Alarms
16
The configuration bits act as a mask to block or pass through the alarm condition
to the active condition. An active alarm will be indicated on the LCD HIM and
will cause the drive alarm status bit to go high ("1") in the Drive Status word (Bit
6, parameter 209). This bit can then be linked to a digital output for external
annunciation. As default, all configuration bits are high ("1"). Note that setting a
configuration bit to "0" to "mask" an alarm does not affect the status bit in the
Drive Alarm parameter, only its ability to annunciate the condition.
Application
A process is being controlled by a PowerFlex drive. The speed reference to the
drive is a 4-20 mA analog signal from a sensor wired to Analog Input 1.
The input is configured for mA by setting the corresponding bit in [Anlg In
Config] to "1"
320 [Anlg In Config]
Selects the mode for the analog inputs.

Analog In Config
The input is scaled for 4-20 mA by setting [Analog In 1 Lo] to "4" mA and
[Analog In 1 Hi] to "20" mA.
The signal is designated as the active speed reference by setting [Speed Ref A Sel]
to its factory default value of "1"
090 [Speed Ref A Sel]
Selects the source of the speed reference to the drive
unless [Speed Ref B Sel] or [Preset Speed 1-7] is
selected.
