0 : Reverse Disabled
Negative PID output will be limited to 0 and stop the drive.
1 : Reverse Enabled
The drive will run reversely if PID output is negative.
■ PID Feedback Low /High Detection
This detects whether the sensor or the sensor wiring is broken. Always use this function during
PID control so as to avoid machinery accelerating to the maximum frequency cause by PID
feedback low / high.
· PID Feedback Low
This will be detected when the value is lower than the set level for longer than the set time.
· PID Feedback High
This will be detected when the value is higher than the set level for longer than the set time.
The PID Feedback Low Detection operation is illustrated below. Same way applies to PID
Feedback High Detection.
