PI Sleep Input Source
Selects the Sleep Function characteristic action. When b5-21 is set to 1, the Sleep Function Start Level (b5-15) is compared
to the output of the drive (Speed Command after PI Block). Use this setting for open loop control.
The Sleep Function Start Level (b5-15) can be compared to the drive input or setpoint by setting b5-21 to 0.
When b5-21 is set to 2, a variation of the Sleep Function called “Snooze” is enabled. See parameters b5-22 to b5-27 for details.
