• Graphs
The LV-DS can display real-time performance information for:
• current
• motor temperature
• motor kW
• motor kVA
• motor power factor
The newest information is displayed at the right hand edge of the screen. Older data is not stored.
To access the graphs or to change which graph is shown, press the GRAPHS button.
The graph can also be paused, to allow past performance to be analysed. To pause the graph, press and hold
the GRAPHS button for more than 0.5 seconds. To unpause the graph, press the GRAPHS button again.
NOTE
The LV-DS will not collect data while the graph is paused. When graphing resumes, a small gap
will be shown between the old data and the new data.
7.4. Start, Stop and Reset Commands
The soft starter can be controlled in three ways:
• using the buttons on the keypad
• via remote inputs
• via a serial communication link
The LOCAL/REMOTE button controls whether the LV-DS will respond to local control (via the keypad) or
remote control (via the remote inputs). The LV-DS can also be set to allow local control only or remote control
only, using parameter 6A Local/Remote. The Local LED on the keypad is on when the soft starter is in local
control mode and off when the soft starter is in remote control mode.
