 External PID control 1 to 3 (Feedback error lower-limit) (J529, J629, J679)
J529/J629/J679 specifies the upper limit for feedback errors in a physical quantity.
- Data setting range: -999.00 to 0.00 to 999.00, Auto = 105%
The physical quantity is dependent on the display unit and maximum/minimum scale
specified by the following function codes.
External PID control 1
External PID control 2
External PID control 3
 External PID control 1 to 3 (Feedback error lower-limit) (J530, J630, J680)
J530/J630/J680 specifies the lower limit for feedback errors in a physical quantity. The
physical quantity is dependent on the display unit and maximum/minimum scale specified by
the function codes listed above.
- Data setting range: -999.00 to 0.00 to 999.00, Auto = -5%
 External PID control 1 to 3 (Feedback error detection time) (J531, J631, J681)
J531/J631/J681 specifies the feedback error detection time for the upper-limit
(J529/J629/J679) and lower-limit (J530/J630/J680). If the detection time has elapsed after a
feedback error occurred, the inverter regards it as an error.
- Data setting range: 0 to 300.0 (s)
