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.

B5-11 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.
