Setting Up Parameters

Analog Inputs View

The FM-3 module is able to use the analog input circuitry located on the drive. The analog input accepts a +10 to –10 Volt signal. The analog input can be setup on the Analog view, which is located underneath the I/O Setup group in the PowerTools Pro hierarchy.

Figure 52: Analog Inputs View

The drive has a 14-bit analog to digital converter (A/D) which is used to transform the analog voltage to a usable parameter in the FM-3 module. The analog input is scanned every 100 microseconds.

User Units

This parameter allows the user to enter a 12 character string to be used as units for the analog input parameter.

Decimal

This parameter defines how many digits (up to six) are used after the decimal place for the user unit scaled analog input parameter. This defines the maximum resolution of the analog input parameter.
