If the monitors seem more natural in terms of percentage, set b5-20= 1. If the monitors are easier to work with when
displaying the equivalent synchronous RPM, set b5-20= [the number of motor poles].
If another engineered unit, such a fpm or cfm, is desired, set b5-20= xxxxx where
Digits 1 through 4 set the desired number to be displayed at 100% speed.
Digit 5 determines the number of decimal places
For example:
If b5-20= 10425 then at 100% output the digital operator would display 42.5 for monitor U1-38 or U1-24.
b5-21 Sleep Source
Setting
0 SFS Input (Output of PI block)
1 PI Setpoint (factory default)
2 Snooze
Parameter b5-21 selects the sleep function characteristic action:
When b5-21= "0: SFS Input" the sleep function start level (b5-15) is compared to the Drive's output (Speed Command after PI
block). This is the setting that should be used for open loop or closed loop control.
It is also possible to have the sleep function start level (b5-15) compared to the Drive input or setpoint. For this special
application set b5-21= "1: PI Setpoint".
When b5-21= "2: Snooze" a variation of the sleep function called "Snooze" is enabled, see parameter b5-22 to b5-27.
IMPORTANT
b5-22 PI Snooze Level
Setting Range: 0 to 100%
Factory Default: 0%
b5-23 PI Snooze Delay Time
Setting Range: 0 to 3600 Seconds
Factory Default: 0 Seconds

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