Chapter 4: AC Drive Parameters
4–38
Desired Frequency
Default Setting: 0.0
Range: 0.0 to 400.0 Hz
•If a Multi-function output terminal is set to function as Desired Frequency Attained
(P3.11 or P3.12 = 04 or 05), then the output will be activated when the
programmed frequency is attained.
Desired Current
Default Setting: 0.0
Range: 0.0 to <Drive Rated Amps>
PID Deviation Level
Default Setting: 10.0
Range: 1.0 to 50.0%
If a Multi-function Output terminal is set to PID Deviation Alarm (RO, DO1-DO3
setting = 10), then the output will be activated when the amount of deviation
between the SP (set point) and PV (process variable) in the PID loop constantly
exceeds the threshold set by this parameter for the period of time set by P3.19.
This is defined in percentage of PV Value (see P7.01).
• This parameter is used in conjunction with P3.19, PID Deviation Time.
PID Deviation Time
Default Setting: 5.0
Range: 0.1 to 300.0 sec
If a Multi-function Output terminal is set to PID Deviation Alarm (RO, DO1-DO3
setting = 10), then the output will be activated when the amount of deviation
between the SP (set point) and PV (process variable) in the PID loop constantly
exceeds the threshold set by P3.18 for the period of time set by this parameter.
• This parameter is used in conjunction with P3.18, PID Deviation Level.
Desired Frequency 2
Default Setting: 0.0
Range: 0.0 to 400.0 Hz
P3.20
P3.19
P3.18
P3.17
