Function
Output when the feedback value falls below
the lower limit of PID control.
Output when the feedback value rises above
the upper limit of PID control
Output when forward rotation is performed in
PID control.
Used when the bypass-inverter switchover
function is used.
Output at the time of a fan alarm.
Output when the heatsink temperature
reaches about 85% of the heatsink overheat
protection operation temperature.
Output when the inverter is running and start
command is on.
Output when the power failure-time
deceleration function is executed.
(retained until release)
Output during PID control.
Output when the absolute value of deviation
exceeds the limit value.
Output during retry processing.
Output when the PID output interruption
function is executed.
Used when using advanced PID control
(pump function).
Output in pulses every time the accumulated
output power of the inverter reaches the
Pr.799 setting.
Output during power failure or under voltage
of AC power.
Output when any of the control circuit
capacitor, main circuit capacitor and inrush
current limit circuit or the cooling fan
approaches the end of its service life.
Output when a fault occurs due to the
internal circuit failure of inverter wiring
mistake.
