Parameter Table
8-8
Parameter 403 - [A > Analog In 3]
303 - [B > Analog In 3]
Use: Digital value of Analog Input 3 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 transferred to the drive.
Parameter 404 - [A > Analog In 4]
304 - [B > Analog In 4]
Use: Digital Value of Analog Input 4 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 transferred to the drive.
Parameter 450 - [A > Digital Output]
350 - [B > Digital Output]
Use: Status of Digital Outputs
Program Terminal Units: None
Description: This parameter is a Fast Sink used to transmit the status of
two discrete bits of data from the 1395 to the relay outputs on the Adapter
Board. The two digital outputs can be mapped to any of the 16 bits in this
parameter. Typically, this parameter is linked to Logic Status in the 1395
which allows for indication of Drive Running, At Zero Speed, Drive
Faulted, etc. The actual bit mapping is determined by the Set-Up
parameters explained in the Set-Up Parameter section. The Digital Outputs
are updated every 20 milliseconds.
