B5-10 PID Output Gain
Setting Range:
Factory Default:
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.
B5-11 PID Output Reverse
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.
Setting
0
1
Note: When Reverse Prohibit B1-04 is selected, reverse will not operate.
B5-12 Loss of Feedback Action
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.

0.0 to 25.0
1.0

Zero limit (factory default)
When PID output is negative, motor direction is not changed. The PID output
is limited to 0.
Reverse
When PID output is negative the motor will reverse direction.
<1110>
Disabled (factory default)
PID feedback missing detection is disabled.
Alarm
PID feedback missing detection is enabled. Operation continues after loss of
feedback. The text "Fbl" will be displayed on the digital operator.
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.
