b5-15 Sleep Function Start Level
b5-16 Sleep Delay Time
b5-21 Sleep Input Source
The Sleep Function prevents the Drive from running when the PI loop output or the speed command is so low that no usable
work is being done and equipment damage may result, the Sleep Function. If the Drive’s output drops below the level set by PI
Sleep Function Start Level (b5-15) and remains there at least as long as the delay time determined by the PI Sleep Delay Time
(b5-16), then the Drive’s internal run command drops out and the Drive output ceases. Though the Drive’s output has ceased,
all other Drive functions continue. Once the Drive’s output returns to a level above the PI Sleep Function Start Level (b5-15)
and remains above that level for at least the PI Sleep Delay Time (b5-16), the internal run command returns and the Drive out-
put begins again.

The sleep function can be used even if the PI function is disabled (b5-01=0).
