SLEEP SELECTION
-11…11 - 0
Defines the control for the PID sleep function.
0 = NOT SEL – Disables the PID sleep control function.
1 = DI1 – Defines digital input 1 as the control for the PID sleep function.
• Activating the digital input activates the sleep function.
• De-activating the digital input restores PID control.
2…5 = DI2…DI5 – Defines digital input DI2…DI5 as the control for the PID sleep
function.
• See DI1 above.
9…11 = SUPRV1 UNDER…SUPRV3 UNDER – The function is activated when
parameter 3201 SUPERV 1 PARAM stays over the high limit defined by parameter
3203 SUPERV 1 LIM HI.
The internal sleep criteria set by parameters 4023 PID SLEEP LEVEL and 4025
WAKE-UP DEV are not effective. The sleep start and stop delay parameters 4024
PID SLEEP DELAY and 4026 WAKE-UP DELAY are effective.
7 = INTERNAL – Defines the output rpm/frequency, process reference, and process
actual value as the control for the PID sleep function. Refer to parameters 4025
WAKE-UP DEV and 4023 PID SLEEP LEVEL.
-1 = DI1(INV) – Defines an inverted digital input DI1 as the control for the PID sleep
function.
• De-activating the digital input activates the sleep function.
• Activating the digital input restores PID control.
-2…-5 = DI2(INV)…DI5(INV) – Defines an inverted digital input DI2…DI5 as the control
for the PID sleep function.
• See DI1(INV) above.
-9…-11 = SUPRV1 UNDER…SUPRV3 UNDER – The function is activated when
parameter 3201 SUPERV 1 PARAM stays below the low limit defined by
parameter 3202 SUPERV 1 LIM LO.
The internal sleep criteria set by parameters 4023 PID SLEEP LEVEL and 4025
WAKE-UP DEV are not effective. The sleep start and stop delay parameters 4024
PID SLEEP DELAY and 4026 WAKE-UP DELAY are effective.
