P1034 – Time for High Level Alarm of the Process Variable of the Main PID Controller
Adjustable
Range:
0.00 to 650.00 s
Factory
Setting:
5.00 s
Properties:
Access groups
via HMI:
HVAC
Description:
This parameter defines the time with the high level condition of the process variable of the main PID controller,
so that the alarm message “A0762: High level alarm of the process variable of the main PID controller“ will be
generated. With P1030 programmed for 2, the fault “F0763: High level fault of the process variable of the main
controller” will be generated after the motor driven by the CFW501 frequency inverter is decelerated and is no
longer spinning.
NOTE!
The value set to 0.00s s disables the alarm detection.
18.6.1 Sleep Mode
This parameter group allows the user to configure the sleep mode operation for Main PID controller.
Sleep Mode
is a state of the controlled system where the control request is null or almost null, and may at this
moment, stop the motor driven by CFW501 frequency inverter; that prevents the motor from continuing to run at a
low speed which helps little or does not help at all the controlled system. However, the process variable continues
to be monitored so that, when necessary (reaching a level below a required setpoint), the controlled system can
start the motor again (wakeup mode).
NOTE!
The sleep mode works only if Main PID controller is enabled and in automatic mode.
P1036 – Main PID Controller Sleep Mode Speed
Adjustable
Range:
0 to 18000
Factory
Setting:
350
Properties:
Access groups
via HMI:
HVAC
Description:
This parameter defines the motor speed below which will be considered that the speed control is low, thus
activating the sleep mode.
NOTE!
This parameter can be displayed in Hz or rpm as selection in the indirect engineering unit 4 parameters
(P0516 and P0517):
Set P0516 in 13 (Hz) and P0517 in 1 (wxy.z) for displaying in Hz.
Set P0516 in 3 (rpm) and P0517 in 0 (wxyz) for displaying in rpm.
NOTE!
Value set to 0 disables the sleep mode.
