P1030 – Main PID Feedback Alarm Conf.
Adjustable 0 = Disable
Range: 1 = Enable Alarm
2 = Enable Fault
Properties: cfg

via HMI:
Description:
This parameter defines how the low level and high level alarm conditions will be handled for the process variable
of the main PID controller.
P1030
It that defines the alarms for low level and high level of the process variable of the main PID controller will be
0
disabled.
It defines that the alarms for low level and high level of the process variable of the main PID controller will be enabled
1 and just the message of the respective alarm will be generated, while the main PID controller remains active and
controlling the motor driven by the CFW501 frequency inverter.
It defines that the alarms for low level and high level of the process variable of the main PID controller will be enabled
2 and a fault will be generated on the CFW501 frequency inverter. The message of the respective alarm will be
generated during the deceleration of the motor and the respective fault after the shutdown of the motor.

Description:
This parameter defines the value below which the process variable of the main PID controller will be considered
low level according to its engineering unit.
NOTE!
This parameter will be viewed according to the selection of the parameters for the engineering unit
1 (P0510 and P0511).
