This parameter sets the gain of the PID output. The PID output can be monitored by parameter U1-37
PID Output Monitor. Refer to PID Block Diagram Figure 9.
This parameter is used when the motor is required to change direction during PID operation in
response to a negative PID output signal. The PID output can be monitored using parameter U1-37
PID Output Monitor.
Note: When Reverse Prohibit B1-04 is selected, reverse will not operate.
This parameter is used to select what action the inverter will take on a loss of PID feedback. A loss of
PID feedback occurs when the feedback signal falls below the B5-13 Feedback Loss Detection Level
for the time set by B5-14 Feedback Loss Detection Time.
B5-10 PID Output Gain
<1110>
Output Gain A A A A
B5-11 PID Output Reverse <1110> Output Rev Sel A A A A
Setting Description
0 Zero limit (factory default)
When PID output is negative, motor direction is not changed. The PID output
is limited to 0.
1 Reverse
When PID output is negative the motor will reverse direction.
B5-12 Loss of Feedback Action <1110> Fb Los Det Sel A A A A
Setting Description
0 Disabled (factory default)
PID feedback missing detection is disabled.
1 Alarm
PID feedback missing detection is enabled. Operation continues after loss of
feedback. The text “Fbl” will be displayed on the digital operator.
2 Fault
PID feedback missing detection is enabled. The inverter output to the motor
is shut off (the motor is stopped) and “Fbl” is displayed on the digital operator.
