8.0 System Status Monitoring
The inverter operates with varying levels of supply voltage and current. A variable output
frequency of voltage and current is generated to drive the motor load. These input and output
levels of operating voltage and current are continually monitored by the inverter. It also monitors
for over temperature, input and output terminal settings, and condition of the microprocessor
with associated memory elements. These operating settings and variables have a certain value
or "status" associated with them and are used for inverter operation. They can also be monitored
by the operator to show the setup and conditions existing at any time. Three types of status
monitoring are used and explained below.
8.1 Normal Status Monitoring
Normal status monitoring occurs during normal operation. The ST-CC terminal must be
closed to run. The following table shows applicable keys, display, and status conditions
for normal status monitoring. The display values are for factory settings where no trips
or errors occurred. The display will change only if a new value is programmed into the
associated group adjustment range or if trips or errors have occurred. Scrolling occurs
by repeatedly pressing the READ/WRITE key after output frequency is displayed. Trips
or errors that have occurred (up to a total of three), will be displayed in order immediately
after the keypad software version display.
