Start-Up
4023 PID SLEEP LEVEL
Sets the motor speed / frequency that enables the PID sleep
function – a motor speed / frequency below this level, for at least
the time period 4024
PID SLEEP DELAY enables the PID sleep
function (stopping the drive).
• Requires 4022 = 7
INTERNAL.
• See figure: A = PID output level; B = PID process feedback.
4024 PID SLEEP DELAY
Sets the time delay for the PID sleep function – a motor speed /
frequency below 4023
PID SLEEP LEVEL for at least this time period
enables the PID sleep function (stopping the drive).
See 4023 PID SLEEP LEVEL above.
4025 WAKE-UP DEV
Defines the wake-up deviation – a deviation from the setpoint
greater than this value, for at least the time period 4026
WAKE-UP
DELAY, re-starts the PID controller.
• Parameters 4006 and 4007 define the units and scale.
• Parameter 4005 = 0,
Wake-up level = Setpoint - Wake-up deviation.
• Parameter 4005 = 1,
Wake-up level = Setpoint + Wake-up deviation.
• Wake-up level can be above or below setpoint.
See figures:
• C = Wake-up level when parameter 4005 = 1
• D = Wake-up level when parameter 4005 = 0
• E = Feedback is above wake-up level and lasts longer than 4026
WAKE-UP DELAY – PID function wakes up.
• F = Feedback is below wake-up level and lasts longer than 4026
WAKE-UP DELAY – PID function wakes up.
4026 WAKE-UP DELAY
Defines the wake-up delay – a deviation from the setpoint greater
than 4025
WAKE-UP DEV, for at least this time period, re-starts the
PID controller.
4027 PID 1 PARAM SET
Process PID (PID1) has two separate sets of parameters, PID set 1 and PID set 2.
• PID set 1 uses parameters 4001…4026.
• PID set 2 uses parameters 4101…4126.
PID 1 PARAM SET defines which set is selected.
0 =
SET 1 – PID Set 1 (parameters 4001…4026) is active.
1 =
DI1 – Defines digital input DI1 as the control for PID Set selection.
• Activating the digital input selects PID Set 2.
• De-activating the digital input selects PID Set 1.
2…6 =
DI2…DI6 – Defines digital input DI2…DI6 as the control for PID Set selection.
•See
DI1 above.
7 =
SET 2 – PID Set 2 (parameters 4101…4126) is active.
-1 =
DI1(INV) – Defines an inverted digital input DI1 as the control for PID Set selection.
• Activating the digital input selects PID Set 1.
• De-activating the digital input selects PID Set 2.
-2…-6 =
DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the control for PID Set selection.
•See
DI1(INV) above.
