Fig. 9.2.4.2b PID Sleep Function Graph
When the PID output falls below the Sleep Start Level P2-01 for a time exceeding the Sleep Start Delay P2-02
setting, the sleep function will be activated.
The PID Sleep function can also be activated using a digital input. When the corresponding digital input
Sn-25 –28 = 33 is ON for a time exceeding Sleep Start Delay P2-02 setting, the sleep function will be activated.
If the sleep start level P2-01 is less than the minimum output frequency set by Cn-07, and none of the multi-
Functional input terminals Sn-25-28 are set to =33 (PID Sleep), the sleep function will be disabled.
A
"DI PID Sleep Setting Error"
will occur if any of Sn-25-28 is set to =33 (PID Sleep) and:
1.The PID function is disabled, Sn-64 = 0 or,
2.The PID sleep function is disabled, P1-04 = 0.
The PID Wakeup Direction P1-05 is used to set the condition for PID Wakeup Check.
0: PID Wakeup while the PID feedback rises above the wakeup level.
1: PID Wakeup while the PID feedback falls below the wakeup level.
While the PID sleep function is valid, the PID wakeup direction also affects the PID function.
Sleep Wakeup Level P2-03 and Sleep Wakeup Delay P2-04, are used for PID Wakeup Check. When the inverter
is in the PID sleep mode, and the PID feedback falls below or rises above (direction set by P1-05 PID Wakeup
Direction) the sleep wakeup level P2-03 for a time exceeding the programmed wakeup delay time P2-04, the
inverter will exit the sleep mode and resume run.
If PID sleep is enabled and the inverter is in PID sleep mode, the During PID Sleep Monitor Un-35 will be 1.
If any of Multi-Function Output Functions Sn-30 -32 is set as "During PID Sleep", the corresponding output will be
ON.
If the inverter is in PID sleep mode, the accumulated integration error of the PID function will be cleared.
External PID
The following parameters pertain to the external PID function input and output terminals.
P1-06
External PID function (Cannot be changed during operation)
P1-06=0: External PID function disabled
1: External PID Enabled. Terminal AO1 is the output signal of the external PID function.
2: External PID Enabled. Terminal AO2 is the output signal of the external PID function.
P1-07
External PID source
P1-07=0: Set point parameter
1: Terminal VIN
2: Terminal AIN
3: Terminal AUX
4: Set point RS485 serial communication
