the Discrete Adapter Board. All Configuration
parameters are 16-bit words. In order for a Configuration parameter to
affect system operation, it’s source and/or destination must be programmed
in the 1395.
Parameter 400 - [A > Digital Input]
300 - [B > Digital Input]
Use: Status of Discrete Input
Program 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 four 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 Set-Up Parameter
section.
Parameter 401 - [A > Analog In 1]
301 - [B > Analog In 1]
Use: Digital value of Analog Input 1 Signal
Program 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, Torque
Reference, Process Trim Reference, etc. 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.
Parameter 402 - [A > Analog In 2]
302 - [B > Analog In 2]
Use: Digital value of Analog Input 2 Signal
Program 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, Torque
Reference, Process Trim Reference, etc. Through programming of the
Set-Up configuration parameters a Scale Factor and Offset can be applied
to the input before it is displayed or transferred to the drive.
