12.10.4 PID Sleep
PID sleep function
• In the case of using this function, set 01 (output
low) or 02 (SLEP terminal) to PID sleep condition
selection [AH-85].
• You can change the start/cancel time and level of
the sleep operation depending on the usage.
Parameter
Input terminal function
• You can choose cancellation of the PID sleep
status from 01 (deviation amount), 02 (feedback
low), and 03 (WAKE terminal) of the PID wake
condition selection [AH-93].
• In the case of canceling the PID sleep status by
deviation, cancellation will only be activated when
deviation increases in a direction of lower output,
even if PID1 deviation [AH-02] was set to 01 and
PID deviation ± was switched.
Item Parameter Data Description
PID sleep condition selection [AH-85]
00 Disable
01 Starts sleep operation when output is low
02
Starts operation at the rising edge of
the [
SLEP] terminal
PID sleep start level [AH-86] 0.00~590.00(Hz)
Is a level of making a judgment of sleep
operation for the output speed when
[AH-85] = 01.
PID sleep operation time [AH-87] 0.00~100.00(s)
Is stand-by time before shifting to sleep
operation.
Boost selection prior to PID
sleep
[AH-88]
00 Disable
01 Boosts target value before sleep operation.
Boost time prior to PID sleep [AH-89] 0.00~100.00(s) Is actuation time prior to PID sleep.
Boost amount prior to PID
sleep
[AH-90] 0.00~100.00(%)
Sets a boost amount to be added to target
value before sleep.
Minimum operation time prior
to PID sleep
[AH-91] 0.00~100.00(s)
Does not start sleep operation until [AH-91]
has elapsed from start.
PID sleep status minimum
retaining
time
[AH-92] 0.00~100.00(s)
Retains the sleep status until [AH-92] has
elapsed, once the sleep operation started.
PID wake condition selection [AH-93]
01
Cancels the sleep operation when a
deviation amount increases in a
deceleration direction.
02
Cancels the sleep operation when
feedback value decreases.
03
Cancels the operation at the rising
edge of the [
WAKE] terminal
PID wake start level [AH-94] 0.00~100.00(%)
Cancels the operation when feedback
value goes below the set value when
[AH-93] is 02.
PID wake operation time [AH-95] 0.00~100.00(s)
Is stand-by time for operation cancellation
when [AH-93] is 02.
PID wake start deviation
amount
[AH-96] 0.00~100.00(%)
Cancels the operation when a deviation
between target value and feedback value
increases when [AH-93] is 01.
Item Terminal
name
Data Description
PID sleep start terminal [SLEP] 057
Starts the sleep function with the terminal
when
[AH-85] = 02.
PID sleep cancel terminal [WAKE] 058
Cancels the sleep function with the terminal
when [AH-93] = 03.
