the typical operating point of the
system.
Click in the VLP Minimum
field and, using the Rotary
Encoder, slowly decrease the
VLP Minimum value while observing the LED display.
If either of the conditions listed below should occur while decreasing the VLP
Minimum value, increase the VLP Minimum number until the condition is no longer
true to set the VLP Minimum:
• The motor stalls,
• The output frequency is greater than the setting of
F505 , or
• The output frequency no longer changes with continued VLP number changes.
The VLP Minimum setting (
