Function
Output when the output power is lower than
Zero current
the Pr. 152 setting for longer than the time
detection
set in Pr. 153.
Output when the feedback value falls below
PID lower limit
the lower limit of PID control.
Output when the feedback value rises above
PID upper limit
the upper limit of PID control
PID forward/reverse Output when forward rotation is performed in
rotation output PID control.
Electric bypass MC1
Used when the bypass-inverter switchover
Electric bypass MC2
function is used.
Electric bypass MC3
Fan fault output Output at the time of a fan alarm.
Output when the heatsink temperature
Heatsink overheat
reaches about 85% of the heatsink overheat
pre-alarm
protection operation temperature.
During inverter
Output when the inverter is running and start
running and start
command is on.
command is on
During deceleration at Output when the power failure-time
occurrence of power deceleration function is executed.
failure (retained until release)
During PID control
Output during PID control.
activated
Output when the absolute value of deviation
PID deviation limit
exceeds the limit value.
During retry Output during retry processing.
PID output Output when the PID output interruption
interruption function is executed.
Output in pulses every time the accumulated
Pulse train output of
output power of the inverter reaches the
output power
Pr.799 setting.
Output during power failure or under voltage
DC feeding
of AC power.
Output when any of the control circuit
capacitor, main circuit capacitor and inrush
Life alarm
current limit circuit or the cooling fan
approaches the end of its service life.
Output when a fault occurs due to the
Fault output 3
internal circuit failure of inverter wiring
(power-off signal)
mistake.
Turned on and off alternately every time the
Power saving power saving average value is updated
average value when the power saving monitor is used.
updated timing Cannot be set to Pr. 195 and Pr. 196 (relay
output terminal).
Average current value and maintenance
Current average timer value are output as pulses.
value monitor signal Cannot be set to Pr. 195 and Pr. 196 (relay
output terminal).
Output when the fault occurs. Continues
outputting the signal during inverter reset
Fault output 2
and stops outputting after reset is cancelled.
*2
Maintenance timer Output when Pr. 503 rises to or above the Pr.
signal 504 setting.
Output to the terminal when a value is set to
Remote output
the parameter.
Output when an alarm (fan failure or
Alarm output
communication error warning) occurs.
