Parameters
4018 ACT1 MINIMUM -1000…1000% 1% 0%
Sets the minimum value for
ACT1.
• Scales the source signal used as the actual value
ACT1 (defined by
parameter 4016
ACT1 INPUT). For parameter 4016 values 6 (COMM
ACT 1) and 7 (COMM ACT 2) scaling is not done.
• See the figure: A= Normal; B = Inversion (
ACT1 MINIMUM > ACT1
MAXIMUM)
4019 ACT1 MAXIMUM -1000…1000% 1% 100%
Sets the maximum value for ACT1.
• See 4018
ACT1 MINIMUM.
4020 ACT2 MINIMUM -1000…1000% 1% 0%
Sets the minimum value for
ACT2.
• See 4018
ACT1 MINIMUM.
4021 ACT2 MAXIMUM -1000…1000% 1% 100%
Sets the maximum value for ACT2.
• See 4018
ACT1 MINIMUM.
4022 SLEEP SELECTION -6…7 1 0 (
NOT SEL)
Defines the control for the PID sleep function.
0 =
NOT SEL– Disables the PID sleep control function.
1 =
DI1 – Defines digital input DI1 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…6 =
DI2…DI6 – Defines digital input DI2…DI6 as the control for the PID sleep function.
•See
DI1 above.
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…-6 =
DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the control for the PID sleep function.
•See
DI1(INV) above.
