Actual signals and parameters 245
4028 PID OUT MIN Defines the minimum value of PID output. -100.0%
-1000.0…
1000.0%
Value in percent 1 = 0.1%
4029 PID OUT MAX Defines the maximum value of PID output. 100.0%
-1000.0…
1000.0%
Value in percent 1 = 0.1%
4030 SLEEP BOOST
TIME
Defines the boost time for the sleep boost step. See
parameter 4031 SLEEP BOOST STEP.
0.0 s
0.0…3600.0 s Sleep boost time 1 = 0.1 s
4031 SLEEP BOOST
STEP
When the drive is entering sleep mode, the reference (PID
setpoint) is increased by this percentage for the time
defined by parameter 4030 SLEEP BOOST TIME.
0.0%
0.0…100.0% Sleep boost step 1 = 0.1%
4032 PID REF ACC
TIME
Defines the time for the reference (PID setpoint) increase
from 0 to 100%.
Note: Parameters 4032…4036 are active even if the
process PID set 2 (group 41 PROCESS PID SET 2) is used.
0.0 s
0.0…1800.0 s Acceleration time 1 = 0.1 s
4033 PID REF DEC
TIME
Defines the time for the reference (PID setpoint) decrease
from 100 to 0%
0.0 s
0.0…1800.0 s Deceleration time 1 = 0.1 s
4034 PID REF
FREEZE
Freezes the input (reference, PID setpoint) of the process
PID controller. This feature is useful when the reference is
based on a process actual value connected to an analog
input, and the sensor must be serviced without stopping the
process.
The input of the PID controller is frozen as long as the
selected digital input is ON for parameter values DI1…DI5
or OFF for parameter values DI1(INV)…DI5(INV).
See also parameter 4035.
NOT SEL
NOT SEL Not selected 0
DI1 Reference is frozen on the rising edge of digital input DI1. 1
DI2 See selection DI1.2
DI3 See selection DI1.3
DI4 See selection DI1.4
DI5 See selection DI1.5
DI1(INV) Reference is frozen on the falling edge of digital input DI1. -1
DI2(INV) See selection DI1(INV).-2
DI3(INV) See selection DI1(INV).-3
